Amps which are Great, but either Unknown or Underpriced

Hello everyone,

When I think of Power Amps (or integrated amps) that play / sound way beyond their price-point and can be non-household names, I think of companies like:

1. Belles (Power Modules)
2. McCormack
3. Coda

Can you guys please suggest other Power Amps / Companies that are also somewhat unknown or of great value?

Your suggestions would really help me and others.  Thanks!

Matt
