I just bought am Adcom GTP-500 since it has a phono section. I had been using my NAD C370 as the amplifier and preamp. I had my subwoofer plugged into the preamp outputs of the NAD. Now I would like to use the Adcom as my preamp, but still use the subwoofer with line-level connections.
It occurred to me that I could buy 2 Y splitters and split the signal from the preamps out, send half to the NAD, half to the sub for each channel. Would this degrade the sound at all? Are there better options?
