Hello All,
Did an Icepower 1200AS1 Amp custom build as a pair of monoblocks. All good until I completed the project. The problem is that the power supply transformers vibrate at 60Hz. There is a clear hum if you put your ear near the amps. This does not propagate to the output. However, this, in my view, is a serious quality issue with IcePower and they have not acknowledged the issue nor replaced the boards.
I also have a pair of Nord NC500 monoblocks and they are dead quiet, dark as night and my A/B comparison vial listening is that there is no difference sound-wise, but I will definitely not recommend IcePower as their quality is suspect and any board with transformer mechanical vibration and hum is totally unacceptable. I am flabbergasted at the lack of such basic quality control. It would seem to me, based on my experience, that Hypex is far superior in their quality and build.
I have attached a couple of pictures.
Thank you
