The mono amps have not shipped yet. I am still waiting for mine as a beta tester. I was hoping we would hear word that they would be built and sent out this week.
I have the Musical Fidelity Nuvista 300 mono amps that I will use to compare to the BHK monos. I realize this is not a current amp, although, in its day it was very well received. There were only 500 numbered units ever made and they are rarely seen in the used market. As well, they are a hybrid design, which may make my comparison quite interesting.
Paul did mention yesterday in his May PS Audio newsletter that the BHK Mono’s will be at the Newport Show in their first public showing.
