Slightly disappointing NAD

What power supply are you using with these pedals?  

If it's a cheap one, then that may well be the source of the problem.  A friend of mine has a cheap generic power supply, and as soon as you add a pedal, the amp gets noisy.  

Worth considering

All rack gear and therefore mains powered. The Voodoo Lab is powered from a 9v switched mode supply but it's good quality and doesn't generate any noise with anything else.

After discussing this in depth with my local tech and taking @ICBM 's advice on board, I gave the rig a good listen again today and decided that, at gig levels, the hum is unlikely to be a problem so I'm going to leave it alone for now. In my home studio, the hum is very noticeable and it's noisier than any of my other amps but it's not that bad and at a gig it would just be background noise.

I could spend a lot of time and money chasing my tail over this and it's probably not worth it.
