When I owned Vandersteens a few years back and spent much time reading all about them, I'm pretty sure that at that time Richard used Quicksilver for his system at home. Whether he did or didn't you could easily do worse than trying something like the V4 to drive VS speakers.
Amp for Vandersteen Wood Quatros
I am planning to purchase a pair of Vandersteen Wood Quatros so that I can once again listen properly to large scale music in my best listening room. I am hoping to get advice/recommendations for amplification. System components - Analog via an Ayre-DPS turntable and Kenwood L-01T FM tuner, digital via a McIntosh MCD500 SACD player, Shindo Masseto preamp, Auditorium 23 ICs, Crystal Cable speaker cable, and Shunyata power conditioning. The room is 14' wide by 27.5' long with an 8' ceiling. The speakers will be positioned on the short wall, and the likely speaker front plane to listening position distance will be 10 to 11 feet. Many thanks in advance for your guidance.
