Solid state amp that tube fan can be happy with?

Look at Class A Accuphase amps

Conrad Johnson MF 2550 is not made anymore, but I think it is a good candidate.

@pryso There are class D amps now that are smooth and detailed through the mids and highs like an excellent tube amplifier- so much that its hard to go back to tubes.

Luxman is a great option here.  Ayre too, but needs auditioning.

It will never sound exactly like tubes. SS can in fact sound sweet, and really really good, but will never be quite as full and warm as good tubes (and EL34 are pretty sweet). And when SS goes TOO warm (maybe in an ill-fated attempt to match tubes) it just goes flat and becomes a mess. 

But, "a bit sweet" might be enough, depending on your ears and the rest of the system.
