Harry at VPI sold me a VAS Nova mono several years ago. It is excellent and when I had it refurbished by Steve Leung a couple of years ago, he also furnished a matching Nova stereo version. These sound particularly good for classical music to my ears. The service received was top notch and I would highly recommend this company. As a point of comparison, I recently had my Hyperion refurbished by Peter Lederman at SoundSmith. His work and his courtesy were also top notch, but it did take several months turn around. Not big deal for me because I have several cartridges, but it does seem that SoundSmith is quite backed up just at the moment. Two very fine companies, though, and we are blessed to have them both.
