We've drawn a blank at rearranging our room in any other way other than at present, where our B&W 685 speakers are placed either side of a chimney breast and rather too close to both the rear and side walls. I've been experimenting with the port bungs, and minor position adjustments of the soundstyle stands. Although the system sounds good, I feel there are uneven frequencies, some booming of the bass, and inconsistent soundstage, although some of the time I don't really notice it. Given the poor speaker placement, is this the best I can hope for, or would there be any point in trying different speakers? If I tried different speakers, my budget would be roughly £500 - £800. My amp is the Rotel RA1520, with Audiolab CD8200.
