Like many of the men who responded earlier, I am a big PS fan and have been for many many years. My current system includes much of their gear including a pair of the BHK 300 mono blocks. Those are phenomenal amps and were a big improvement over the single BHK 250. That being said, i doubt i will spring for the new amps as they are just out of my reach financially. I do know from experience with PS Audio, that these new amps will be killers and will probably compete with more expensive amps from companies like D'Agostino and Constellation. BHK was a brilliant designer and he will be missed.
PS Audio BHK 600
Word on the street is that PS Audio has pre-full release offered their new BHK 600 mono blocks to existing customers. Looks like a P20 power conditioner without the display, so $0 spent on the external design and aesthetics (still ugly, unless you prefer the microwave look for your audio equipment). None the less, MSRP is $32,500.
