I'm back......
After following Lordoftherings 6 step program, I did notice a difference, but the problem is still very much there. After reading through the other posts in this thread, it is apparent that I am battling a hardware issue more than anything - specifically front speakers.
Just so y'all know, I ended up with the Polk Monitor 50's when I found them on Slickdeals.net for $70 a piece - shipped!! hahaha Seriously, before the 50's I had the Monitor 10's and were satisfied with them. (of course I didn't have unrealistic expectations from a bookshelf speaker) I do like the Polks because they seem to offer more treble than other speakers in their price range. (cheap) When I saw the 50's for such a "good deal", I ordered a pair thinking that they would be as good as the 10's in the treble department, and would bring an appreciable amount of bass to the table. Boy, I was dead wrong. Oh well, chalk it up to experience I guess.
The Denon I ended up with when a customer of mine upgraded to one of the new "uber' Denons and sold me the old one for -- ya'll are going to hate me for this -- $100.
I bought the HSU sub after doing some research here at Audioholics. I love that thing - other than the fact that it leaves all my other crappy speakers in the dust! hahaha
I like what TLS Guy said about front speakers, "When the OP goes and buys speakers next time, he should find speakers that sound great without a sub. All speakers should be very listenable without a sub. If a speaker screams connect a sub, pass it by. The sub should just guild the lily." That makes perfect sense. What I need you guys to do is recommend me a set of "older" front speakers that will do the job for me. I am very much on a budget and cannot afford the latest 'n greatest. Surely there is something used in the $300 +/- range (pair) that will work. They don't necessarily have to be tower speakers either. If y'all know of a set of small speakers that will work well together (and with the Denon and the HSU) I'd be up for that too. I am open to all suggestions. Thanks again for everyone's help!
