Powered speakers show audiophiles are confused


17 of 23 speakers in my studio and home theater systems are internally powered. My studio system is all Genelec and sounds very accurate. I know the best new concert and studio speakers are internally powered there are great technical reasons to design a speaker and an amp synergistically, this concept is much more important to sound quality than the vibration systems we often buy. How can an audiophile justify a vibration system of any sort with this in mind.

@lonemountain ,


It is one area where we think the ATMOS standard / specification is insufficient and lacks the framework for future extensibility, tuning, and features.

ATMOS provides a rough definition for the dispersion pattern of speakers depending on where used, but it is fixed, without consideration of actual pattern, cutoff, dispersion versus frequency, etc.  For an extensible object oriented speaker system, there should be much better ability to define the speakers and eventually the appropriate algorithms to maximize the "experience".   Though ATMOS is object based, those objects are assumed to be fixed in terms of what they are with a fluffy definition.

@thespeakerdude 

It is one area where we think 

You are stepping into an area that borders on fiction. You have NO system any one is aware of, no creds, and now "we"? Is we invisible too? Post a link to your think tank.

ATMOS provides a rough definition for the dispersion pattern of speakers

Really? You actually have an Atmos system that isn't invisible??? Details? Is this something you read about too? LOL.

eventually the appropriate algorithms to maximize the "experience".

When you have some pics to post of your atmos system you will actually have an experience, it should be better than a chatroom I hope.

RE: the Atmos "experience" you can’t blame the speakers, the content, or the mix. If your experience sucks you can change it, now, easily.

I use "technology" to change a meh Atmos experience.

Speaker setup with dolby specs, auro-3d specs, or DTS-X specs? check.

Room measurements optimized with acoustic treatments and dsp? Check

Appropriate "upmixer" selected based on the content? Check and double check.

( If your upmixers are sub par check out Auro-3D, Dolby Surround, DTS-Neural X, Sony 360, THX Spatial Audio or legacy upmixers like Audyssey DSX and DTS-Neo-X. If you want more upmix profiles to choose from check out a Yamaha, or Onkyo products which have proprietary codecs. The Logic 16 upmixer from JBL and Arcam products is supposed to be wicked but I haven't tried))

For those of you who are "imagining" what it will be like one day to have an atmos system check out the other threads on atmos here. Or I guess you can keep making stuff up as you go along if you have nothing else to do 🙄

@thespeakerdude , in order to pass a "test" you would need to actually have a stereo. If you want advice about what to buy, please start a build thread. If not, please stop bothering people who actually own gear with your opinions which for all any one can tell, are just made up, cut and paste, from various websites.

 

Most of the DTS professional documentation is business-business only (and NDA) so I cannot post it here. The Dolby Cinema specification is here:

 

https://professional.dolby.com/siteassets/cinema-products---documents/dolby-atmos-specifications.pdf

 

I won’t say that Dolby rushed the specification, but like all of us, they have time to market pressures and first to market pressures. While ATMOS may be object oriented, the rather fluffy speaker specifications including fairly wide dispersion for some and very limited in terms of detail cutoff specification places limits on how many useful objects you can have.

There is also another significant limitation at least in conceptual implementation. The basic premise of ATMOS is that everyone will hear the same thing. That is fine for music,sufficient for mainstream theater, but lacking for where the largest entertainment industry wants to go, namely video games. Another expected growth area is immersive experience spaces.

There are obviously ways around it (headphones and custom software of course), but industry likes standards, because standards bring down costs, reduce training time, and improve time to market, and reduce risk.

@thespeakerdude 

I just said that all you do is cut and paste from the internet, and your response was...to cut and paste that dolby link from the internet.

I wish I was making this up but sad to say, you have been exposed.

Ok @thespeakerfude @kota1 I have a test for you both. You have seen my home system (Not the mixing system) and I have a chance to give it a $200k upgrade, I love the high and mid that Im getting from my main 9hs I love the bass I'm getting form my JL 113 subs (but I really hate but buz) I hate the noise floor of my PS Audio  BHK preamp, love my surround speakers. I don't want to mix and match equipment all the time I'd like to get really good non tube amp equipment with a very low noise floor that I can keep forever. The stereo part of the system must be top notch. I what would you guys do with my sound system. You both know how I feel that a system should work together the Steinway Lyngdorf systems are the perfect example. I do want tube sound without the stupid tubes. Thanks 

@donavabdear

First, thanks for the shout out. This is not the thread for a build. What I would do in your shoes is start a build thread and get contributions from the entire community here. Asking for "tube sound" without tubes is going to depend on the "tube sound" that pleases you. Then it has to be a "tube sound" through your speakers. I do know of one solid state amp that had a switch on the back for either tube sound or solid state. Would the sound please you on your Paradigm speakers? Who can tell.

I have tried various amps on my passive version of the Paradigm Studio Reference speakers. There was one amp that when I connected it in bi-amp mode threw the most incredible wall to wall, floor to ceiling soundstage. The Carver AV 505 THX certified amp. This amp was a precursor to Bob’s next company Sunfire where he took the power supply technology one step further by adding two types of connections, voltage and current. (See Robert Greene’s comments in 10 Most Significant amps of all time)

Here is a page of reviews from owners of the Sunfire Signature amp:

and here is a link to the manual, see page 13 about the voltage and current source connections.

 

From Steve Guttenbergs review:

A unique connectivity option appears on the amplifier’s main left and right speaker connections, which are labeled "Voltage Source," and "Current Source." Over my Dynaudio speakers, the Voltage outputs sounded more detailed with better-defined bass, while the Current connection definitely shifted the balance toward a bigger, fatter, more three-dimensional sound. So, the TGA-5400 took on some of the sonic personality of some audiophile tube amps.

The MCH amps have this feature too but you will have to find them on the second hand market.

If you are looking for the Sunfire look for the TGA 7401. If you bi-amp your 9H speakers with the voltage source to the woofer and current source to the tweeter (the 7401 is 400W a channel) that would be 800W per speaker I think you will be a happy camper. Your speakers are rated to 500W but I don’t think they will have a problem with this amp. You will have 3 channels left over for your CC and your surrounds:

 

@donavabdear ,

 

I am not up on all the latest in home audio equipment to even begin to spend $200K, and it would definitely take a good review of the space, understand what potential acoustic issues there are, etc.

However, before throwing out the baby with the bath water, maybe we need to change the water first?  One comment on the tubes, I am not an expert on them, but I thought the tubes in pre-amps or pre-amp sections could last 10 years? That does not seem like much of a hassle if you like the sound.

Just a quick perusal. You only have a single left and right balanced output, which I assume is going to the amplifier? What are you running to the sub? One of the unbalanced outputs? Those are not the quietest outputs, but not the worst.
 

- The amplifier gain (Stereophile) is high and you can't control it

- The noise on unbalanced outputs of the preamp is high, but looks like about 90db on the balanced. Not solid state, but not awful

- The output level of the preamp is high (and looks like that may be where the SNR is done)

- You probably have a ground loop to your sub. Isolation transformer to power your sub, audio isolation transformer to isolate the single ended connection if that is what you have

- With the amp gain so high, you need to gain up your sub to match, making the buzz/noise worse.

 

Your amp is MOSFET output, so it won't behave like a regular tube amplifier with output transformers and tube amp output resistance. I think that is what that Sunfire was trying to emulate. Maybe its the distortion of the tube preamp you like, maybe the tube section of the amp, maybe the two together, or maybe something completely different.  I think I would start with a new SS pre-amp with lots of balanced outputs including one for the subs/mono and preferably one that lets you set the relative outputs.   With your budget, I am sure you could get a loner.  I would start with something with really low distortion and noise floor. Maybe you will like it, but at least it will give you a baseline.

As for the $200K budget first check out the Sunfire amp to see if you get the "toobie goodness" without the tubes. After biamping the 9H’s use the current source connections (at 400w a channel) on your CC and surrounds.

Please start a build thread for the rest, not really appropriate for a thread on powered speakers.

Review on the Sunfire 7401:

The so-called "current sources" with big internal resistance modulate the work of a tube amp. But you can switch to Voltage Source connectors - in this case the amplifier will work as a voltage source with minimal internal resistance and as a consequence maximal damping of the load.

We started the test with "current" terminals. The device immediately conquered by sonority and a completely smooth musical balance. It has a tremendous energy in the area of the lowest "seismic" basses and elaborates very well overhangs. But TGA-7401 didn’t surprise by absolute dynamics. Yeah, this device can provide a clear sound at the most powerful levels, but - without fiery temperament. The sound here is relaxed and open, rich and calm. It’s amazing but having such a phlegmatic character, the sound can’t be called slow. The device conveys the relief of drums accurately, deeply digs for each harmonic and is able to give copper, entrancing by its brightness, naturalness and beauty. It is really special. It’s hard to remember an amplifier from this price category, which not only gladdens by detailing but also by exceptional harmonic resolution in the uppercase. Each played plate is unique and inimitable in Sunfire!

An interesting metamorphosis occurs at switching speaker system to Voltage source terminals. Bass is slightly offloaded and accelerated, overhangs become shorter and more sharp, but the energy doesn’t weaken but as if brightens. Yes, the sound picture turns out to be less somatic, but more transparent and better detailed. This mode is good when you want to get the purest transmission of sound atmosphere as well as the most accurate scene.

@kota1, @donavabdear amplifier, the BHK300, is not a tube amplifier. It has a tube input stage. The output is a high bias MOSFET AB. The damping factor is 100. That is not very high for a solid state amplifier, but would be very high for a tube amplifier. The Sunfire 7401 is 150 in voltage source mode and 8 in current source mode. The Persona 9H drops to 2.4 ohms. It has low impedance dips at a few spots. That is not a speaker I would want with a damping factor 8 amplifier.

@donavabdear

Please start a build thread so we can get started, it should be a great thread when you see how many ideas you get from other members. I have some things I feel are KEY before you do anything. You have a dual space and if you get the mixing space wrong it will not only cost you budget, it will cost you income! See you in the new thread when you are ready but I recommend scoring that amp ASAP.

I admit my limitations as opposed to doing no research and recommending an out of production amplifier not suited to the system. Run that amp in the constant current mode and you would add new +/- 3db peaks/valleys to the frequency response that are not currently there

@donavabdear , creating a separate topic makes sense. Are you planning to add room correction to this system, or just keep it the way it is?

 

@thespeakerdude

@donavabdear ,

Clearly someone in this thread is out of ideas so is attacking the messenger here.

If you want toob goodness from solid state this is the best alternative I know. I have tried many Sunfire products (preamps, subs and amps) and can assure you it will be a quality experience. Whether or not it is "tooby" enough only you can tell. 

Re, the 7401:

 "...TGA-7401 is one of the most powerful multichannel amplifiers. The whole index of the device stands as follows: Theater Grand Amplifier 7 x 400 watts. Such return became possible due to quite clever system of tracking supply (patented by Bob under the brand Tracking Downcoverter). The idea is simple: in a common amplifier a high potential of power is constantly applied to output transistors, but in Carver's amplifier it changes in such a way that voltage allowance in reference to amplified signal is always 6V. But the realization of this principle is quite difficult because tracking must be performed with high accuracy and speed - a separate pulsed system answers for it. Carver created the amplifier, which almost can't be forced into clipping (our power supply had up to 800W on 47 Ohm), as output transistors always work in optimal and safe mode. The idea - "complex load" - doesn't exist for TGA-7401: actually it adjusts to any. In addition, lots of energy is saved, which went into heat before. " The inefficiency of conventional amplifiers results in accommodating the wasteful appetite by relying on massive transformers and other over-building to achieve about the same results, at more expense - and they really are limited by their thirst for more continuous power than any 15 or 20 amp circuit can provide. Read up on the patented Tracking Downconverter. Not only that, but a 20 amp power supply produces 2,400 continuous watts, and can produce several times that for very short times, though many times the length of musical notes. The patented Tracking Downconverter takes full advantage of this phenomenon, and is the only design that does. Another advantage is the Tracking Downconverter allows significantly lower continuous consumption of power, which is reflected not only in saving money on the amp itself, but also saving on the power bill, and therefor being a far more Green product through an advanced technology.

@thespeakerdude @kota1 

Thank you guys I admire both of you, you come at the problems from different perspectives. 

My BHK 300 amps have tube input stages and Mofset outputs that's the way it should be tube output stages is the weakest part of tube amps, tube amps with very few exceptions are underpowered but what they have going for them is the distortion sounds wonderful. Also if you use the equipment a lot the tubes only last about a year, and degrade from day 1, I'm really tired of it. I think a new build thread seems like a fun idea. I do have that Lyngdorf processor and I'm going to put it back in my home system without the PS Audio preamp and DAC. All outputs are balanced, I just took out a JL Audio CR1 which is an interesting unit that divides the low frequency to optimize for stereo and home theater, but with the Lyngdorf I can program all that. The PS audio equipment is surprisingly good for the money I have all top of the line equipment from them but I've heard more expensive systems that were not nearly as good as mine. Every time I listen to a SS system I think tubes would sound better, there is just a warmth that feels so good at the end of the day. I think I might look at some of the better systems in this group and copy theirs, I really don't want to have a bunch of equipment that is not designed to go together. Steinway is the only company I can find that designed everything together, but it so expensive no one has it and a few people who know say it way over priced, no one says it doesn't sound good. Thanks

Meridian is a company that takes designing things to go together to a completely other level. I have heard their gear (not recommending you change) and while expensive, it sounds great and is absolutely worth it IMO. In a thread on active speakers Meridian is up their with the best for my taste.

I look forward to your new thread.

It is funny how this thread has come full circle, it started with powered speakers being confusing. Now that has been resolved and it seems amplifiers are confusing.😵

@donavabdear  I don't know how the tubes in your BHK300 can only last a year, did you test them before replacement. They should last a good long time in an input stage.

@invalid I'm no expert on tubes but it seems like your right. The tubes on my BHK preamp have been changed a few times a year plus I've bitten on the scam for super turbo wonderful tubes that of course cost more, those tubes did seem to actually change the sound and of course changes can sound good but I spent a lot of money on my system to be at least close to accurate sound when I change to designer tubes it seems very wrong to put in a tube and from that point on it degrades. I just took out my PS audio BHK preamp and replaced it with a Lyngdorf processor and noticed more defined imaging and a big change in the noise floor, but there is a bit less wonderful warm and fuzzy comfort in the music. So frustrated.

Maybe someone out there has a fix for this. Another very frustrating part of the journey for me.
Crossovers and hi/low pass filters are the most misunderstood part of the audio signal. My home theater looks at the subs and just 2 speakers in a stereo configuration for music in a different way than for movies. There is an LFE track for movies that is separate than the low frequencies that are going to the subs and at a different low pass range. Also the satellite speakers are not all the same size my surrounds have a different crossover points than the speakers in the ceiling for surround sound movies or surround sound music. I did have a JL Audio CL1 that was designed for just this problem but it actually added more low and high pass filters actually convoluting the entire system. Also the passive speakers have crossovers inside the cabinets to optimize the drivers. Also there is electronic DSP that creates optimized curves based on information from the way the speakers interact with the acoustics of the room, these curves will most likely not correspond exactly to all the other curves our modern systems have in them and of course the microphone doing the DSP corrections is not flat therefore adding false curves from the devise that is supposed to fix all of this mess.

Pure stereo systems are great but the future is surround sound I think the winner is clearly Dolby Atmos but having separate systems for stereo and movies, music and cinema is a bit silly. There are other aspects of the audio signal that change the curve like phase knobs, separate EQ on subs, different pass filter fall off rates, built in EQ on preamps, A to D converters, D to A converts, etc. There is no way to have a modern music playback system that is coherent in any respect unless you have a system with 1 A to D / D to A converter and a good sounding room requiring no DSP. 

I have went out and recorded choirs with 1 very good stereo microphone (multi microphones always have phase issues by definition) and plugged that direct recording into an amp and listened on 2 speakers (also a phase issue). The result is like eating a fish that you just caught out of a mountain stream, it is an entirely different test and experience than when you buy fish at the market. 

No only are audiophiles confused but manufactures are confused because playback systems are not made like your ears, in electronics it is very difficult to not introduce feedback into the circuit for efficiency sake, so even at the base of a simple amplifier circuit we are already swimming upstream. Interestingly enough Edison when he was recording to a wax disk moving the musicians farther and closer to get the volumes right (mixing) he didn't have any of these problems, maybe that was the last phase coherent recording. 

@donavabdear

I think we are drifting off topic of powered speakers, if you start your build thread with the topic you just posted it would be better fit.

As far as separate systems I think your mixing system is separate yes, everything for your personal system can/should have the Lyngdorf processor and Paradigm speakers at the heart for at least the next year. If my income was linked to my mixing system I would optimize that first.

You have a flagship processor with flagship speakers and a flagship CUSTOMER (oscar winning engineer, right)= flagship performance, it should be pretty straight forward as you have everything you need (and then some).

Don't worry, this is NOT the "Titanic" 😁

@donavabdear ,

The microphones will be flat. They are calibrated when used for room correction.

The Lyngdorf should allow you to adjust the target curve. If you don’t find it warm enough, up the bass a bit, lower the mid-upper highs, and then adjust the mid-range to suit. You may get closer to what you like.

The imaging is likely better from a more consistent channel-channel frequency response and less distortion.

 

Also there is electronic DSP that creates optimized curves based on information from the way the speakers interact with the acoustics of the room, these curves will most likely not correspond exactly to all the other curves our modern systems have in them

The fundamental challenge in room correction is balancing these two conflicting requirements:

  • As close to a flat direct frequency response as possible, at least from about 1-5KHz, ideally from 200Hz - 6 or 7 KHz for each speaker
  • Consistent left and right channel room response
  • A room response that is somewhat close to the researched Harman room curve that seems to suit most people.

DSP can only do so much. You need to start with an acoustically tolerant space.

 

There are other aspects of the audio signal that change the curve like phase knobs, separate EQ on subs, different pass filter fall off rates, built in EQ on preamps, A to D converters, D to A converts, etc.

I wouldn’t get too hung up on this. For one, if you are using passive speakers that are not time aligned, the speaker is likely the biggest contributor. Two, many room correction systems will do time alignment. Three, reflections make a mess. Last, four, we are not that sensitive to phase changes. Well researched area. In design, our critical measure is always no phase discontinuities. You never want the phase to change quickly.

 

No only are audiophiles confused but manufactures are confused because playback systems are not made like your ears, in electronics it is very difficult to not introduce feedback into the circuit for efficiency sake, so even at the base of a simple amplifier circuit we are already swimming upstream.

Are you implying electronic feedback is bad? Poorly implemented amplifiers are bad. Feedback is not bad.

 

I have went out and recorded choirs with 1 very good stereo microphone (multi microphones always have phase issues by definition) and plugged that direct recording into an amp and listened on 2 speakers (also a phase issue). The result is like eating a fish that you just caught out of a mountain stream, it is an entirely different test and experience than when you buy fish at the market.

Is it real or is it Memorex? When I was young, and would go to clubs, I hated when they had a band and preferred DJ. Now I would prefer a band as long as they are decent. Does age hone our skills to detect authenticity? I have always preferred a well recorded live album, but that is not a simple stereo pair microphone. Untapped market for artists that are authentically talented?

I work in advertising - and during edits and voiceovers the best speakers I’ve ever heard were powered Genelecs. Just so damn accurate. I almost pulled the trigger on a pair three weeks ago. 

@snapoli2 if you do get the Genelecs absolutely positively only get "the ones" doesn't matter what model you get they are all very good. Genelec took a huge step forward with these , you won't go wrong. 

@kota1 My notes of several of the curves we have to deal with to get a coherent signal in our listening rooms is exactly on topic. @lonemountain said it perfectly "Active is not about where the amplifier is, it’s about where the crossover is." Absolutely!, Keeping timing issues coherent in audio is very difficult. It's more complicated that most everyone thinks even if you use DSP with all of your equipment on. 

If you are listening to a wonderfully recorded live album in which the lead singer uses a wireless microphone that recording will have internal latency issues if that wireless mic is digital like the best wireless systems are, the latency in digital wireless mics varies depending on the version of microphones usually a production company has many of these mics lead vocals, backgrounds, etc. so the newer versions of these mics are different and uses updated digital circuits. So all that to say there are very few modern recordings that are phase coherent from the start, When I was recording movies and TV and some music I had to use a digital mixer that was able to put a delay on each channel of different digital and analog microphones, that is very difficult and I didn't know of any other production sound mixer who did that, I really worry about such things.

Keeping timing issues coherent in audio is very difficult.

It will never be perfect but you can do what you can, often for very little $$, just some time and effort. I got a laser pointer/measurement device for like $20 and got my MLP the same distance from my front speakers as from my back surround speakers. Then my front height channels and angles the same as my rear height channels and angles. Then your DSP is able to do a much better job.

I found the angles recommended by dolby in speaker setup to work very well in my room too. All it required was moving my MLP to the center of the room and then I could place my surrounds and wide channels at the proper angles. Obviously YMMV depending on the size of your room. This diagram of Floyd Tooles personal HT is a good example of an equidistant listening position:

Floyd Toole’s Theater Floorplan

"Active is not about where the amplifier is, it’s about where the crossover is."

IMO the speaker setup in your room is free and the proper specs to follow are available for free. You just need to take a half a day to move stuff around. What knee caps a HT once you get the room right isn’t the source or the processor, it’s the power. Did you ever wonder why a company will sell a 2 channel amp for more money than a 5,7, or 11 channel amp?
How can a traditional power supply provide the equivalent SQ to MCH amps as a 2 channel amp? This is like putting a 4 cylinder engine in a Lamborghini IMO. Whether you use a receiver or separates your speakers are still knee capped. To light them up proper those speakers would need to be bi-amped with proper power. Good luck fitting 22 channels of amplification for a 7.1.4 system into your room.

Now, enter the elegant and dare I say BETTER solution. Unhobble those wobbly knee caps and add rocket thrusters like I did with active speakers in the HT. Free up space, free up budget, add a frigging lightning bolt of power and get out of the way :).

Post removed 

The SQ you get per dollar spent using the active HT is mind boggling.

You can go with 5 pairs of Yamaha HS8’s and a single one for a CC and a Yamaha CX-A5200 processor (or their next gen when it comes out) for less than $10K.

You could go with 5 pairs of Emotiva Airmotiv 4’s and a single for a CC and their RMC-1L Processor for less than $10K.

Of course you would want to add some subs (of the active variety) and you have simplified the entire HT process. Anyone reading this thread who wants a SOA home theater would be hard pressed to do better without paying 3-5 times the price. You get matching amps, speakers, and processors and all you need is a shelf for your gear, not a 6 foot tall rack. Take the $ you save on speaker cables and spend it on your sources and you are done!

If you got more than $10K get a JBL SDP-58 and 8 pairs of JBL 308P or their 7 Series monitors and stop agonizing about mixing speakers/amps, or whatever. 
 

 

Now, if you got more than $50K you got more matched/active options like:

Processor- JBL SDP-75

L-C-R speakers- JBL M2 (active)

surround bed channels- JBL 708P (active)

height channels- JBL 705P (active)

OR

You can get a matched active system by Focal:

Processor- Focal Astral 16 processor

Speakers- Focal Immersive Audio 7.1.4 monitoring system

Can anyone reading this thread tell me how to get a better system for the same $ with a passive setup???

When you have a LOT of speakers in a passive system you have a LOT of speaker cables. Not just in the runs but in the speaker crossovers as well. Those speaker cables can choke the signal. Why is it that some 8 foot pairs of speaker cables cost more than zip cord? To "unchoke" that signal. That can get crazy expensive if you run high quality cables to many speakers over distances, like in a surround setup. Active speakers eliminate that potential choke point while putting speaker cable budget in your pocket to spend elsewhere.

Has anyone noticed that a matched system of processors and active speakers also gets rid of the confusion surrounding your choices that the OP mentions? 

OP, you mentioned you have a budget for an upgrade. I have been holding off for a new thread but may as well get started. I don’t see a weak link in any of your components. Paradigm/Lyngdorf/Anthem/PS Audio is all top shelf.

Is there a problem in:

A) Component synergy/mismatches?

B) Room/system interaction?

C) You are a tough customer? After being around studios and studio budgets I would get that.

From your pics my guess is room/system interaction but IDK for sure.

 

 

@Kota1 Lots of great points one very striking one that goes right along with the OP is speaker cables. If they are a component and worth the price many people are willing to pay then eliminate them and go with active speakers. Many people who have decades of experience in listening to sound systems do think speaker cables do make a difference ok then why not listen to them and eliminate the cables we then that forces class D amps, Peter Lyngdorf has a speaker test with his D amps, you turn up the amp to 100% you put your ear next to the speaker driver if you can hear it buzz you don't have to pay for the system, 137db dynamic range is extraordinary in Steinway Lyngdorf systems. P Lyngdorf is a walking vault of patents for class D amps and his equipment may be an exception but it does mean that class D amps and 3.2kw power supplies are for real. 

 

OK, you got a Lyngdorf processor and PS Audio amps, the toobs are high maintenance and nickel and diming you on replacements.

Lyngdorf amps are of the two channel variety (SDA-2400) and at $2400 that works out to $1200 a channel. Your atmos rig has 11 channels so is it worth $1200 x 11 channels= $13,000+ to add 6 of those amps to your stack and hit the bid on the toobs?

If you miss your toobs get a tube based headphone amp. This one has a preamp out so you could use it as a 2 ch preamp as well.

You could hook the RCA out from the Manley to the RCA in of the SDA 2400 and the XLR out of your processor to the XLR in of the SDA 2400. You can switch between the inputs on the back and that amp would be driving your Paradigm 9H's.

 

@kota1 I've got the worlds most analytical headphone setup, the Focal Stella closed headphones and a Naim Unity HP headphone amp, both components are razor sharp and not very fun to listen to, accurate ya probably very much, I got that for working on video editing when you rally have to get the tiny details. Tube amps for the headphones would be great, I met Mr. Manley once he was very nice and very proud of his tubes and the way they sounded. 

I now I want to be active on my new system but I can't find a company that is totally system oriented other than Steinway and just 2 channels are $166K, and they don't even make surround speakers and I can't integrate the Steinway system into anything the connections are completely proprietary using cat 5 cable. I do want to put my money where I feel that the science and common sense leads but there are no alternatives. Sad.

I can't find a company that is totally system oriented other than Steinway 

Have you ever auditioned a system by Meridian?

I do want to put my money where I feel that the science and common sense leads 

Example of a common sense room, based on Meridian tech:

 

@donavabdear , the Lyngdorf Class-D is either off the shelf Purifi or customized. The brains is Bruno and Lara who started Purifi with Peter.  Those are Peter's words by the way.  Class D is almost a technical necessity for the bass due to high power in active, but for mid / tweet, not essential though a switching power supply becomes a packaging requirement. In professional products no one asks you what's the power supply. They only care about the sound. In the home market there are a lot of preconceived notions. There are also a lot more single ended electrical connections more susceptible to noise. 

 

That Meridien system was nice. Not a fan of the room and lack of treatment but they have to work with what the customer allows. They dropped the ceiling though, so could have created a 6" fake acoustic wall. All digital interconnect. Just standard Cat6.

I found the most amazing active speaker setup for you. It is SOA and probably the leading company in the entire category of active speakers. If you need help picking the right one start a new thread. If you want to do an atmos system wait until March when their new models are announced. 

Please click HERE and post any questions in a new thread. You will LOVE it!

Funny, @kota1 ,  they Sonos has tried to recruit me twice. How about you?

However, at least to the latest information I have, their emphasis, at least from a pure audio standpoint, is best audio in small size. There are a lot of parallels from a technology standpoint with achieving maximum performance in a large size, but parallels and goals are not the same. I did think their purchase of Mayht was wise though for their goals and it will be interesting to see if they push that technology up to larger sizes.

Let me know when you purchases your Meridien system, though at that point, like now, you will just be someone who purchased active speakers.

If you turned them down the joke is clearly on you. Well, at least you can still buy their stuff:

I am not up on all the latest in home audio equipment to even begin to spend $200K

I started another thread here that should be a good one to help you get up to speed, there some excellent system ideas. Feel free to drop by, I am sure you will find the help you need:

 

@kota1 , I would have quit while you were behind. My S&P Index fund has done way better, as has my O&G fund, thought I am not sure that has much legs left and even my semiconductor fund is screaming again. But seriously, I don't know what you think you are accomplishing with these little cheap shots you keep taking. I never called into the light your lack of any knowledge of active speakers other than owning them until you decided to start this childish game. It is obviously that one of us knows speakers and one does not. Hint, it is not you.

My market is speakers for professional applications. Why would I know the latest and greatest way to spend 200K in consumer audio? It is not my market. I could just spend 10 minutes on the web and throw out some links, but that is hardly expertise.  The correct answer to a question like that is a lot of questions, and perhaps some analysis of what the customer has. That is what I did. I did not start throwing out, repeatedly I may add, something that simulated a tube amp, when the customer did not even have a tube output amp. So again, I will ask, lay off the cheap shots.

It is clear that one of us OWNS speakers, and that one is not you.

You should quit trolling while you are ahead. All you have done in this thread is troll, complain, and whine. You FAILED the OP’s "test", in typical crash and burn style.

Clearly you have posted 0 pics in your virtual system, 0 info on your fantasy creds, 0 ideas about solid state amps that can replicate tubes, and 0 ideas on how to put together a system.

If I am counting correctly, that adds up to...0. 🤣
