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.
