I am looking into buying new front speakers for my system. I just heard the Bose 601's and was blown away by the width and envelopment of the sound. I'm just wondering if anyone out there has these? They're not cheap at just under $1000.00 CDN. I am also looking at the Bose VCS-10 centre speaker - they say your front speakers should all be the same make. However the reviews of this speaker are rather ugly. Would appreciate comments. Also the selling point of the 601's is improved bass quality. I already have a sub-woofer - would this cause an overabundance of bass?
