The Xtension 10 chassis is made from MDF filled with metal sand, that gives high mass and is non-resonant. Magnetic feet, which decouple the main plinth from its base, are combined with a weighty 22 kg total turntable mass. With these two magnets located in the feet, the turntable is practically floating.The result is a unique combination of mass loaded and floating turntable design principles. Instead of the old standard adoption of pure metal used for the main platter, Pro-Ject have found a perfect alloy which Pro-Ject damped on the inner side with Sorbothane®. Additionally Pro-Ject have glued recycled Vinyl records to the top (which act as a perfect mat) and bake this sandwich before precision balancing it. The final product subsequently benefits from a wonderfully resonance-free, heavy platter, that runs ultrasilently on an inverted ceramic ball bearing with magnetic suspension. The Pro-Ject 10 Evolution with its tonearm base also benefits from high-mass technologies, and is isolated from the main board by a sheet of Sorbothane®. To use this tonearm with a wide range of top quality phono cartridges, from 4 to 14 Grams it comes with a set of 4 different Sorbothane®- damped counterweights. Pro-Ject Audio Systems offers their high-end turntables with premium 5pin > RCA unbalanced arm cable or by request with premium balanced 5pin > XLR connection to Pro-Ject Phono Box RS preamplifier. Phono Box RS offers balanced phono inputs, what guarantees superior results in high-end vinyl reproduction with a balanced signal source. NOTE: The signal source and the receiving device have to be equipped with balanced connections. Transmission of audio signals in a balanced mode reduce the influence of interference due to external stray electric fields significantly.
