I have an HSU VTF-2 MK5 subwoofer (which I learned about from this forum, thank you very much!) in my 5.1.2 HT with a Yamaha RX-A1060 and upgraded Klipsch Forte II's as mains. I listen to more 2 channel in this room. I have another primo HT system in another room, but still use the room for movies, etc. I was wondering if I found a tube amp with a sub out for 2 channel music, would it be safe (for all equipment connected) if I "Y'd" off the HSU subwoofer to both amps as long as I was sure only one would be on at a time? My thought was to use the Forte II's for music with the sub. And then for the HT, get a different set of mains, probably bookshelf size. I am sure I could find a good placement for them. Comments?
