Nagra VPS or Tron Seven Ref phono stages?

I haven't heard the Nagra, but I have heard the TRON. Anyway forget what I've heard. Thomas Woschnick (the TW Acustic turntable designer) uses a TRON Seven Reference in his own system. Apparently he wouldn't let GT take the TRON back to the UK after GT brought it to his home to listen to last year. Now I would trust TW's judgement.

The TRON is made to order, like a Savile Row suit. Speak to GT (via Jeffrey or with Jeffrey's help) and you will get a TRON perfectly matched to your cart's gain and impedance. It might take a few weeks to arrive, but bespoke tailoring takes that long too.
