I was wondering who did the design. Puts a smile on my face. Westlake's digital designs have probably won more accolades and achieved more sales than any other hifi engineer. I had an MDAC+, great bit of kit that cost me £650 new. It improved upon a many times more expensive PS Audio DAC.I’m 95% certain that Stack commissioned John Westlake to engineer this piece. I can spot his layout technique from space.
[I’m guessing that part of why Stack keeps quiet about it is that Westlake, while a sharp engineer, has a good bit of controversy following him over long-delayed and then abandoned altogether projects for which he collected a lot of money from users in advance. You can Google that.]
