Tea and I read a review of the Bricasti Class AB monoblocks used at that show which led us to believe they might suck. Tone and timbre were fine, but the overly smooth sound lacked bite. Probably the amps' fault. Off topic, but DSD offered an improvement in stage depth with M12SE vs PCM. Anyways, try to PM Tea about Convert-2 vs M1... He's very familiar with both.
