Tube Amp for Devore O/96

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.

@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.

The Jadis was a KT150 but why would anyone use 88, 150 etc when 2a3 push pull out 300b work? Try some EL84 push pull or a 845 or 211

A nice Decware amp should drive those fairly well
