Power conditioning for computer audio


What are the best types of power conditioners/regenerators for PC audio?

I was about to buy a PS Audio regenerator but then read that these devices don't do anything about the high-frequency noise put back into the line by computers and digital sources. So I'm not so sure.

My digital equipment is a Mac Mini and Audio Note & MiniMax DACs. (And also a Sony 5400.)

Excellent suggestion by Elizabeth. Fair-Rite is a leading ferrite manufacturer. I suspect that one of their "Round Cable Snap-Its" would be suitable, chosen to fit the particular cable diameter. Hopefully one of the distributors they list, such as Mouser, Newark, or Arrow, sells them in small quantities.

This Fair-Rite paper will tell you more than you will want to know about these things.

Happy holidays!

Of course, if you stream wirelessly to a network player, it may not matter. Flame away!!!
Thanks both of you for that suggestion. Almarg, it seems there is no way to order direct from them, at least from the web site. I've written them about a direct order. I will look for AudioQuest too.

So, does improvement from these things typically fall into the "I think I hear something" category or the "there is a definite improvement" category?

I'd thought I'd heard it all and was not aware of these things.
