My Cyrus 6 is biwired to a pair of Monitor Audio BR5. The amps cuts out at around 45% of the full volume. I know the amp has a protection system but really annoying. Should I be looking at new speakers with more grunt or a new amp. Service from Cyrus is around £225, so now more then the amp is worth. The amp also runs very hot after 30 mins of playing. It has around 30cm of space around it for ventilation and I have moved it into open space but still gets very hot.
