Speaker Upgrade Question Quad 22L

in all honesty, these all appear to be sideways moves. what is it about the sound of this system that troubles you. on paper, it actually sounds like a very well thought out stereo. the quads may be a little light weight in the bass, but they are certainly as balanced(top to bottom) as the models you've named, and probably more flexable when it comes to matching components.

What do you find lacking with the Quads?

Believe it or not, boomy/bloated bass is my issue at moderate to loud volumes. I should have mentioned my listening room situation. I can only get the speakers 12" away from the back wall and 24" from the side walls. The room is 15' x 25'. (Speakers are on the 15' wall)I have been moving them around for a couple of months trying to rectify the problem but have not had much success. Since the speakers I mentioned have front firing ports, I was assuming that placement would be less of an issue and that would correct the bass problem. I know the Quads are quality speakers but in my case they do not seem to be working and that is why I mentioned them as the "weak link". I am guessing that most rear firing ported speakers would be problamatic in my situation. BTW about 200 hours on the Quads and components are all linked with Signal Cable premium XLR cables
