PS Audio P500 Yes? -No?

I had a p-600 that I used only for front end gear, it worked great. The p-600 never ran hot just warm to the touch. I recently sold the p-600 and in it's place added the p-500 as it's now placed on my equipment rack. The p-500 runs a bit warmer than my old p-600 I think due to the smaller chassis design and less output but still works great with my equipment. I consume about 200 watts or approx. 47% of the p-500. I use the sine wave mode most of the time and every now and then I use tube wave. I keep the voltage set at 120 volts as this yields the best sound. On my p-600 I had the multi wave II plus (cleaning thing) my tube preamp made a wierd noise when I used that feature, don't no why but I did like the result it made but stopped using the cleaning feature as I didn't want to damage my tube preamp. I have been using power plants for the past three years and when I made the switch from the p-600 to the p-500 and was without a power plant for a few days that's when I really noticed how much they really do improve the sound. For my system I have a dedicate line > porter port > p-500 > power director > Preamp, phono stage, TT motor, D/A and transport as this is the best set up for me. As with my amps I don't connect them to the power plant but use a UPC 200 for each amp istead and a dedicated line for each UPC 200. If you buy used and don't like it you can always sell it and get most if not all your money back. Happy Listening!

Thank you for your responses. Very helpful. I believe I'm going to get the P500. Any other comments are very appreciated.

p-500 is great product . I have been using one on my front end digital gear for over a year. I prefer the sine 60hz setting for good clean regenerated ac but the MW settings are interesting and fun to try. You will hear specific audiable differences in the MW II settings.Some good some not so good. I believe it differs with electronics that are attached, As suggested before this product not designed for amps.

I have had my P500 for about 2+ months now and can honestly say that it MAKES A VERY REAL DIFFERENCE IN THE QUALITY OF WHAT I AM HEARING ON MY SYSTEM. I am thinking of getting a second unit to fully cover my front end gear. Wonderful investment for me.
