The tube rectifier uses a standard 5U4G, it can easily upgrade with our STR-104, STR-1001, STR-1002 or STR-1003

This superlative unit can easily surpass the sonic performance of any competitor’s pre-amp which is not built with transformer coupling and organic tube rectification.

This pre-amp uses the purest ORGANIC design, no negative feedback, no circuit board(PCB), no transistors, all component-to-component hand wiring, built with very high grade selected components. It also features fully balanced input and output capabilities.
