Will an after market PC improve the sound of CDP??


There is a cable component that some of us may take for granted That is, 'AFTERMARKET" power cords. The issue is to what degree they may influence the sound of a component they are used with.

I use a Shunyata "Diamondback" PC with my Rega Apollo player. I may have compared this PC with the standard PC supplied with the Apollo a few times and discerned some improvement, but not enough to run out to "recable" what components I had at the time

Therefore, are there some aftermarket PC's that offer a noticeable improvement in the sound quality of a CDP?? I realize that with IC's, compatibility with a particular component is a matter of time consuming trial and error. However, is the degree of improvement with an aftermarket PC be as noticeable as with IC's, and require as much trial and error??

PC's require as much trial and error as IC's. There are no easy answer to your questions. Any aftermarket PC can improve the sound of your CDP and also negatively impact the sound too. You have to do the listening trials.
To Lowrider, I did try the Shunyata on my new Rogue hybrid integrated, with little to no discernible improvement. The Shuyaya's IEC plug is a plastic piece of crap and often gets loose and falls out of the back of the Apollo

Interestingly, a few years back, I bought an Acoustic Zen Tsumani Plus PC that was recommended by a TAS reviewer who claimed it provided better overall sound. I tried it once or twice on the Rega CDP, and concluded it better served my pre-amp at the time, and now my integrated as their PC. I could hear a much better presentation. The Shunyata worked poorly with my previous separates and integrated amps
Yeah, that Diamondback will never help the amp, it's also a budget cable in the Shunyata line.
For your CDP, the Pangea line is so inexpensive and so much better than stock it's worth trying.

There's also the AC-14XL for $150 with 30 day trial. Also try looking in the archives to see what others are using.
If your Rogue cable is anything like mine, it's piss poor with no bass extension. I'm also in the middle of a PC upgrade and have been doing shoot-outs with several cables.
Give a Triode Wire Lab cord a try. Pete offers a trial period for home audition.
I agree with both Lowrider57 and Foster_9, PC's differences can be very noticeable, but are also very system dependent. Aftermarket PC's can vary the sound quite a bit, just as much as interconnects, though I would not always call it an improvement. Different is not always better. You have to listen for yourself.
