I too am a K&K phono stage owner and fan of Kevin's work.
However, I think you might be disappointed with most any active preamp after living with a TVC. I have tried many, including ARC, Audible Illusions, Art Audio, CJ, deHavilland, Lamm, etc. None of them could hold a candle to either my previous S&B based TVC (that Kevin himself constructed) or my current autoformer pre.
Unless you really see the need for gain in your system, I would stay where you are.
