I'm a big Steve McCormack fan too. I own his DNA-500, DNA-1 Deluxe (center) and soon his modded DNA-225 (rears). I met the man in person at RMAF and listened briefly to the system that included his new pre. There is no way on earth to separate what I heard to focus on the pre, though. The system (Audience/SMc) sounded nice but no idea what sonic aspects were related to what piece. Visually the VRE-1 is a beautiful preamp with nice lines and a very compact and well-built feel.
BTW, at Steve's recommendation I replaced the stock DNA-500 main external AC fuse with HiFi Tuning one and the sound has become more open and ever so slightly warmer (good, in my case) after an initial break in where it sounded a bit more analytical at first. I plan on taking the next step and replacing the 12 internal fuses (yes, 12) sometime soon.
