I have owned and sold a VAC Ren (not Sig) full function pre and now have a VAC Ren 30/30 MkII amp. The pre was excellent, has fantastic looks and build quality, it's extremely versatile and has the best remote I have ever come across. It sounded fantastic (l.s. and phono). I sold it when I went to a l.o. mc and I wanted to get into an active gain stage instead of the internal step up in the VAC. My Doshi Alaap is better, but not significantly better. I could have lived with the VAC, happily ever after. I did have to send it back once for repair and to have the internal loading resistor swapped out. The repair took a while, but it was sent in just before XMAS and then of course Kevin is out at CES right after. I would say that in terms of speed of service its about what you could expect from an artisan/boutique operation. The work was done well, it was not cheap and it took a bit of time.
The amp is fantastic; I bought it used here on the 'Gon and had a couple of concerns when it arrived. I emailed Kevin late one night and got back a detailed response first thing the next morning. Over the course of the next day or 2, we exchanged 3 or 4 emails; he was never anything but helpful, gracious and generous with his time. So I would say his products are expensive and provide a level of build quality and sound quality commensurate with the price. As far as comparing the Ren series of products to the moderate priced tube gear from China- well all I can say is we are not talking apples and oranges, we are talking apples and extra-terrestrials. Also, try getting some good diagnostic advice from PrimaLuna or Consonance on a piece you bought used. And then there are the QC and dealer/customer support issues.
