If only MF would release a replacement for the B1, in spec, performance [comment in a review in Gramaphone mag when B1 introduced ".... unneccessarily good"] and price. Something to go for instead of the ubiquitous Marantz X000X
I had my B1 [and another on standby if the original ever went down. It never did] for 30+ years. I only gave up on it because I needed digital inputs.
