Pro-Ject Amp Box RS Amplifier + Power Box RS Amp Power Supply -

The Amp Box RS is high-quality solid-state amplifier with a really great and accurate sound, which is complemented by a tube input buffer. I'm selling this as a combination along with its matching toroidal power supply that increases the depth and detail of sound, as well as almost doubling the standard power output of the amplifier.
The units are both in excellent condition, coming from a smoke-free environment, and include all original accessories. Please note that I originally picked up the amp from a friend locally, and while the box has seen better days, the unit itself is pristine.
Manafacturer Description Ultimate high-end sound with high efficiency in a compact luxury casing! Four specific characteristics make this a true high-end amplifier:
1. Fully balanced double mono design 2. Highly efficient energy saving PWM modules 3. Tube buffer input stage 4. Upgrade option PS Box RS for more power and further improved sound quality
Amp Box RS offers 3-dimensional sound-staging, perfect micro dynamics and ultimate resolution combined with high power output and 2 ohm capability and also is the perfect solution for Bi– or Tri-Amping applications.  Amp Box RS is the perfect companion for Pre Box RS and will give pure sound experience, that the real audiophile is looking for. Because of its heat emission Amp Box RS luxury casing, which is available in silver or black finish, should not be combined with Design Box Acryl.
The addition of linear power supply Power Box RS Amp adds even more depth and lets you hear all microscopic fine detail.
