I replaced my PS Audio BHK with a Benchmark LA4. Great move for me. The gain of the BHK is significant, resulting in noise with 6 and 7 volt tubes in my efficient system (might not be a problem with less efficient speakers and lower powered amps).
The Benchmark is spooky good - absolutely silent, imaging and low level detail improved significantly.
