@fjn04 04-18-2018 8:12amI had the balanced and unbalanced V4’s. I really enjoyed these amps, though I have never heard the KT 150. I tried an EAR 912, and I can tell you from a sound and synergy perspective, it was a good match. I believe I had the balanced version of the V4’s at the time. If I had these amps again, the preamp I would want to try would be Shindo.
Which Shindo preamplifier?
Currently running a 6SN7 based tube preamp with my QS mono amps (KT150s) and really like it, thus maximizing the capability of the amps. Interested in what others have tried. Seeing several preamps listed on the Shindo site.
