I found a local dealer who was kind enough to let me take a Studio 60 V5 demo pair home. I had to pay for them first with the option to return. The were beautiful speakers and I really wanted to keep them (especially at half-price for a demo pair that was like new). I listened to them side-by-side with my Monitor Audio RS6, and in my system and room the Paradigm seemed more revealing and detailed than the Monitor Audio, but unfortunately it came at the expense of being more harsh and bright. I ended up taking them back because it seemed more like a lateral move than an improvement. Again this is all just my opinion, but it seems to be the same issue you are finding.

The highs have an edge that hurts my ears, especially female voices (e.g. old joni mitchell, Emmy Lou Harris, etc. I have a Denon AVR 1709 80 W/Ch home theater amp. Could the amp be the problem? It's not room placement - I've moved them all over the room, and it's not interference - it happens even when I only have one speaker plugged in. If it is the amp, what should I replace it with? I spent all my $ on the speakers, assuming the amp I have would work out. I have the speakers for sale on Audoigon but would like to keep them if I can find an affordable solution. Thanks!
