Class A amplifier choice, need suggestions

The McCormack DNA-2 Revision A may still be a class A/B after the upgrade, but it's very powerful and musical. Mine does run a bit hotter since the Revision and the bias may have been tweaked. My speakers are 88db efficient also and you'd be impressed by the effortless control provided by this amp.
It's 300w/600w/1200w from 8 to 2 ohms. Check the classifieds.

I haave not heard anything better in solid state class A then Symphonic Line Kraft Reference 400 and 250, either stereo or mono.

Gvatchna, you beat me to it. IMO, the Kraft ref 250 class A stereo should be sufficient for the 3.8's. I heard mine driving a slightly bigger Proac and was very impressed by those speakers.

But, Detlof's Jadis -- ahhhh.

wait-a-minute,
class A in terms of rating or class of operation?
basing on the above answers I believe that class A in terms of rating is being searched.
plinius(basically any model) is a great choice when driving low-impedance speakers. SA250 has a long margin of class a(upto 35W?) and than switches to B for more current. McCormacks are all bright and extra-coloured. Pass Aleph 5 is great but has a bunch of limits of performance if played something more than chamber or small-band music.
another great choice is GamuT D200.

Solid State Amplifier: Pass Labs X350 or higher
Vaccum Tube Amplifier: Audio Research VT200 or higher
