I recently decided to upgrade my speakers to Paradigm Reference 40's. Now i am getting the bug to replace my receiver, I bought a few months ago , a low end sony w/DD and DTS I like the 3801 and have a question i cannot tell from pics. 1) How many pre amp outs are there? I would want enough for RL,Fl,c,sr,sl,sbl and sbr and sub. I would like to get a amp in the next year or soand use this as a pre amp.
