Hi Charles and Daveyf.:
The amp. is special for sure and so is the Gamut preamp as a mate. I also heard the preamp.with the Korneff 45 and Border Patrol 300B. The D3i sounds very relaxed and as natural as tubes. I have owned the EAR 858, VAC Signature SE, and CJ GAT and this one is just more musically inclined. Gamut is not well known in the states but I encourage you to check them out.
