    I've now used the Pro-Ject Stereo Box RS for a couple of months and I'm very impressed by the power and quality of the sound.
    Using it solely for vinyl playback through a Michell Gyrodec, it's a huge step up from my old system and even some new recent integrated amps that I have tested prior to purchasing.
    Neutral, detailed, powerful, it packs a beautiful punch that drives my floorstanding Tannoy XT8F to incredible heights, not losing any composure during the process, even at loud volumes.
    I can't recommend it enough.
