Tube Amp for Devore O/96

I unfortunately haven't heard those amps but do love the Devore Fidelity 0/96! A few others to consider:

Atma-Sphere S-30
Audio Mirror Reflection Monoblocks
Margules I-240 Integrated

I have heard all three and owned both the Atma-Sphere and Margules and all would be lovely with the Devores. I am a Margules dealer as well and would say the I-240 is a magical creature despite it being only 25wpc. I prefer it over any other EL34 amp I've had. Lots of good press on it recently.

Thanks so much for the recs! I'll definitely include these in my amp research.

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.
