McIntosh hum problem

Any of you MAC people own a MCD 751 CD Transport and MDA 700 D/A Converter combo? I do and both hum, wondered if any others with same problem? The converter hums louder and MAC gave me a new power transformer for it, but did not help. The hum is from the units themselves vs. speaker hum. Any way to reduce the hum. Any advice appreciated.

Ligi,
I tried different outlets, cheater plugs and no change. Units are in a different room well away from cable TV. Seems to be a problem with noisy power transformers. Thanks to all for your advice.
