Power Conditioners Suited to Digital Front End

First, a question for you: what's your budget? Prices for power conditioners vary widely, so first you need to decide how much you can spend. Let the readers know, and it will help them to formulate helpful advice.

I want the cheapest thing that works well, but would pay $3000 if it was worth the improvement. I was thinking of a Power Plant 300, but am totally open to suggestions. I want to optimize the perfomance of by Transort & DAC. I did buy a $3,000 digital interconnect (Stealth) so if a conditioner made a real difference I would be willing to invest. I just feel a bit sceptical about the product category, but I'm open to new ideas on the subject. Thanks.

I've had great results with Audio Magic conditioners on my source/pre's.

I use the Power Wing from http://www.audioexcellenceaz.com/powerwing.htm with my Accustic Arts transport and dac.

I would not use the Power Plant 300; had one, too noisy, and blew fuses too often. For my digital front end, in two systems, I now use Ensemble Isolinks. I have one Isolink Duo, which can handle two components; and several single Isolinks which handle one front-end component apiece. This power conditioning provided the single best improvement I've ever made to both my "big" system and my living room system. I bought the Isolinks used on this site and they are a great great addition to my two systems. I also use Ensemble power cords with them, and Ensemble interconnects as much as possible in both systems. I have tried many brands of cables but Ensemble provided the absolute best value and sound for my wallet and tastes. They are a Swiss company and their products are built like one would expect from the Swiss! Perfectionist.
