I use a Stereomour and a Sex 2.1 fed by a Shiit Bifrost MB. Im getting tired of changing the RCA cables from one amp to the other. The DAC only has one OUT. I don't have preamp, so Thought I would make up two Y cables so I can run a second set of RCA cables. Bad idea? Any signal loss? Should a build a switching box instead ? Be happy for some feed back...Max
