Linear Power Supply for Netgear FS-108 Switch

I've heard a linear power supply for the FS-108 Switch will improve audio quality and keep out noise.  Can anyone recommend a reasonably priced LPS for this switch, which is 9V, .54A input.  Thanks,

+1 Small Green Computer....quality products with an accessible owner. I'd call Andrew Gillis and ask his opinion
Thanks for the pointer to Small Green Computer. I will check them out.
Small Green Computer. Made in New Hampshire and maybe $100-$150.

Other less expensive options are usually all shipped from China at $75-$90.
Not worth the hassle.

Or, Keces Audio if you want to pay $350 for a really cool looking box.

I’ve been looking into the same thing.  Don’t know but am hearing and reading that unlike amps, and other gear like my preamp, a LPS is actually a detriment and you must use a switcher with a switch.   

I have a friend who has a netgear switch for his rig and I’ll ask him and try to get back to you here.
