My Long List of Amplifiers and My Personal Review of Each!


So I have been in a long journey looking to find the best amplifiers for my martin logan montis. As you know, the match between an amplifier and speakers has to be a good "marriage" and needs to be blend exquisitely. Right now, I think I might have found the best sounding amplifier for martin logan. I have gone through approximately 34-36 amplifiers in the past 12 months. Some of these are:

Bryston ST, SST, SST2 series
NAD M25
PARASOUND HALO
PARASOUND CLASSIC
KRELL TAS
KRELL KAV 500
KRELL CHORUS
ROTEL RMB 1095
CLASSE CT 5300
CLASSE CA 2200
CLASSE CA 5200
MCINTOSH MC 205
CARY AUDIO CINEMA 7
OUTLAW AUDIO 755
LEXICON RX7
PASS LABS XA 30.8
BUTLER AUDIO 5150
ATI SIGNATURE SERIES 6005

With all that said, the amplifiers I mentioned above are the ones that in my opinion are worth mentioning. To make a long story short, there is NO 5 CHANNEL POWER AMP that sounds as good as a 3ch and 2ch amplifier combination. i have done both experiments and the truth is that YOU DO lose details and more channel separation,etc when you select a 5 channel power amplifier of any manufacturer.
My recollection of what each amp sounded like is as follows:

ATI SIGNATURE SERIES 6005 (great power and amazing soundstage. Very low noise floor, BUT this amplifiers NEEDS TO BE cranked up in order to fully enjoy it. If you like listening at low volume levels or somewhat moderate, you are wasting your time here. This amp won’t sound any different than many other brands out there at this volume. The bass is great, good highs although they are a bit bright for my taste)

NAD M25 (very smooth, powerful, but somewhat thin sounding as far as bass goes)
Bryston sst2(detailed, good soundstage, good power, but can be a little forward with certain speakers which could make them ear fatiguing at loud volumes)

Krell (fast sounding, nice bass attack, nice highs, but some detail does get lost with certain speakers)

rotel (good amp for the money, but too bright in my opinion)

cary audio (good sound overall, very musical, but it didn’t have enough oomph)

parasound halo (good detail, great bass, but it still holds back some background detail that i can hear in others)

lexicon (very laid back and smooth. huge power, but if you like more detail or crisper highs, this amp will disappoint you)

McIntosh mc205 (probably the worst multichannel amp given its price point. it was too thin sounding, had detail but lacked bass.

butler audio (good amplifier. very warm and smooth sweet sounding. i think for the money, this is a better amp than the parasound a51)

pass labs (very VERY musical with excellent bass control. You can listen to this for hours and hours without getting ear fatigue. however, it DOES NOT do well in home theater applications if all you have is a 2 channel set up for movies. The midrange gets somewhat "muddy" or very weak sounding that you find yourself trying to turn it up.

classe audio (best amplifier for multi channel applications. i simply COULDNT FIND a better multi channel amplifier PERIOD. IT has amazing smoothness, amazing power and good bass control although i would say krell has much better bass control)

Update: The reviews above were done in January 2015. Below is my newest update as of October 2016:



PS AUDIO BHK 300 MONOBLOCKS: Amazing amps. Tons of detail and really amazing midrange. the bass is amazing too, but the one thing i will say is that those of you with speakers efficiency of 87db and below you will not have all the "loudness" that you may want from time to time. These amps go into protection mode when using a speaker such as the Salon, but only at very loud levels. Maybe 97db and above. If you don’t listen to extreme crazy levels, these amps will please you in every way.

Plinius Odeon 7 channel amp: This is THE BEST multichannel amp i have ever owned. Far , but FAR SUPERIOR to any other multichannel amp i have owned. In my opinion it destroyed all of the multichannel amps i mentioned above and below. The Odeon is an amp that is in a different tier group and it is in a league of its own. Amazing bass, treble and it made my center channel sound more articulate than ever before. The voices where never scrambled with the action scenes. It just separated everything very nicely.

Theta Dreadnaught D: Good detailed amp. Looks very elegant, has a pleasant sound, but i found it a tad too bright for my taste. I thought it was also somewhat "thin" sounding lacking body to the music. could be that it is because it is class d?

Krell Duo 300: Good amp. Nice and detailed with enough power to handle most speakers out there. I found that it does have a very nice "3d" sound through my electrostatics. Nothing to fault here on this amp.
Mark Levinson 532H: Great 2 channel amp. Lots of detail, amazing midrange which is what Mark Levinson is known for. It sounds very holographic and will please those of you looking for more detail and a better midrange. As far as bass, it is there, but it is not going to give you the slam of a pass labs 350.5 or JC1s for example. It is great for those that appreciate classical music, instrumental, etc, but not those of you who love tons of deep bass.

 It is articulate sounding too
Krell 7200: Plenty of detail and enough power for most people. i found that my rear speakers contained more information after installed this amp. One thing that i hated is that you must use xlr cables with this amp or else you lose most of its sound performance when using RCA’s.

Krell 402e: Great amp. Very powerful and will handle any speaker you wish. Power is incredible and with great detail. That said, i didn’t get all the bass that most reviewers mentioned. I thought it was "ok" in regards to bass. It was there, but it didn’t slam me to my listening chair.

Bryston 4B3: Good amp with a complete sound. I think this amp is more laid back than the SST2 version. I think those of you who found the SST2 version of this amp a little too forward with your speakers will definitely benefit from this amp’s warmth. Bryston has gone towards the "warm" side in my opinion with their new SST3 series. As always, they are built like tanks. I wouldn’t call this amp tube-like, but rather closer to what the classe audio delta 2 series sound like which is on the warm side of things.

Parasound JC1s: Good powerful amps. Amazing low end punch (far superior bass than the 402e). This amp is the amp that i consider complete from top to bottom in regards to sound. Nothing is lacking other than perhaps a nicer chassis. Parasound needs to rework their external appearance when they introduce new amps. This amp would sell much more if it had a revised external appearance because the sound is a great bang for the money. It made my 800 Nautilus scream and slam. Again, amazing low end punch.

Simaudio W7: Good detailed amp. This amp reminds me a lot of the Mark Levinson 532h. Great detail and very articulate. I think this amp will go well with bookshelves that are ported in order to compensate for what it lacks when it comes to the bass. That doesn’t mean it has no bass, but when it is no Parasound JC1 either.
Pass labs 350.5: Wow, where do i begin? maybe my first time around with the xa30.8 wasn’t as special as it was with this monster 350.5. It is just SPECTACULAR sounding with my electrostatics. The bass was THE BEST BASS i have ever heard from ANY amp period. The only amp that comes close would be the jC1s. It made me check my settings to make sure the bass was not boosted and kept making my jaw drop each time i heard it. It totally destroyed the krell 402e in every regard. The krell sounded too "flat" when compared to this amp. This amp had amazing mirange with great detail up top. In my opinion, this amp is the best bang for the money. i loved this amp so much that i ended up buying the amp that follows below.

Pass labs 250.8: What can i say here. This is THE BEST STEREO AMP i have ever heard. This amp destroys all the amps i have listed above today to include the pass labs 350.5. It is a refined 350.5 amp. It has more 3d sound which is something the 350.5 lacked. It has a level of detail that i really have never experienced before and the bass was amazing as well. I really thought it was the most complete power amplifier i have ever heard HANDS DOWN. To me, this is a benchmark of an amplifier. This is the amp that others should be judged by. NOTHING is lacking and right now it is the #1 amplifier that i have ever owned.

My current amps are Mcintosh MC601s: i decided to give these 601s a try and they don’t disappoint. They have great detail, HUGE soundstage, MASSIVE power and great midrange/highs. The bass is great, but it is no pass labs 250.8 or 350.5. As far as looks, these are the best looking amps i have ever owned. No contest there. i gotta be honest with you all, i never bought mcintosh monos before because i wasn’t really "wowed" by the mc452, but it could have been also because at that time i was using a processor as a preamp which i no longer do. Today, i own the Mcintosh C1100 2 chassis tube preamp which sounds unbelievable. All the amps i just described above have been amps that i auditioned with the C1100 as a preamp. The MC601s sound great without a doubt, but i will say that if you are looking for THE BEST sound for the money, these would not be it. However, Mcintosh remains UNMATCHED when it comes to looks and also resale value. Every other amp above depreciates much faster than Mcintosh.

That said, my future purchase (when i can find a steal of a deal) will be the Pass labs 350.8. I am tempted to make a preliminary statement which is that i feel this amp could be THE BEST stereo amp under 30k dollars. Again, i will be able to say more and confirm once i own it. I hope this update can help you all in your buying decisions!

As an FYI, I had no problem selling used Tekton speakers. Same for others trading up the Tekton line.  Great speakers for sure and becoming more and more popular. 
I have read this entire thread, but missed one thing.  In all these discussions of audio at the high end, no one ever speaks of vinyl and turntables as a source.

I was contemplating adding a turntable into my system to be able to enjoy some of my albums that have been in storage for 30 years.

I am not trying to create contoversy about costs and relative merits of tone arms, cartridges, etc.   Just curious about the lack of discussion regarding this source.
Greyhound,
i understand your point. That said, I don’t have any interest in tekton because once I’m tired of them, I’ll have to dump them with bulk trash in my neighborhood. I won’t be able to sell those things at all. Again, I don’t buy any brands that can be bought directly from the manufacturer. I don’t buy axiom, emotiva, svs, etc. Why ? Because I would be paying the same you, my dog, and everyone else pays for those things so once I’m done, No matter how good they are, they won’t be the last speaker i stay with. Sure, am I interested to hear them? Yes I am. Yes I know they do an in home trial but I’m not really the type to take advantage of that if I know all I want is to hear them with zero intentions of keeping them. 

@dguitarnut
You are the one who needs to reign in the Nonsense.
Tekton Lore is nowhere near the Double Impact, Encore,or Ulfberht .You need to open your mind . Have you heard the Double Impact , Encores ,or Ulfberhts ? Those are the Tekton speakers that could compete. Power cord cost doe not equal performance either. You guys kill me with the "This cost 4 times more so it is better " thinking.. TOTALLY WRONG
WC, you can’t say you know how they perform until you try them. You can think you do , but you would be wrong . !
Eric Alexander is laughing all the way to the BANK !!

Spinaker01,

Does the Roon do EQ in all freq? How do I find out about the Roon?

Viber6, yes the Roon parametric seems to accommodate any frequency I can throw at it. It is incredibly flexible and beneficial in my system. I only use a single band of EQ: 3db of cut centred at 600 Hz with a Q of 1.0. This is a pretty mild curve but makes a huge difference in my system/room configuration. For info on Roon, the Absolute sound has just published a fairly comprehensive article today on their website, check it out 
Viber6 open your mind that your $2000 Mytek with probably a $100 dollar power cord no way could hold its own against a D’agostino when just his power cords are as much as your entire setup? Really?
When other speaker designers look at that Tekton DI I bet they laugh their butts off......wow. You really need to reign in the nonsense 
Viber:
i can assure you there’s nothing slow about the 15 inch drivers in the Neolith. I have the best mid bass and low end oomph I’ve ever experienced from any of my former speakers. The Neolith has shown me how “not so good” the bass was from my previous speakers. 
I bet you if I brought back the magico s5 or Sasha 2s right now and played some
reggae, I’d be wondering if the woofers were stolen out of the cabinets. 

Let’s not forget, do you really think Martin Logan would use subpar/slow drivers that can not keep up with the panel in the their statement Neolith? I’m sure they thought about this in the 2 years that this speaker took to design.
brhatten,
You raise interesting points about bass from larger versus smaller drivers.  Of course, larger woofers are capable of more output and deeper response, but it is difficult to get speed and accuracy from large more massive woofers.  You might be in the sweet spot with fairly large 10" and 12" woofers, executed optimally.  Big enough to get decent output and extension, and still get good speed.  If you desire dynamics and accuracy of bass, there is nothing like a bass horn.
dguitarnut,
Please open your mind to the fact that more expensive often doesn’t buy better sound. Yes, more expensive buys better parts, etc. But if the designer doesn’t listen or has questionable musical background/experience, a more musically perceptive designer can come up with better results using cheaper parts than an inferior designer with expensive parts.. For dynamic speakers, I happen to like the concept of the Tekton DI speaker where lots of tweeters can cover the lower part of the midrange. Small tweeters have more accuracy than larger drivers. Of course, the output from a small tweeter is limited, so the design of the Tekton enables satisfactory dynamics with more accuracy than the conventional dynamic speaker design. Good thinking doesn’t cost more than bad thinking. I would challenge anybody to beat my $2000 Mytek Brooklyn amp in a blind A/B of their super duper expensive amp. I will win in most but not all cases. My Rane (new $600) without EQ engaged will beat most far more expensive line stages, as noted by me and mrdecibel. Open your mind. Then add the EQ, or even use a more rudimentary tone control as WC is doing with the Neo, and you have a situation where the Neo without EQ is vastly inferior to the Neo when used with the EQ. You could get the world’s best million buck amp and preamp without EQ, and the Neo still won’t sound as good as with my Rane and the Mytek amp for small change. LEARN.
Whitecamacross,

Youve stated a couple times that the bass of the Neoliths are (way) better than the Wilsons and the Magico. Don’t you think that’s a product of the specific models of each of these speakers that you’ve owned. I would think that the Neolith with a 15” and a 13” woofer has a better chance of beating out a Wilson with two 8” woofers such as the Sasha’s.

I currently own the Maxx 2’s, comprised of a 12” and 10” (which doesn’t even approach what you’ve got in the Neolith) and I feel like the bass is a very strong point on the speaker.

If you every have the opportunity to move up the Wilson line, perhaps the bass response would fall more in line with what your hearing now. Although, I’m not sure the Alexia will get you there (disclaimer: I have not heard the Alexia). After all, there’s no replacement for displacement.
@dguitarnut I coudnt have said it better myself.... been trying to say that you can’t expect for a Honda Civic to give you the same experience as a Bugatti veyron just because it can go 200 mph, it can go in reverse and make u turns. Just a totally different class and to your point, no speaker worth 10k can compete with speakers costing 4 times their price. Sure, it can show you how good it is given its price and also show you the law of diminishing returns in spades but nobody said that the extra money you spend is equivalent to the performance gained. They are not proportionate to each other. 
Actually I had the then top rated in its price class Tekton Lore Reference speakers and I assure you the Harbeths at 4 times the price that I replaced them with, and the Magicos at 24X their price are substantially better.  Better in audio is a diminishing returns proposition always. There is no way any Tekton can compete with the class of speakers WC is listening to.  Sorry but as much as we would all like a 3K speaker to kill these 35 to 80K speakers it’s not going to happen. 
 And while on the subject of Rane would you really want a $600 piece of anything in your audio chain when WC is agonizing swapping probably 1 to 3 thousand dollar each power cords and Cables? Really? And you keep bringing it up?
I'm in total agreement with taking out the resonance of a piece of equipment. My Schiit Freya tube preamp is improved a lot with putting it on spikes. Now solid as a rock, keeping the 4 tubes and electronics without vibration.
Also as mrdecibel has described, good power supplies and discreet components are tantamount to having a solid analog output. I have the Audio Alchemy DDP-1 Preamp/DAC. And there is a power supply upgrade (Alchemy PS5 $599). The thing weighs 9 pounds, and is a game changer. Here is an explanation of what a good power supply can do (Alchemy PS5). There's no denying the importance of a properly designed power supply circuit.
"Inside the PS-5 are two separate, regulated power supplies: one for analog circuits, the other for digital and control circuits, which provide each the unique power qualities required to maximize their performance. These discrete supplies are routed into the DDP-1 (DAC/Preamp/Headphone Amp) through a special multi-pin connector on the rear of the unit for easy connectivity. Additionally, the AC-to-DC conversion is performed inside the PS-5 to prevent interference with the sensitive analog audio circuits inside the DDP-1. A balanced supply with separate analog and digital/control feeds, separate positive and negative rails for analog circuits, and large banks of storage capacitors for better filtering and improved dynamics."

In reference to the RANE EQ.... I think that EQ works. Some systems will sound dramatically better, and be absolutely necessary with some rooms. You could have all the best equipment, but the room or synergy of components are holding you back. A good EQ will bring the music to how it was intended to be, and it will be wonderful. I personally prefer an analog EQ like the RANE over digital EQ. I have not tested the  miniDSP SHD Series, but it could be a game changer for DSP. I know that the company is at the bleeding edge of DSP technology. Here is a link https://www.minidsp.com/products/streaming-hd-series/shd-series
Hope this helps. Not everyone has the perfect room.


IME, home eqs ( such as a Luxman you mentioned previously ) might measure better than the Rane, but they have inferior circuit board layout, inferior components, many non discreet components ( chips ), and a much smaller power supply. Admittedly, the units are very resonant tin cans ( as most all pro eqs ), but I took care of that. Enjoy ! MrD.
Say what you want, because I can guarantee you, dguitarnut, that you never used the Rane ME60 ( or a pair of ME30s ) as a line stage, in place of a 5K line stage preamp. And if you did, you certainly would not be making the comments you are making. As far as Tekton, I never heard the DIs or above, but am aware that there are many individuals who have changed from much more expensive speakers to Tekton, stating their greater listening enjoyment. And, those that upgrade, stay with Tekton. Once again, opinion, which I appreciate, and makes these threads interesting. Enjoy ! MrD.
The Roon parametric equalizer is perfect if you need equalization ......not some decades old mid grade sound stage gear.  Might as well throw in Teckton speakers into the conversation too Lol.
Yeah......you don’t need that Veyrun when you have a Dodge Challenger in the garage. 


@gtaphile...viber6 owns the Rane, in place of a high quality line stage preamp, and his ears, system, experience and welcomed commentary here by wc and others, have no problem with it. I too have one, and it was viber that created my curiosity to pull it out of the closet and give it another go. Was not bad as a line stage. I modified mine to eliminate all of the chassis and circuit board resonances typical with pro eqs, and to me,  made a huge improvement in sq over stock. I have had many eqs in my day, and the Rane is special, imo ( in use only as an eq ). BTW, Rane is the company that developed the " Interpolating Constant - Q filters ".Turns out, in my main system, I still do not need an eq, and prefer my Luminous Audio passive unit, but unless you tried it as a line stage, you have no right to request the " block the word Rane " from here. As I said, no one else has the problem you do. Besides, this thread has a lot of talk about equalization as of late. Enjoy ! MrD.
Someone please block the word Rane from this thread. It has no place in this discussion. Is there some click pay system for that word to the author?
Enough already!   
  
So guys, I removed 2 cabinets that were behind the panels And the highs are way different now. They have more detail and sparkle. Time... I’ve said it, seat time. Now I need to now get ready for the wife to come to me and go off that there are 2 cabinets in the middle of the living room that I need to put back where they were but I don’t know how to tell her I don’t want to... I may end up sleeping inside the crates of the Neoliths tonight. 
The Cars: Dangerous Type....the last two minutes of the song crank it up and follow the changing drum lead..the drums are all over the place bouncing around and slapping my brain!!
be patient .a lot of good stuff on all of those I mentioned.... should be really good on the Neoliths
   The K &D sessions will blow your mind
Try some Bela Fleck, Keb Mo’, Jing Chi, Melvin Taylor and the Slack band ( He will be standing in front of you )
Huge Soundstage on that one 
Try that Ayon Audio Cd I sent you. .....crank it up :) .
It has a lot of good ones .Tin Pan Alley (SRV) ,Bela Fleck, ETC.It is Worth a listen
Mushroom Jazz 6 for sure
Oh You Absolutely MUST hear the Kruder &Dorfmeister K&D Sessions .Then... Cranked UP
I sent it to you ... so you have it
Also that Nightmares on Wax should be really good .. gotta crank it a bit !
I would also concur about electronic music with Martin Logan. The absolute speed of ESL panels show off "big time" with that type of music. If you have proper bass too....... OMG. Take that dynamic woofers and tweeters!
Next tweak will be to remove any cabinets behind the Neoliths. I want the walls behind the speakers to be empty with the exception of the tv. 
Greyhound: Diana Krall, Karen Souza, Sarah Mclachlan, Santana, the cars, lynyrd skynyrd, etc etc etc. 
How do they sound? They sound best with electronic music with tons of bottom end. Think deadmau5, tiesto, Calvin Harris, etc. That type of music sounds like I’m at the live concert. Incredible to say the least. 
Something that I have noticed with interconnects (XLR/RCA) and speaker wire is that SILVER can be too much of a good thing, and brings out more treble and makes it brighter. I'm still a believer in COPPER with silver soldering at connections. To me, the sound is fuller. And it brings back a bit of the analog balance to a system, especially using digital files. Too bright a sound is just not the way the artist has intended for you to hear their music.


Currently I am using Morrow Audio MA5 XLRs (mid level) and Morrow Audio MA5 SPIDF from my Tascam CD Transport. I feed USB from an Audioquest Diamond cable (15ft) to a USB Bridge (femto clock system) Singxer SU-1. The Singxer SU-1 is a very much needed upgrade for USB coming from a computer. My connection from the USB Bridge to the Audio Alchemy DDP-1 DAC is thru AES/EBU (also Audioquest Diamond cable). I cannot over stress how much the USB Bridge Singxer SU-1 opens up the sound with superior femto clocks. Took my system up the audiophile chain in spades. I see many of the top DACs now with a Femto Clock system box ahead of the actual DAC itself. The stuff just is a game changer.


Now speaker cables are something that I want to explore in the future. Currently I'm using 8 gauge twisted and stranded OFC Copper cables that I have terminated myself. I have used these cables for many applications in the past, and find that the strong current of my Krell amps mate quite well. I have seen speaker cables overheat with not enough gauge. Within the next 6 months, I am going to try the Morrow Audio speaker cables. They are many strands of thin insulated solid copper wire. Depending on your budget, you can get 432 solid copper wires Morrow Audio SP5, or for some more cash 864 solid copper wires (SP7 model). Once broken in, the sound is up there with the expensive cables. There are also Grand Reference and 10 year anniversary models of this solid core insulated copper for the large wallet types.


I'm hoping that the speaker cable upgrade may bring up another notch of great sound. I just love Morrow Audio XLRs, I can tell you that they are perfect for my system. Worth a shot at under $500 for a pair with their coupon and a set of old cables that I would send to them for a lot of money off.
spinaker01,
Does the Roon do EQ in all freq?  How do I find out about the Roon?
I agree that it would probably help (Rane) but i use the EQ in JRiver Media Center which works very well. I mostly leave it flat, but when needed i can adjust
grey9hound,
I totally agree.  Speaking of cost, although you are pleased with your sophistcated room correction system, you can achieve much more in the entire frequency range with the cheap Rane ME 60 EQ at $200 used.  Maybe its analog circuits are technically cruder than digital, but it is so infinitely flexible that using only your ears as a tool, you can achieve wonderful results.  Even though I have promoted objectivity in certain areas, ultimately we are out to please ourselves, not write a PhD thesis or file for a patent, etc.
I am curious as to what songs or Artists have you played on the Neoliths .
Have you tried all kinds of music ?
Anything that stands out ?
Surely you have played much more than just Dire Straits?
Do they sound good with all kinds of music or are they suited to certain types ?
grey9hound: so what you are saying is that if you have a Bugatti Veyron in your garage right now, 16 cylinders, $10,000 for an oil change, $50k for all 4 tires, etc, etc, you then would be ok going to a Honda Civic with a turbo engine because the tires are cheap, it puts out 700 hp hp, and it can also go 200mph per hour like the Veyron right? (although it would take the civic about 3 hours to get up to 200mph)
Nobody said expensive stuff is what is needed. I simply said that this speaker needs quality amplification and through my experience with many amps, these amps are never cheap. It was only implying that these speakers take quality amplification the same way a Porsche GT needs the crazy expensive tires to be able to go what it does or else you will be spinning tires each time you put the pedal to the metal. I am somewhat "spinning tires" right now until i try more current, more wattage. I tried this exercise with the vividi audio g1s already. 
WC, 
Although playing with spikes, tilt, powercords is useful, the most important thing you have done is tone controls.  I can illustrate why use of more flexible EQ either analogue or digital will give you much further enhancements by giving a numerical analogy.  1 is the worst sound such as barely perceptible music from a distant analog radio station with 90% distortion.  100 is perfect live sound from the best seat.  Nobody has achieved 100 in their audio system.  With the world's best (WB) preamp and power amp without tone controls, you can only get to 40.  Call the best DAG preamp and power amp without tone controls 38.  Your Momentum integrated without tone controls used is 36.  But with the tone controls the way you like it you are now a giant 14 ft basketball player with double the height and double the audio level at 80.  In other words, there is no WB amp and preamp without tone controls that can equal what you now have..The tone controls on the Dag are rudimentary but still good enough to show you the absolute necessity of them.  The tone control circuit is another circuit, so even though that is a minor disadvantage, the benefits vastly outweigh that factor.  With a much more flexible stand-alone EQ there is admittedly another circuit in the chain, just as with the Dag integrated, but the ability to fine tune the tone control is of extradordinary benefit.  If you like tweeking now, just wait until you try a dedicated EQ with the WB preamp and amp.  Then you will achieve a 90.  When you build a larger better room, the EQ settings will change.  If you listen to a quieter piece of music where you don't need much of the additional gain of a preamp, you can use the Rane with its 6 dB gain from balanced inputs/outputs with only the WB power amp, and achieve a 95.  How about that?  Maybe the digital EQ's are better, and then you can get more.  Exciting!!
@whitecamaross you are obviously hung up on how much something costs.
Lots of amplification does not have to mean expensive.
Why are you so hung up on cost.you always state that upfront.as if it means everything...it doesn’t. Many here have tried to express that to you..but you don’t get it.
The Tekton speakers from 3k to 12k will come much closer ,if not surpass what you have tried at much less cost.
Read the reviews. At least 7 or 8 reviewers at
Stereotimes own the Tekton encores or ulfberhts as their reference speakers.
Lots of other speakers and amps out there that perform as well or better than what you have or have tried for much less!
Cost does not = performance!
Maybe someday when you are more experienced you will understand it.
Maybe ..???
Review #1 from audioholics:
Pros
  • Superb bass extension to die for
  • Huge soundstage
  • Exquisite build quality
  • Ability to fine-tune bass and crossover in the speaker
Cons
  • Expensive
  • Huge footprint
  • Require lots of amplification to make them sound their best
  • Require a medium to large room


Review #2 (mine)

  • The very best bass i have heard in my room EVER by miles and miles and miles. Did i say i could play the magico and wilson audios all at once ( 4 speakers) and STILL they won’t even come close to the fullness of this speaker? It makes the bass from a wilson or magico sound mediocre.
  • Huge soundstage: extremely big sound with a level of imaging i have never heard before
  • Build quality that no other martin logan speaker has ever had.
  • VERY EXPENSIVE
  • Huge footprint, but not as big as some may think. i actually feel like the vivid audio g1s looked just as big
  • Requires lots of amplification? this is an understatement. i have zero doubt that they will require the best tube or class a amps you can afford. Dig deep into your pockets and pull out every single penny you have.
  • Possibly harder to place than the vivid audio g1s. These speakers "talk to your room" unlike any other speaker.
  • Watching a movie through these is like being inside your tv. Things just pop out of the speaker in all directions.
  • As big as they are, they disappear and you remain focused with what they present between them.
  • ZERO FATIGUE of any kind at any volume level. i cranked them up yesterday to close to 100db and it sounded as if a 747 was taking off. Oh, i also dozed off while they were playing for hours at loud volumes. My ears remained comfortable no matter what the volume was. 
  • They tend to sound their best when cranked up (could also that they need either a class a or tube amp to sparkle more)
  • If you love Beryllium tweeters, this speaker or any electrostatic speaker may not be your cup of tea in regards to the high frequencies (they will sound warmer) No other speaker sparkles as good as Beryllium tweeter does. However, If you love soft dome tweeters, this speaker will reward in ways that soft dome tweeters can’t.



I've heard the same years back with panels and connecting the power straight into the wall. Good catch!
I'm interested to hear what you have to say about the Block amps. Also, did I read somewhere that you may try the Ref 250 mono's? I read those are one of the best AR amps ever and with the SE upgrade. I've listened to its little brother the Ref 75 SE and was very impressed with its sound and its power for just 75w. I was thinking if I ever go tubes for power that the Ref 250 would be the place I land. Although, all your talk about the Luxman combo C900/M900 has me really wanting to try that gear out.  There's a dealer in Chicago with the little brother M700 offering me a decent deal to try it out. I just have a hard time letting go of my Plinius Class A power on my B&W 801N's......Keep up the testing and listening!

On the topic of digital EQ, I have to say that I’m a relatively recent convert to Roon but now a big fan of the digital EQ offered. The parametric bands and controls are very flexible and introduce much less time/phase/distortion artifacts  than any analogue EQ - and significantly less than an old Rane unit designed for semi pro use. Try going one step further and getting a decent measurement mic and REW software. This way you can “see” what room/speaker  issues you have and you can then use this data to guide you for placement of the Neoliths and any possible room treatments. Then you can introduce compensatory curves through the Roon parametric program. This at the very least, brings some scientific methodology to your process and provides some repeatability to your efforts. Even if you determine that a “flat” sound isn’t to your tastes, you still have a reference baseline that you can then overlay your preferred palette to get you one step closer to perfection. You can bet your speakers weren’t design solely by ear, why should you be content to set them up without the benefit of a scientific prochess?
Ok so this is an update for those of you who own panels. DO NOT connect their power cords into any power conditioner. I had both connected to my p20 and I just unplugged them and went straight into my 20 amp outlets and the change was noticeable. The sound became larger and almost like it wraps behind my head. I also tried the Wireworld silver 7 power cords with the Neoliths and I feel like they don’t work well. The Neolith come with some aftermarket powercords and they seem to focus better. 
This is getting interesting. The more I play with cables, the more I can hear things change. 
Good to see that you are using the spikes. Tilting them down, a no brainer. The resulting sound is usually very noticeable, and put the whole bottom end in line with the speed of the mids/hi. You are just scratching the surface, I feel of what the Neolith is capable of. I would be curious as to what Piano and also Acoustic Guitar sounds like with these babies.


If you have a Tidal account, I have found that some of the latest recordings coming out recently are much more cohesive than the older recordings from the past. They sound so much better. This has led me to explore the Tidal catalog and discover all kinds of artists. And the tracks really bring it home with my ML electrostatics.   Vocalists have such a good sound with electrostatics, compared to conventional dynamic speakers. Going up in pricing for dynamic speakers changes that. But those types of speakers are crossing into the 50k or more club.

good to read that you are enjoying the ML to date. As above, more hours and work left to do. Several weeks, at the least, are required for these speakers to "bloom". Enjoy the journey.


Happy Listening!

Got it. I’ll let them play until block audio arrives.
Update: i spiked the speakers and tilted them forward and I noticed the bass became tighter and better imaging.

Hello WCSS, with 5 days of use on them, the Neos are likely pretty tongue-tied... No wonder they seem to be treble-shy... Let 'em cook for some three or 4 weeks on end... I'm pretty confident they will bloom. Once they stabilize, that might be the time to find them ideal equipment matching, if any alternatives were required at all.... Before stabilization, you'd be chasing an ever moving target.

Do not get discouraged MrD... There is enormous value to everyone in reading your opinions in this thread.


My question to WCSS,,, How many hours of break-in do the Neos have... My concern is that right now you might potentially not be hearing what they are really capable of... And by prematurely fiddling with various components and cables in the audio chain you might be overcompensating for temporary Neo artifacts that will abate with time.


Saluti, MrG

 

WCSS, You can also use a software based DSP program to contour the Neoliths to your liking and use any preamp/amp combo.
@mrdecibel 
dont stop posting. Any help or feedback is read by me. I may not respond to everyone here because I’d spent many hours of my day but I’m reading everyone’s comments/feedback. 
The Neolith is just a huge monster that needs more attention than I anticipated. I can honestly say I think I know why some people didn’t like this speaker when they first heard it. It is so faithful to the recording and so dependent on everything else connected to it that it will kill your hopes and dreams if you don’t obey what it needs. I am simply trying to get somewhere better with it by trial and error. I’m in no rush to make a decision. Yes if I can’t make them sing then I won’t ever buy panels again and will focus on tweeter/woofer speakers. 
Every single review I’ve read always states they need a lot of power to sound best. I gotta be fair here and do that plus spike them which will allow the panel to sit about 1.5 inches lower to the ground and also enable me to tilt the speakers forward in order to create far better imaging. My ears are about 37-38 inches off the floor and I’m about 8ft away from the speakers. This is making me think that I’m probably sitting too low which is why I’m not getting what I should be getting from them either. 
Still a lot more to do here.
