Hi ... so here's an update: I now have both of the ways that you suggested to me
I have decided to upgrade my computer's audio with the active speakers ... so there's now the old amp in the other room with the traditional HiFi system and the active speakers on the PC.
It's a pair of Behringer Truth B2031A and an M-Audio BX10s woofer.
Not cheap, but first I bought them used and second I decided to invest a chunk of the money I had reserved for the compilation project - which is currently not happening anyways.
The active system is brilliant. I never heard a sound this clear on any audio system I owned previously. Only "problem" I have with it is: I am now at 12% volume and the walls shake. You can bet the neighbors gonna come over in no time if I continue like that
