Need some advice from soemone more knowledgable than myself here. I have a pair of tube monoblocks powering m80's, along with a tube preamp with two outputs. Recently came across an HSU STF-2 subwoofer that I'd like to add to my 2 channel system. I'd prefer not to use the <input from amp/output to speakers> connections on the back of the subbecause I think I might lose soemthing from my monoblocks, but the subwoofer only has a single rca "sub-in" jack. What's the best way to use my second set of outputs on my preamp to use this single sub-in? Can I just use either the L or R output from the preamp to the sub in, or may be a Y connector to join both L & R into the single rca sub in? Or should I just be using the speaker connections? Any advice would be appreciated. Thanks alot
