The problem here is that when an opinion is backed up by subjective experience (my friend's findings re SME vs BB and my findings re the S7 vs vpi HRX and SME) you claim that the Brinkmann was not optimised and if it had been it would have been preferred. This is little more than wishful supposition.

Have you ever considered whether the SME 30/2 was optimised when you auditioned it? Where was that btw?

Your technical arguement may well stand up in theory. But only in THEORY. When respected audiophiles claim that the Brinkmann is totally outclassed by the SME30/2, the subjective listening results do not support your claims.
