Back in the market again for a power amp. I got hold of a Behringer KM750, unfortunately the fan noise is not livable with in the lounge. It comes on at full blast when the amp is powered on and stays that way throughout. It looks like the fan would be fairly easily modded, but I'm not sure if I fancy trying that myself.
Interestingly, it has a ground lift switch on the back, which got rid of quite a lot of noise for me. The noise I get seems to be related to having a HTPC connected to the AVR via HDMI, then the AVR connected to the power amp via an RCA to 6.35mm cable.
So, I have ordered a Crown XLS 1502, to see what all the fuss is about. It looks like the fan only comes on when it senses heat, so in a home cinema use, with lots of ventilation, I am expecting it probably won't come on at all. However, no ground lift switch, so I may have to use the Behringer hum destroyer, but with 300 watts of headroom, I think I can afford to lose a little throughput.
@DougAP how did you get on with the hum destroyer and noise that you were experiencing? And do people generally leave the Crowns powered on permanently, I presume they have low power consumption when idle?
