Forgive me if this has already been discussed, Ron, but to state the obvious: why not try an Apex with your speakers?

Apex, meaning in this case?
 
Another thing to consider is that rooms also can run out of headroom. What might seem like compression may, in some cases, actually be room distortion at the high volume played at. I have experienced this myself, only knowing about it in hindsight after I further fixed the room.
Spot on Al, there would be very few rooms that could take 100db without a massive increase in reverb in which case you have no idea how the components are performing. In all these discussions about amps, efficiencies and topologies the elephant in the room is ... errr ...the room.
The treatments Ron has done, while fairly nominal, clearly work to a reasonable degree at moderate listening levels but it is not a scientifically designed acoustic. To achieve bonzo's ideal quest he would have to take the room with him
Cheers

Interesting, Al. I don't know, with the adjacent equipment room acting as kind of a SPL vent which almost doubles the interior cubic footage I'm skeptical it was the room.

Phil was playing so loudly I was nervous he was going to blow the drivers.
Candidly, you’ve done the same in my room!

I can play symphonic music cleanly (without reverberant field smearing) at 100 dBC peaks. But with orchestral music, I tend to set volume so that low energy sections are clear … and I let the high energy sections fall where they may. The room is about 500 square feet with 10 foot ceiling, and I’ve incorporated diffusion, diffraction, and absorption features. I am actively wondering how much clearer things would be with Alexx Vs, or some other larger speakers, but I am very happy with the clarity of the Sasha DAWs.

I do not use room correction in my two channel system. The HT room clearly benefits from it. But I can’t bring myself to try it in the legitimate audiophile space. When people post recordings of their systems, I often get the feeling that they’ve got done equalization that is enhancing the midrange… but it is just speculation.

Toss into the mix you can get a BACCH with room correction software now. And some are selling their MSB Select to just use the BACCHs internal DAC.
My fear of room correction while using digital sources is the learning curve to set it up. My personal belief is your going to get better playback using it than not.

I have also heard those that have the best success with room correction software have also spent the time and resources on physical room treatments as a foundation. They get as far as they can mechanically. Then they fine tune with DSP. If you drop a BACCH on top of that, I bet your in a next level place.

AJ that's a pretty decent room size I assume you have quite a bit more treatment than Ron to achieve a clean 100db ?
Most room correction you see is to a single point and many view the off axis response as equally if it more important ... I know the lyngdorf system does an averaging correction ... that would be the only issue in my view plus of course the quality of components etc.
If your room works well in mid and upper range then bass is bound to be improved I would think.
I sort of use room correction of bass with a minidsp crossover which is to be converted to an analogue active xover now I have my desired transfer function sorted by in room measurements

Not obvious at all, so nothing to forgive.

1) Pendragons do not need that much power.

2) Not once in my life have I ever cared for the sound of any solid-state amplifier on any electrostatic panel or on any planar-magnetic panel or on any vertical ribbon driver.
 
Hello Brad,

What is your opinion on the KR Audio VA200?
 
Hello Brad,

Never got to hear that one. It is not SET but is a circlotron, which is usually used in OTLs like Atmasphere or Joule Electra. The KR has output transformers though. It uses a lot of 842VHD output tubes, so will get very hot.

The other brand that uses circlotron with output transformers is BAT. The BAT REX-3 monos would perhaps also be an option to consider as they are like 160 watts of Class A triode power.

A stereo version makes 80 watts, which might already be enough, but could be converted to mono and another purchased later to give more headroom if desired.

I heard a pair of the old VK-120 monos back in the day with VK-5i preamp and that sounded very good.

Lest we forget a more recent implementation with the Aries Cerat lanus line of pure class A Circlotron / TriodeFet amplification Viz the Geminae .

Agree - one should follow his/her heart ??!
 
Either way, with more and more videos being uploaded, the future's in the air, I can feel it everywhere, blowing with the wind of change. Videos are where audiophiles share their dreams (share their dreams)
