Περιγραφή
Four specific characteristics make this a true high-end preamplifier: 1. Fully balanced double mono design 2.class-A circuitry with no negative feedback 3. Tube output stage 4. Separate power supply as an upgrade option for further improved sound quality.
Pre Box RS offers 3-dimensional sound-staging, perfect micro dynamics and ultimate resolution combined with flexibility to use XLR and RCA sources. Perfectly combined with Pro-Ject Amp Box RS amplifiers, Pre Box RS will give pure sound experience, that the real audiophile is looking for. Pre Box RS utilises a luxury casing, that is available in silver or black finish.
