Anyway, going directly into my Mcintosh MC205 obviously bypasses the subs and the result was predictable: very clear and transparent but bass thin. Plus I missed impact I get from the lack of subs, which I have time and phase aligned.You do what I do, put a Y connector on the back of the PS Dac and drive the subs as well. Then you can have it all.
