I need a couple GOOD Power Supplies...Any Ideas?

 I own a pair of powered Bose Monitor-Speakers. The sound quality (for the price!) is very good; however, I have lost the factory power supply in a recent move. I am using ANOTHER 12-volt power supply but the problem is that the speakers are easily over-powered (or perhaps more correctly, easily distorted). This was not a problem with the factory PS (Power Supply). I am also planning on purchasing a Cambridge Audio DacMagic, which also has a poor PS.
Do high-quality PSs exist that I can use to clean-up the sound of the Bose and Cambridge products? I certainly do not mind spending $100 on a good PS versus the $12 units that come from the factory (both the Cambridge and Bose cost me $399).
I have never seen any mention of these online or in any magazine, but I do know that separate PSs are available for turnatables and other audio-accessories (like headphone-amps, DACs, iPod-docks, etc.). I DO plan on upgrading the whole audio system into not only a media-server but a full two-channel sound system (my PC being one of several sources), but not for a year or two (well, one piece at a time every few  months).

 Any advice or sources available for Power Supply upgrades would be highly appreciated, Thank you.

 The first place to start is if you're using a digital switching power supply, try substituting an analog power supply. This can lower the AC noise being broadcast into the rest of your system and clean up the spurious noise in the component hooked up to the power supply.
 
Several vendors such as Bolder Electronics and Channel Islands Audio offer analog power supplies for Squeezebox products.
 
As to what power supply is "best" depends on what you're hooking it up to, how "bad" the stock power supply is, and the rest of the components in your system.
