TVC preamps: good or bad?


I was wondering what the advantages and disadvantages are of a TVC preamp? I have read elsewhere that transformers introduce coloration and aberrations in the frequency response, which is why we try to get them out of the output stage of valve amps. But ... what are the pros and cons of TVC preamps?

The ASL Flora uses autoformers. Audiogon member Teajay wrote a review of his that you can look up here. It replaced a Bent Audio S&B TVC in his system (which he also wrote a review for).

Bent Audio is now using a custom version of the Slagle autoformers instead of the S&Bs. According to John Chapman the first few units are now in production and as soon as he stocks up on parts he'll be ready to go to full production.

Ktstrain, nice work on your AVC. I'm looking to have a custom one built for me that will include a phono stage (most likely the K&K Audio kit). Hopefully I'll have the details all worked out soon. If you have any advice for me on design feel free to email me.
