You will be very happy with the Treo CT's. I know this has been said many times about Vandersteen, but proper set-up is extremely important. Most notably the back tilt of them. Your choice of equipment looks pretty good. As Bob said you could experiment with Audioquest cables, but after listening to Jim's (tomic601) system with Kimber, you will do just fine with what you have. About the only suggestion I would make is maybe try a CD player that has just a tad warmer sound than the Oppo you have, all though I see nothing seriously wrong with it's sound. I use a Ayre Codex Dac, which makes the overall sound a little less "digital sounding" if that makes any sense to you. Good luck, and enjoy the Vandy journey, you're in for some great sound and fun!
