Which one to choose between two 80K$ tube amps?

atma-sphere,
I understand that 3rd order harmonic distortion amplifiers generally have less overall distortion. But, is 3rd order harmonic distortion as easily/naturally tolerated by the human ear as is 2nd order harmonic distortion which is quite well tolerated. Some would say that in fact 2nd order Harmonic distortion is congruent with human hearing.

and those very high impedance speakers just don’t cut it when the music gets really complicated. the superb aspects of those speakers becomes just ok to good when things really start cranking and wild.

Avantgarde Trios with basshorns can't do this? or the big Cessaros? Not sure I agree with you here.

I think your speakers are simply harder to drive in a large room than one thinks.

depends on one’s expectations for large scale, complicated, reproduced music.

i’m not saying you are limited in musical choices with those very high efficiency speakers, only that those very large scale recordings are not the strength of those type speakers. whereas it is the strength of large dynamic cone speakers. it’s still not easy to accomplish.

the only performance limitation in my room is the limits of SPL’s on the capacity of the human senses. the system exceeds those by a good margin without losing it’s grip.

Two amplifiers that represent the pinnacle of decades of design development of two legends in the Audio world, Kondo san and Berning san. I speak from a listener and enthusiast’s perspective. Not from a technical one. I do not discount the importance of specs and technical aspects. But present the importance of enjoying the music. If someone’s tastes lean toward the “cool and neutral” presentation, the Berning is perhaps the ultimate example. If one’s tastes are more the “warm and liquid”, the Kondo may be the best there is. Both amps are highly “musical”. Perhaps the classic yin and yang. Personally, if I had the cash and inclination, I would jump at a chance to own the Kondo for $30+K less and never look back. Especially considering the “taming” of that plasma tweeter!

Clearly, both are SET tube based. However, when I refer to “warm and cool” I speak of the designer’s tastes IME.
