Here for sale is Graham Tricker’s personal Tron Seven Dual Mono Phono Stage in GT spec which means you have a completely separate phono stage amplifier for each channel. The improvement in soundstage width and depth as well as image placement has to be heard to be believed. It has been built to the highest standard and is fully silver wired and is probably the best phono stage money can buy. Currently it is in MM configuration and is best used with an SUT (Step-Up Transformer), but it can easily be converted to MC if requested. As a state of the art phono stage it really doesn’t get much better than this. This unit has been very rarely used. I would estimate its had about 100 hours of use and is in like new condition.
