Smooth Highs and Deep Bass


Looking for advise on an RCA interconnect that can tame the digital edge from my SS ARC CD3 mkII and also has low-end extension.

System is:
Rogue Preseus Magnum preamp (w/ Mullards), Sunfire 300, Gallo Classico CL-3’s, Blue Circle Power conditioning

Cables are:
Purist Audio Museous IC from pre to amp
Purist Audio Aqueous speaker cables
Audience PowerChords

For the CDP, I have tried Cardas Parsec and Clear Sky; did a great job of smoothing out the highs, but had no low-end.
Cardas Clear Light; too harsh, but great dynamics.
Cardas Golden Reference; too coloured.
Purist Museous; highs were not smooth enough, great dynamics.

Budget is under $500 (1 meter), not looking for a detailed cable, system already has detail.
Need smooth highs, open, with deep low-end. I’m already renting from the Cable Company and need additional assistance.

Thanks, akg, I value you insightful comments.
System synergy does matter and one size does not fit all, but my real goal is to ask other members if they have found cables that help soften the "edge of digital output without sacrificing dynamics. (I've already found the right PC).

I love the sound of my current system; the Purist Audio cables have great synergy with my components, just trying to tweak the digital. I need some advise; I think the Cable Co. is out of ideas.
akg is partially right, but also partially wrong. I doubt there's a person on these boards who doesn't recognize the roles of system synergy and personal preference in putting together a system that works for them. And I'm sure everyone would agree that in the end you're going to have to listen to whatever you can and make your own decision based on your own ears. Where I think he's off the mark is with his second paragraph. I linked to the Stealth PGS not because it's my personal favourite -- not at all. And while I have owned it (a couple of times actually), I haven't owned a pair in quite some time. But on the occasions that I have owned it, it has proven to fit the description that you've asked for. And that's in more than one system. Moreover, the many reports that can be found on the many audio boards seem to agree that it has smooth highs -- for some, too smooth. So my decision to mention the PGS is based not simply on my desire to push my personal fave, which it isn't, but to bring to your attention a cable that many audiophiles agree has a smooth top end. Will they work in your system to smooth your top end? That I can't tell you. But the cables reputation, and also my own experience with it, suggests that it might be one cable worth considering in your quest. And in the endless sea of cables and cable choice, isn't it good to get a few suggestions where you might start your search? I can also agree with the Audio Zen suggestion. Nicely warm cables, without being overly coloured, but still nicely detailed. I've also owned the Darwin cables. While they are extended, I'm not sure they'll give you much relief from the digititus problem. They might even exacerbate it. In a cash no object solution, I might suggest looking for a new digital source. But in the real world, a cable might have to do.
Siltech Royal Signature series cables are very smooth and have notably good bass. They have wonderful tonal richness & also sound dead quiet. Finally they have heirloom build quality.
Lowrider, one thing that could be contributing to the "digital edge" you are perceiving, and also to the high degree of cable sensitivity you’ve described, is a ground loop between the CDP and the preamp.  A simple experiment that might be worth trying is to temporarily put a cheater plug on the power cord of the CDP, to defeat its safety ground connection.

If that seems to help, my next suggestion would be to remove the cheater plug and put a suitably chosen Jensen Transformer (ca. $275) between the CDP and the preamp.

Good luck.  Best regards,

That's all I'm asking for.  Thank you for putting it into such a concise comment.
