If its Transformer Hum it possible it is Frequency related

the PurePower Regenerators have microprocessor adjustment to eliminate that.

I have NAIM UK PSU's that hummed along with the music.

The PP's were the saviour.

Good Luck

Has anyone tried a DC offset unit like this from Kemp to handle transformer hum? I wondered to check if this would work for a 211 amp with some mechanical transformer hum I have.

I have not tried the Kemp but have used the Emotiva CMX-2. It works perfectly and it is not expensive.

That said, you should try to find and eliminate the cause of DC offset in your mains feed.
It can be an indicator of loose connections in the mains panel or a branch circuit.
Usually the culprit is switch mode power supply 'bricks' or other devices with electronic power supplies.
If it is intermittent, look for microwave oven use.
Good luck,
Tom
