ive just upgraded my Bryston .5b to a YBA2.I understand that this preamp inverts absolute phase.How can i tell if the phase is correct or correct it if its not.i also was wondering if most higher level preamps do this....any advise would help greatly. thanks in advance.

About half of the CDs out there have the absolute phase reversed anyway. This makes a HUGE difference in the sound quality. The absolute phase MUST BE correct, so you (and everyone else) needs a component with a phase reversal switch. Some of the major labels with reversed phase are: Mercury, Capital, RCA, MCA, DG, London, EMI, Sony, Telarc, Teldec, Epic, Vanguard and Warner Brothers. For the complete list, refer to the article in FI magazine, September 1997. Food for thought: Years ago, many pieces of tube gear were raved about by high end magazines who loved to use RCA shaded dogs and Mercs as their test records. A lot of tube gear reverses phase so with these records, the absolute phase was correct. How many incorrect decisions were made because of this?
