I just ordered the Schiit Freya+ preamp and need some ideas for a new amplifier to match up with it. Not sure if class A/B, class D, or class A is the answer. I just know that I want the power, drive and grip of a SS state amp to go with my new tube preamp. The Freya has balanced inputs, so it might be time for me to go that route as well. Anybody have some recommendations? I am trying to keep my amp budget under 2k.
