Tube Amp for Devore O/96

I have heard O96 in the same room with:

100w Jadis integrated, 50w Riviera Hybrids, 20w Silvercore 833c, a German 300b 20w, and New Audio Frontier 2a3. They were best with the NAF. 

In another room, with Airtight EL34 34 watts, and Airtight 300b integrated 10w. They were best with the 300b. 

I have also heard them sound good with Mastersound 845, and not sound good with Kondo overture (el34) and unison research. 

My take is that, especially if you are analog and like the recordings to show through, simple circuits and set ups are better with the O96, with some drive, hence the push pull 2a3/300b types work best

Has anyone here heard the O/96 with good KT88 pentode mono amps?

I haven't heard either amp.   Both are probably more amp that you need for your efficient speakers.  the Jadis is Class A which the CJ is ultralinear which is a compromise you don't need.  So between these I'd definitely opt for Jadis if I were buying from specs alone.  You could do fine with a pure SET such as a 300B.

+1 New Audio Frontiers 2A3.

Heads up I'm a NAF dealer.

@flipturn That speaker is easy to drive so you have a wide range of amps to choose from. Its not efficient enough (unless you have a small room) for SETs (which should not be run past about 20% of full power in order to avoid excess distortion) unless you have a really powerful one. The problem with those is they audibly lack bandwidth.

If you are set on tubes look for a triode amp that is push-pull. That will get you the power you need; triodes have linearity that pentodes and tetrodes don't. They allow the designer to build a smoother and more detailed sounding amp due to lower distortion.
