I've recently purchased the Jamo DVR50 and A305 PDD system, and jolly impressed I am too - sound and picture are both excellent and the whole system looks superb. There is however one thing vexing me, and I'd appreciate knowing whether other users are experiencing the same thing or whether my DVR50 needs to be looked at. After about 30 minutes or so of use, either on DVD play or for the TV (but not for the radio), what can only be described as a whirring noise, rather like the sound of what could be an internal fan, starts in the main unit. Its not that loud, but its just about audible enough to be annoying during quieter moments in a DVD. Whilst the unit does get very hot if I put my digital box on it, it doesn't feel overly hot for a piece of electronics when its standing by itself. The noise still happens though even when there isn't anything on top of the unit. Anyone else getting the same noise, or should I be getting it looked at before it overheats and barbeques my flat.
