Proceed AMP-2 & AMP-3 operating temps

Hi gang!

I've had my AMP-2 for 6+ years and love it. I just purchased an AMP-3 on eBay and received it this weekend. This paves the way to upgrade my HK AVR-430 with a Rotel ssp.

With my first couple of days with the AMP-3, I've noticed that it runs significantly hotter than my AMP-2. The 3 is driving center and the rears while the 2 is driving my front L & R. I'll actual temperature readings tonight.

Should I be concerned about this? Are there any Proceed users out there who can give any feedback on how warm or hot their AMP's run?

Thank you!

Hi Duane, thank you for your response. I'm not sure what you mean by the fact that the bias might be off.

I did forget to mention that I'm running balanced cables to the AMP-2 and standard RCA's into the AMP-3. Might that make a difference?

Oh this is a bit embarrassing: I leave the AMP-3 on all of the time and the AMP-2 was being triggered from my Proceed PRE. This accounted for some of the temperature difference. I've now had both amps on for the past 48 hours and there is still a difference between them - the 3 is almost too hot to keep your hand on it, but the 2 is "just warm". I'll experiment to see if there is any sound difference when driving the fronts with the hot amp-3.

Thanks again Duane.
