The TRON Seven will be available in the UK as well as the USA; the Phonote, which is a cheaper version will be UK only. I have Graham Tricker's personal demo Tron Meteor preamp (predecessor of the Syren, but with v similar circuits etc), as I have been one of Graham's customers in the UK for the last 15 years. The Seven is based on the phono stage of the current Syren preamp, which retails at upwards of 6k GBP depending on spec. It is designed to be a no holds barred unit for MC only. If you want a bespoke unit, Graham will make it for you. Graham said that he could decouple the MC transformers from my phono circuit (v. similar to Syren and Seven), but this is a factory mod, not just the removal of a couple of jumpers.
I'm very pleased that many of you from the US are finding his products thought provoking. Some of us in the UK have been great fans for years. His Syren preamp is stunning. I gather from Graham that his current US distributor, Jeff at Highwater, is providing excellent service.
By the way, my TRON Meteor pre is fed by an Allaerts MC1B/Schroeder Model 2/Platine Verdier front end and drives rebuilt Quad IIs (rebuilt by Graham 15 years ago and serviced by him) an Avantgarde Duos.
