I agree with Fjn04 you should listen with your amp before making any changes. How and what you listen to will determine the best amp for you.
I too heard the Crescendos @SOS. Steve was using Atma-Sphere MA-60 with an Audioformer and I felt with some materials, it could use a bit more control.
For a perspective, my system is very different with SS amps. Main reason for my visit is to checkout Atma-Sphere amps. Haven't heard them for a long long time and investigating a tube amp for my system.
