Kieth Munson feedback

The SBS amps are incredibly punchy, and feel very smooth across all registers.  They feel very precise without being sterile. 

Tracks that I’m very familiar with sounded cleaner and much clearer than I’m used to hearing.  Subtleties that were lost listening on the Krell amps through the same system re-appeared with the depth and clarity that were intended on the SBS Amps.

I was really impressed with the way the S2 sounded in the control room hooked up to some Pro-Acs compared to the Bryston 4b.
