Should PS Audio ever choose to tinker with the BHK, I think it would be nice to have a mechanical bypass instead of an electronic one. Although I no longer mix my audio and video systems, one feature I found really useful on my old pre when I did was the ability to completely bypass the preamp when I was watching movies.
What brought this back to me was that there are times when I want high quality background music, but I don’t want to burn tubes. I thought: wouldn’t it be nice to be able to bypass the BHK pre (without swapping cables) and listen to the DS straight to my amps, and save my tubes for serious listening?
Just a thought.
