I have the P300 with the new Multiwave upgrade. If there is an alternative I am not aware of it. Even before the Multiwave, no power conditioner or cord I have used even came close. And why should it? Any of the aformentioned products still use what comes out of the walls while the P300 creates its own. The solution is simple, elegant and very effective. I never realized how much impact the power supply was to audio components until I had the P300 in my system. For $1000 it is CHEAP money in this crazy audiophile world of 2K interconnects. BTW the Multiwave improved (and amazed me)the sound even more than I thought possible. This is an excellent product for those with ears to hear.
