After several hours of extensive use the Marantz is warm, but I recently looked at an Onkyo TX-NR1007 and it was hot enough to burn. This may not be a real world issue, but this type of heat can't be good for the internals in my opinion and a current owner of a TX-NR3008 has confirmed that the heat still exists. Are the Integra's better when it comes to heat?
As the Integra's are basicly the same setup as Onkyo, i think the heat will be the same.
If you compare the 7005 to the Onkyo 3008 or Integra 70.2, the 7005 has about 700 Watt and the Onkyo/Integra (can) use 1060 Watt
They both use 2 Independent Power Supply (one for sound and one for video) and the 80.2 has 4 !!..........
I use some computer fans on top of the Onkyo i had and that gave ne an internal temp of 26 to 28 C.
Without fans this goes up to 36 to 38 C.
Also the Onkyo/Integra's have 2 internal fans that will start working when the temp becomes to high but this will start to work above 65 C.
So even the units get hot to the feel, they are will within save temps.
And the most heat is produced by the HDMI board, not the audio section.
The HDMI board is on the back of the case so if you would put 2 or 3x 12cm fans at the back the unit will last for years and years (if you want....
I do not think the heat is an issue as Onkyo never changed any thing inside to get the heat down...............
