I owned Quicksilver V-4 mono blocks for 10 years in my system which was based around Vandersteen speakers, 5's and Quatro's. I switched to the Aesthetix Atlas from the V-4's and was very happy. If you can hear the Aesthetix I think you may find what you are looking for. The Aesthetix is a hybrid amp and uses 6SN7's for the input stage. The Quickies are great amps but once you hear the Atlas on the Vandersteen's it's hard not to make a change. This is just my opinion and YMMV.
