why the PC change the tonal on my gears.


I bought a couple brand new Prelude PCs and decided to use one on my intergrated amp. The whole system is fairly new and the sound is clean and a little bright and sharp on vocal but extremely details in the high with this PC. After A/B switching speakers, intergrated,CDP with the same ICs ( Hero) and the same PC,the sound still not the way it was ( warm, open and a little on the dark side), I switch back to the stock PC and the system sounds just the way I wanted. I don't believe in PCs effects the sound that much but I now I see PCs can actually alter the tonal of my gears. Any thoughts anyone?

Andrewdoan, yes, a power cord does take time to burn in, however 700 hours seems a bit excessive. From my experiences, you usually get a good idea of how a p/c will sound right out of the box. Generally, the cord's sound will change a bit over time, as it 'settles', but I've never heard a night and day difference as some folks have said. Usually, if a cord I've heard is 'in the ballpark', it can sound better over time. However, I've never heard a cord sound forward, have sharp glare, and too detail turn into a warm, sweet cord with time.
Sometimes burn in can take the edge off, but if the initial reaction is that negative, I don't think that's the p/c for you. There are many other good cords out there. It depends on what kind of sound you are looking for. There is a thread on the AudiogoN forums called 'Power Cord Flavors'. Maybe you could get some background reading stuff like this. Sure, it is not the Bible, and opinions will vary a bit on what aspects they look for in a p/c, but it will give you some ground work, a place to start.

Happy listening,

Does any one can think of a reason if the PS prelude due to its shield contruction can damage the components in the long run ? I have read somewhere that some of the after-market PCs can restrict the AC juice to feed the components that can result the negative effects in sound quality in short term and damage the components in a long term usage.
