Tube Amp for Devore O/96


Hi everyone,

I'm wondering if anyone here has any experience with the Jadis  DA50S amplifier or the Conrad Johnson 62SE or 120SE, or have thoughts on these two amplifier manufacturers generally. I'm wondering particularly how these amps compare and if any of them would be an especially good match for Devore Fidelity O/96 speakers as I move from solid state to tube.

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
