Denon AVR-3802: Has anyone noticed how quickly this amp heats up?

    I use to own a Marantz SR-5200 amp and no matter how long it was on for, it would stay relatively warm at most even after being on for over 6 hours!

    With my new AVR-3802 however, I have noticed straight away that this amp tends to heat up rather more quicky than the SR-5200. I was very supprised by this especially when Denon advertised the 3802 as having huge transformers which deliver equal power to 7 channels.

    Have any of the 3802 owners noticed this besides me?

    BTW I'm currently only using a 5.1 setup and under 'power management' I have chosen 'multi-surround' as opposed to 'surround-back' and under 'speaker configurations' I have set the surround channel 'B' to 'none'.

    The Denons do run quite warm. As long as you have plenty of ventilation around them, they´re fine.

    Not that it would make much difference but I had my 3801 set to Surround back rather than multiroom, mind you I was using the extra speakers.

    If you have the option in speaker setup to select no surround back speakers then use that. (Cant remember myself!!:eek: )

    I have the 2802 and that heats up pretty quick. My CD player is stacked up on top of it and that picks up the heat and refuses to play some disks (it searches endlessly). I need to sort out my ventilation around my components.

    Denon say 10 cm all round. I have got 6, but have open back and sides so I think I am OK. Stacking on your 2802 seems like a bad idea

    Manual states at 10cm ventilation but goes to say amp has thermal cut out. I noticed it get hot as well and can only muster 6cm distance above my amp,but Denon may well be catering for all climates in that statement in their manual. Chill out and enjoy !!

    I was thinking about buying the Denon as a replacement for my Sony DA50ES but am concerned about potential heat problems.

    The cabinet I have would allow 2cm above the amp and 4cm either side but an open back and a glass front. There will be a wooden shelf above and below.

    Can anyone advise whether the Denon would be OK in these circumstances, given the 10cm clearance suggested in the manual?

    I have a 3802 at the bottom of a wooden hi-fi rack. There is minimal clearance (1-2mm) at the sides, but the back is open and there's about 50mm gap to a wooden shelf above. As there are no vent holes in the sides I don't believe it's a problem. I too have a glass door, but I tend to leave this open when it's on, just to improve the air flow. I've also got (in order above the AVR) a VCR, a cable box, and a DVD player. I've had no overheating problems, although the amp does kick out quite a bit of heat.

    I have the 3801 and there are a small line of vent holes on the left hand side, are these omitted on the 3802?
