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


There are two interesting 80K$ tube amps on sale at Audiogon.

The first one is David Berning OTL design with output of 60 Watts.

it looks beautiful. But I had never used OTL amp yet.

I am curious how it sounds with high efficiency speaker.

The second one is Jadis JA800 with 6 pieces and 400watts.

I had used JA500  (only 4 pieces with 350 Watts) from 2000 to 2002 to drive B&W Notilus 801 with utmost authority and unbelievable slam.

It was kind of lifetime experience to own this beautiful and overbearing monster.

But I could not use it during summer time in modest size room.

Thus I let it go and got Silbatone 300B SET amp to drive efficient full range speaker.

350 Watt to 8 Watt

If you have money or hit the Jackpot, which one will you go for?

Do you really think anyone reading Audiogon forums are buying 80k amps? No they're reading the Robb report!
What was a really enjoyable, interesting and insightful thread has taken a different turn with the latest posts. I hope that this thread restores/retains the original good vibes and camaraderie. I just believe what people decide to spend is their own business.

What makes the David Berning amp so special?
The output section topology gets around the traditional limitations of conventional transformers and so allows much wider bandwidth from the output section, regardless of power output. If you are wanting single-ended, this is arguably the best way to go. If you want a bit more power its especially useful, as the traditional issues that limit SET power and bandwidth simply don't exist.

It might be more accurate to call it 'Radio Frequency coupling'. The technique has produced IMO some of the best tube amplifiers made.
