I have the Bryston B100 SST (with DAC and phono) driving Harbeth SHL5 and am very happy with the combo. I have not heard RWA gear but I have compared the Bryston B100 with the Accuphase E-450 and the Bryston held its own extremely well! If you d have the opportunity, the Bryston B100 should definitely be in your shortlist!
