Hi.
My findings is that the best PC for an amp is not necessary the best for a transport. And if a PC can change the sound it will be necessary to test it everywhere in the system. And I think that it is not given that any upgrade PC will be better because it cost more . I use a cheap brand called Nimak for most of my High-end system. But they're all different gauges. I also use a cheap Viborg on my pre-amp instead of a Ps Audio ac12. The price for the Ps Audio ac12 in Norway is 10 times more than the preferred Viborg.
In my system it's more easy to hear difference between PC than interconnects.
What I don't understand is that how these PC can change the sound given that the gauge is correct. If anyone can explain how it works it would be great.
Shadow, I have been using a Cullen Gold PC for about 2 weeks. I am using it on my Pass amp. I definitely feel that the background is blacker. I am going to try a Cullen Crossover for my preamp. I think that I will eventually replace the cords on my DAC, audio computer and LPS for my Regen with Cullen cables.
Why would you think that cables (some of the most stable things in a hi-fi system) after a long period would cause the change in sound?
There are so, so many more likely candidates.
It's been my experience, and others here have said much the same thing, that one particular brand/model of PC does not sound good everywhere. What works best on the amp is not necessarily best on the CD player, and visa versa.
Unfortunately that means playing with PC's is a trial and error process. Your best bet is to find a manufacturer that allows demo's and returns, or borrow cables from other audiophile friends. Alternately, go to the used market and pick up a few things on the cheap. If they don't work out anywhere you can likely get your $ back on a resale.
And yes, cords do break in and settle over time, so a 15 minute audition is not the way to make a decision on these things.
Brian......It has been my experience the best bang for performance improvement comes with premium power cables installed on your power amplifier(s). Having said that, I don't believe it is in the best interest of top notch sound system performance to mix and match various power cables, or interconnects for that matter. I began with stock power cables on all components and now have a total of 14 two meter Wireworld Silver Electra power cables feeding all components in two separate systems including the PS Audio Power Plant Premier AC regenerator in the living room system and the PurePower 2000 AC regenerator in the studio system. In both systems the biggest performance jump happened when I installed the Silver Eclipse power cables on the power amplifiers. After that there was incremental improvements in sound stage and overall clarity as I added additional Silver Eclipse power cable to the preamplifiers and source components. The combined synergy of the systems being cabled entirely with like interconnects and power cables has elevated both sound systems performance to a level that I don't think would be as resolving and dynamic had I not gone all in.
