I am using the Oracle AC 2 power cord alone, which has their Z stabilizer circuitry and power correction networks onboard tuned for audio frequencies (50-60hz). This is the only product that has ever made good on what power conditioners are supposed to do...it is so incredible that I can hardly comprehend how a PC could make such a complete and total transformation in the sound of a system. This was the last link of my audio system to be completed. I have owned $80k rigs that couldn't have competed with my humble system currently...the MIT stuff has altered my entire outlook on what is possible with 2 channel audio. By the way, I ordered the PC for a 30 day demo...it took me less than 1 day to realize that I had been given a glimpse of the "Holy Audio Grail"...to be in the presence of music at home and on command:)
