Linear power supply consists of a big toroidal transformer with shielding between primary and secondary winding which acts as an isolation transformer and avoids penetration of interferences from mains into amplifier. This transformer has a big power reserve, compared to a standard power adaptor. It has very low output impedance and in combination with large filtration capability it can easily manage required power of one stereo amplifier or two mono amplifiers. Advice: To avoid magnetic interference do not stack amplifier and Power Box RS Amp!  

As every amplifier, also digital ones, are sensitive for good quality of energy they are powered with. It is proven by extensive listening tests, that linear power supplies improve the sound of digital amplifiers significantly. This is what all well known high-end manufacturers already realised. Therefore Power Box RS Amp offers a big sound upgrade at an affordable price!

Huge Difference!

I bought the Amp box, Uni 4 way & Phono power box upgrades for my Pro-ject RS LIne kit.

There was an immediate change to the Sound Stage being presented in all areas. The sonic ceiling was lift and the floor dropped. The stage was bigger more defined and better placed in "space". Particularly the phone front end.

Would recommend this as great upgrade if you have this kit.
