Question on the Purist Audio Limited Edition P/C's


.....I first added one of these power cords to my amp and yes there was a noticeable positive sonic difference. I just added a second one to my pre-amp and that too made a positive sonic difference, however, not as much as when I added one to the amp. So, my question is, is there a diminishing return when you add more of these very expensive power cords to your system ???? I still have a dac and transport and was wondering whether it would be sonically worth it to get two more and round out the whole system with them ??? I would appreciate answers from Audiogon members who own and have these cables in their system. Thanks ..........

What power cords are you "upgrading" from? And why did you decide to start at the amp and then next to the preamp? My experience with power cords is that the digital components and phono/line stages react far more to power cords than do amps.

The logical thing to do would be to try a single new cord in the system, at each of the 4 places and leave the other 3 original in the system. You do not need to live with this change for days or weeks. The change should be noticeable instantly. Following this experiment 4 times, you will have an idea as to what components in the system react the most to the cord change. Then you can decide what is the additive benefit of 2 or 3 or 4 of these new cords.

Thank you for your responses....my entire system is Purist Audio 20th Anniversary cables. So, the cables I am '' repalcing '' are PAD's 20 Anniversary's.....I have always started with the pieces that have the bigger(est) power supplies with any changes in power cords. I was hoping to hear from members who have or who are using this paricular power cords in their system.
