Low-noise mains power for my device?

[ggking7]

I'd like to power the following device with very low-noise mains power:

Ultravox - SGD70.00 : Welcome to the diyparadise e-store!

Is there a low-noise linear power supply available that would work?

Use any power supply designed for instrumentation purposes.

That sounds like a good idea. Is there a good brand or two that come to mind?

Which do you think would sound better between an instrumentation power supply and batteries?
