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!
For the time being here is another report on the same show of the Magicos A3 you said sounded like garbage from other sources. Yeah maybe not in the same league as the 50K and up speaker level you have been listening to but they shouldn’t be slammed because they are entry level for the masses to high end audio. https://parttimeaudiophile.com/2019/03/17/florida-2019-magico-luxman-audioquest-critical-mass-system... |
I ordered a new dac from lampizator. It will be here in 3 weeks and it will have the new Kr242 Richard kron tubes. It will also be fully balanced. Im currently using the momentum integrated with Nordost Odin speaker cables and powercord. My dacs are the oppo 205 and the simaudio 650d. Im going to leave the block audios off to the side for the next 2 weeks along with the ref10. I want to give my ears time to get more acquainted with the momentum. Once the lampizator arrives then I’ll bring back the block audios and ref10. I’ve playing with Odin 1 powercords and Shunyata alpha NR. My feeling is that Shunyata adds more bottom end and the Odin more detail and holographic presentation. I would say that I prefer the alpha nr pcs in the Monos rather than Odin 1. The Odin 1 seem to do amazing things with sources and preamps but adding the shunyata to the amplifiers seems to add the fullness which rounds out the presentation. it adds more “meat” which makes everything more enjoyable. |
All, i have ordered a brand new, fully balanced lampizator pacific in gold color. The unit will come with the new KR 242 tubes (Rk edition). I was told by Fred from lampizator that these aren’t your typical 242 tubes. These are tubes that the Richard Kron just manufactured for lampizator and they just started to ship these tubes as of a month ago. According to Fred, they are dynamic, more detailed and have more gain Than the 300b I had. I was told I need to wait about 3 weeks for it to be built. I believe this will probably be my new preamp. I would be shocked if I stay with the ref10 as my preamp after this new dac arrives. |
bigddesign3, OK, I understand your needs. For casual but attentive listening to the radio off axis while I am eating, I listen at much lower than live volumes. To get better clarity, it helps to boost the HF when they are rolled off by listening way off axis. At low volumes, the HF boost is not irritating. Cheers to you. |
viber6, I was pointing out to be careful that you don't mess with the highs so much that you get too much of a good thing. I love to blast my music at times, but my family will only tolerate so much of the whole house in an earthquake with my electronic dance music. So I try to only do that once a week or so. I love most all types of music, and some can be turned up quite a bit for a few minutes. My Krell KSA-200S is a real gem with having the current available to set off some "holy sheet" moments at high volume. But most listening is done at respectable levels. My music listening goes all the way from the 60's to now. If it sounds good, I'm ok with the type of music it is. There is not a music type that I like more than another. I'm quite good at picking out the tracks (ahead of time) that will play on the radio, and become hits. At 62, I still get excited about new music coming out. My only regret is how much money I have spent to get to where I wanted to be with my retirement home system. It does sound exceptional though. Cheers. |
bigddesign3, Good. Also, imagine that you have a perfect system that reproduces live unamplifiied music indistinguishable from live. At the live volume, there are plenty of highs and every other sound attribute, and if you play your system at the same volume, both the live sound and your reproduced sound are pleasing without harshness. But if you then crank the volume of your system higher or get too close to live sound where the volume is too loud, there will be harshness in many areas, not just the highs. This should not be a justification to reduce the highs in a system just because you want to blast it louder than the natural live sound. Perfect reproduction involves the usual goals of balance and information retrieval, and also the proper natural volume, not blasting. |
bigddesign3, I think you meant that one shouldn't give Martin Logans too much ENERGY in the highs, not too much CLARITY. It is fine to prefer a more subdued tonal balance with less highs, but clarity must never be sacrificed. Music is a type of language of sounds and words where clarity is paramount. Also, if you look at a classical music score (printed music) there is so much information present that no hifi listener has yet heard because all systems are veiled and lacking clarity to some extent. |
I brought out the momentum integrated back from the dead and used Odin pc, Odin speaker cables and oppo as a source which is also using Odín pc. Man this sounds far better than I remember hearing it before. Gorgeous mids and smoothness. I don’t get any ear fatigue but the highs might be a tad “ disorganized” when cranked up to high levels. Could be either that the momentum Is clipping or that the oppo 205 continues to feed me highs that are a tad bright when pushed. greyhound, you could be right about the brightness :) |
A friend came over last night and we listened to different types of songs. He did not know which speaker cable was playing as music played. He chose the nordost each time without knowing. His words were: “The shunyata sounded muscular, bold, in your face and the nordost had better highs and detail without so much bottom end fullness, more natural” We had odin 1 on the ref10 and oppo. That said, when we cranked things up, we felt that the odin combination had a tad too much brightness. You almost couldn’t hear it loud for a long period of time. I proceeded to take off the Odin 1 from the oppo (this is the newest cable and probably still breaking in) and used a shunyata alpha nr on it and it helped tame things down but what I’m now needing to find out is what will give the best results: 1. Using odin pc on the amps and preamp and not on the dac 2. Using one shunyata interconnect in the mix rather than platinum 8 which is what I’m using to go from the dac to the preamp and from preamp to the amps. Maybe swapping on of them out for the shunyata would help? 3. Could it be that the Odin 1 being used one the oppo is still too new and still breaking in which is why I can hear some slight brightness at loud volumes and the system is letting me hear this? 4. Last but not least, I may need to reposition my speakers and try to toe them out in order to decrease some of the brightness I detect at loud volumes. As you know, electrostatics allow you to do this by playing with the toe in. Many different scenarios. However, the system is coming into its own specially at moderate to low volumes. |
WC, Whichever speaker cable is the winner this weekend, spend ONE DOLLAR or so on zip cord. Buy lamp cord at a hardware store, etc. You will find it to be more focused, tighter, clearer by a mile than any fat speaker cable you have tried. Bass will be tighter and more revealing, even if it doesn't have quantitative oomph. Your buddies should drop on the floor when they hear what zip cord does, in a blind test, against preconceived prejudices against it. About a month ago, we discussed this, and none of the technically knowledgeable people here could provide convincing explanations about why thin zip has these characteristics. In contrast, I have found that many power cords have better clarity than stock cords. So I am not surprised about your findings about Odin power cords and speaker cables. |
Quick Update: the wife prefers the Shunyata speaker cables with the odin 1 powercords than the odin 1 speaker cables. she said, and i quote: "they sound more real like the singer is in the room with us" i have a few people coming over this weekend to do a blind fold shootout of the odin 1 speaker cables vs shunyata. |
This "silver" or "copper" speaker cable is not an issue. There usually is a difference in sound like you state. I'm just pointing out a way of taking a look of what the recipe may bring with "copper" speaker cables. I don't like overbearing highs with digital playback. Therefore, I prefer a bit of ease at the top of the music spectrum. Reminds me more of the analog days. Having tweaked the crap out of most things audio in life (a ton), I'm trying to give input on ways to see what's best. That's all. @greyhound, that's cool that you are a car stereo guy as well as me. |
Here is Toroid’s (Steve Schoonover) perspective on Silver Vs Copper. He is/was the owner of Superior Mass Audio. They made a cable called "The West Star". They hand built cables from the mines they own or owned. It seems that hey are no longer in business, but he does talk about Silver vs C101 Copper. Our family owns mines in New Mexico. Working with the different elements and experimenting If you have to unscrew the RCA barrel to open up the This is why the best speaker crossovers are hand built and point I agree with Green, unscrew the barrel or just chop the whole Getting back to reality, silver vs. copper or a blend, in my 27 There are to many variables in the audio chain that can lead me Good luck and always remember, your ears! They do the final judging. An ardent audiophile’s perspective. The link below is to the specs on the West Star Copper cables : VERY INTERESTING.IMO 952 Feet of twisted pairs. It seems that it took that many to get rid of the "skin effect" https://www.audiogon.com/listings/speaker-superior-mass-audio-the-west-star-sma-since-1998-2014-09-1... |
WCSS, I think I remember that you liked the copper Wireworld 7 over the silver Wireworld 8. Just a thought to check out the copper ones. Sometimes full copper makes for a fuller sound from top to bottom. Silver tends to make the highs stand out more. In the end, a good cable will not bring ear fatigue over a short period of listening. With these new Nordost Odin 1 power cables, it looks like you are getting a spike already with the mids to the highs. A balance may be needed in order to get the sound you are looking for. Just a thought. Wish I could be there to hear these Neoliths. They are just starting to show what they are capable of. |
Eclipse line is in both speaker cables and interconnect. WC has the Platinum Eclipse 8 speaker cables. Platinum Eclipse 8 is their top of the line, then Silver Eclipse 8 , then Gold Eclipse 8. http://www.wireworldcable.com/speaker-cables.html#quickcomp_speak http://www.wireworldcable.com/audio-interconnects.html#quickcomp_inter |
Gentlemen, i plugged in the second Odin 1 powercord into the system and now the ref10 has its own nordost Odin. This Cable is used so it has miles on it and within the first minutes of playtime, the sound DRASTICALLY improved. I don’t know what they put in these cables but wow. The nordost powercords are just KINGS. Far far exceeding my previous cables. What a spectacular powercord. I’m in shock to say the least. |
Grey9hound, Thanks for the article. Makes sense. Still, I find relatively small subjective differences after break in, with components and cables. A big exception was the Nordost Frey 2 XLR interconnects, which were crystal clear at first and then became comparatively blurry. My Nordost Frey 2 RCA interconnects are still wonderfully clear and precise. |
Hi WC, I have a quick question regarding cabling since you are on that topic. I'm proceeding with a purchase of the Gryphon Diablo 300 based on your suggestion for my B&W 803 Diamond speakers and subsequent auditioning (thanks for the tip), and am wondering how big of a performance delta I would expect using Valhalla 2 PC versus something lower end like an Audioquest Hurricane. In another thread some are saying that the difference using any cable won't be that different from the stock Gryphon cable, based on the Diablo's design? Not sure if that is true or not. Odin is definitely not a consideration for me (unfortunately....). I'm also considering the PC for my InnuOS Zenith MKIII streamer which I've ordered. |
Wireworld Platinum 8 xlr vs Shunyata alpha nr xlr: 1. Wireworld platinum 8 has monstrous soundstage making the shynyata sound narrower 2. Shunyata has great overall balance. Nothing really missing but as soon as you change to the platinum 8, the sound just opens up wall to wall. Looks like I’m back to wireworld 8 interconnects once again. I prefer their big wide sound. Odin Speaker cables are still not quite there yet for me. That said I need more time here in order to see what happens as I add more Odin pieces in the mix. Will I return to wireworld speaker cables? My heart says I probably will but I want to convince myself that there’s a reason why nordost Odin speaker cables are so much money. There’s gotta be a reason but so far their speaker cables are nowhere near as impressive as their powercords. Time will tell what happens here. |
3 minutes into the listening session and the sound is somewhat slower with the nordost speaker cables which is the only thing I’ve swapped out. I also find myself having to turn up the volume higher with the nordost speaker cable for some reason as if these cables place a Bigger load on the amps. I have to let music flow through these cables for about 48 hours so they can settle in my system and then do a real comparison. I also have decided to use an Odin powercord on the preamp but I’ll do that later during the week. FYI, the only things running from the shunyata are the block audios and oppo. The preamp and speakers are plugged into the wall. i remember the Odin powercord not sounding good at all when I first plugged it in and then on the 3rd day I was hearing a crazy amount of stuff that blew my mind. Will this be the same for the speaker cables? We shall see... the fate of the Odin speaker cable will be known in the next few days. |
@whitecamaross Very interested to see how this goes. I've heard Nordost many times and do like their house sound. Mostly Frey2, Tyr 2, Valhalla 2. Have heard Odin 2 once or twice. I have a new system and will be working on power cords next along with power conditioning. And I've been looking at Shunyata Research and their NR line of cables along with Nordost and will probably look at least at a few other brands and then try to demo a few and make a choice like you are doing. It will be very interesting how the 15X Odin 1 fairs against the Alpha NR. I'm not sure that that will be a fair gun fight (only based on price delta) but wouldn't it be amazing if you find you like the SR stuff better?! Do you have any power conditioning? So I guess you have had the Nordost stuff on the Vidar? I need to talk to my dealer about that. |
