I drive my 60v5 with VTL and Classe electronics and have absolutely no issues with their highs. They are very punchy and detailed but need a quality front end. I tried them with some NAD integrated and, as expected, they sounded rough and chalky. I think the version 5 Studio 60s outperform and are more revealing than all previous Studio 60s as well as most speakers in its class. I bought mine to replace a pair of Vandersteen 2CE Signatures and have not looked back.

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!
