I have two M500t amps, and had both restored by someone I found on eBay. I had major/minor problems with both, so I sent them to Greg to look at. Greg opened them and sent me photos of what he found, and it's clear that someone who does not know electronics can be taken advantage of, as I was to some degree. So, bite the bullet and get your amp done right, by Greg, the first time. You'll save yourself a lot of time and money. Looking at the attached "before and after" photo, even to my inexperienced eye I can clearly see the difference between the "'eBay build" and Greg's workmanship.

I have always wanted one of these little technical marvels, and the opportunity arose when I bought one to power my C-4000's time delay speakers. Greg did a marvelous job getting my M-400 working flawlessly, and his communication with me about the process was just as good as his engineering skills. Thanks Greg.

Years ago, when they first were sold, I had a C-4000 but had to sell it. Recently, I wanted to return to the pre-amp but I was hesitant because of its complexity and age. Luckily, I found Nelion through the Carversite, and reading the recommendation from Bob Carver about Greg's work was all I needed to see. I bought the nicest one I could find and shipped it to Greg. I received it last week, and it sounds fantastic. I can't take my eyes off it, and can't stop listening to it. Although it is a complex piece, if you truly admire Bob Carver's work it's a privilege to have one of these as th
