I have the MA8900 and it runs very cool, even at high volumes (say 40 on the volume knob). Agree with the poster up thread that I would contact McIntosh directly as those temps seem high.
McIntosh MA9000 temperature in standby
Hello,
My system consists of McIntosh MA9000 with DA2 DAC, McIntosh MT10, Burmester BA31 and IFI Zen Streamer.
I noticed that the temperature of the integrated amplifier (heatsink) is about 102°F (39°C) at a room temperature of 79°F (26°C).
I performed the following test by increasing the volume in 3 steps:
1. 30% volume for 15 minutes: heatsink temperature -106°F (41°C)
2. 50% volume for 15 minutes: heatsink temperature -117°F (47°C)
3. 70% volume for about 15 minutes: heatsink temperature -145°F (62.7°C) - the power was cut off
I would like to know if 55°F (13°C) on top of the room temperature is normal for McIntosh amplifiers in standby.
Thank you in advance for your support
