Have you looked at the Tron Syren (www.tron-electric.com)? This is a cost no object tube preamp with user adjustable phono stage. It is essentially a bespoke build to order preamp from one of hi-fi's unsung tube gurus, Graham Tricker in the UK. It has had rave reviews in 6 moons. I have the Tron's predecessor, the Tron Meteor, which is sounds stunning. This is used predominantly as a phono preamp with my platine Verdier/Schroeder Model 2/Allaerts MC1B. The US distributor is Highwater Sound in NJ.
If you email Graham (sales@gtaudio.com), he can build you one to your spec ie for your cartridge, with optional extras if you wish.
