The P20 is the top phono stage in the Pure Sound range. It is an all valve design, as you'd quite rightly expect from this excellent manufacturer.
The heart of it is a power supply that uses two transformers to feed the wonderfully, and rightfully, simple audio circuit. Just two dual triode valves are required, and unusually at this price point they interface to the outside world through a pair of output transformers.
The use of output transformers is normally limited to the most expensive products, as they're costly to do well, but they do bring big benefits. They enable a simple, purist signal path, and bring with them a low output impedance meaning that they drive cables/amplifier inputs with ease.
The P20 is a cracking phono stage, we're still burning our demo unit in, but it's already highly recommended.
