This is just my opinion, but you can loose a lot more than you can gain if you switch without auditioning with your speakers. I think mini utopias are too 'lean' sounding, for my taste, to match them with equaly lean amps. I do not think that ss amp exists, yet, that sounds like a tube amp. But unfortunately there is a plenty of companies that succesfuly made their amps sound like SS (ARC, SF...etc) There is no such a thing as a sure thing, but i would look into Jadis Orchestra integrated amp or any other harmonicaly rich sounding amp. Again, just my opinion!
Any SS class A experience to share?
I'm looking to upgrade from my beloved VAC Avatar SE only because I'd like tighter bass. Depth is fine, but I also want "slam". I'm thinking: Tube preamp with a Class A Solid State amp. The VAC is only 30 watts in triode mode and that is more than enough for my efficient JMLab mini utopias, so I'd rather not spend the money on power I don't need. Can anyone out there share their experience with these types of amps, especially when mated to tube preamps such as C-J, VAC, Hovland, Blue Circle, VTL, Asthetix, ...
