I recently received an email from the Perfect Vision reviewing the B&K Ref 50 and matching amp. After reading the review I am somewhat confused and confounded. The reviewer gave high marks to the pre as far as features and user interface. It also was highly rated for dvd video performance. Surprisingly, based on a previous review in the magazine of the Ref 30, the reviewer thought SACD on the Ref 50 sounded great! But then, in evaluating the performance with two channel CD, the reviewer claimed the pre/pro sounded chalky and dry. Leaving aside for the moment what such terms mean, I am stumped how the reviewer could reach this conclusion. Both SACD and CD audio through a CD player go through the analog circuitry of the Ref 50. While it is quite possible that a SACD sounds better than CD due to superior technology or recording skill, I see no way to account for these differences in sound other than recording quality. Anyone have an opinion on this?
