Thank you, while I wait for reply regarding gain decrease, I'd like to ask for some opinion.
The story strats after I am no happy how my new Yggdrasil DAC sounds with Brystone connected with balance XLR.
When it's unbalance RCA connection all is fine, but trough balanced interface, it somehow distorted. I hear strong mids while bass lack extention. And what is worst it's not scale with volume... with more gain, bass remains low and mids just go very loud and not pleasant. Some sort of non linearity is there. Like low spectrum truncated somehow.
While digging, i found out "interesting" balanced output realization in Yggdrasil. For some reason Earth (Pin 1) shorted with Negative signal (Pin 3). I heard sometimes it's used in consumable (not pro) level to avoid some issue. So my guess, maybe Bryston as fully balanced just don't like this type of interface. Maybe somebody could help me. I though maybe disconnect Pin 1 inside one of the cable connector to avoid it spoil Brystne circuity? Any advice?
