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


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

https://www.audiogon.com/listings/lis9jhj0-david-berning-co-211-845-otl-tube

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?

There are a pair of very handsome Audio Research ref amps on that vendors site for 1/3 the cost and they look very nice as well.

I consider getting Zotl Z10e reference 10-watt electrostatic headphone amp for my Stax 009s headphone next year.

You're best off choosing the most transparent amp you can afford -- otherwise you're not benefiting from that plasma tweeter.
In my listening room, 48 Watts SET is enough to drive my Lansche speaker ( oficial eff 99db/w, but I guess 95db/w)
Interesting. The Lansche I heard (a 3-way with 3 front firing drivers) began to sing only after we connected +60W class A (SS) to it. If you're getting away with a 45W tube, I'd say stick with it! 

Otherwise, you need to search for amps that give you both power and transparency, i.e a major investment in money & time; at this level, we can offer only "possibilities" IMO.

To return to your original choices, I haven't heard the big Berning; the big Jadis, however, are not it (outstanding though they may be). Regards
