I've tried everything to get rid of the hum in my LD Mk III. The hum is there even if connected to a two prong. Not loud, but it's there. Do any of those small devices work to get rid of hum without losing frequency response?
Besides the hum it sounds great. Any suggestions?

I have noticed with my own tube amp that some tubes have more hum than others.  You might want to try switching tubes and see if that helps.

What does your setup consist of?  USB from PC to DAC?  CDP to amp?
