Regular interconnect or digital?

Not knowing your equipment that makes it very hard. If you have audiophile equipment I definitely recommend Transparent. Cardas is a tad warm, which enhances most systems. DH Labs, good budget interconnects.

boxcarman:  technically, I'm sure that what's been said here is true but you asked about sound quality.  With regards to that only, you can certainly use a regular interconnect and get at-least comparable SQ.  When I purchased my first separate DAC in many years a couple years back, I used a Black Mountain pinnacle silver interconnect with RCA's on one end and XLR's on the other I had in the cable drawer.  The transport is a Bel Canto Cdt-3.  I was getting better sound with this combo than the Consonace Droplet 5.0 and Raysonic 228 I previously had.  Of course, I wanted a digital cable so I found an Acoustic Zen MC2 and gave that a try.  The Black Mountain interconnect was more vivid and precise.  There wasn't an area where I felt the AZ cable was better so I re-sold it and later tried a Neotech NEVD with Oyaide BNC and Xhadow RCA plugs.  It's 6 one way, half a dozen the other.  There are difference but really, they are equally good.  

Icherepkai,  I had to compare different cables and the most revealing sounds came from a medium priced Audioquest digital coax cable 1.5 meters.  Not just a small difference and now I am re-visiting all my old favorites [again].  Fun.

Hello boxcarman - Digital cables in my experience should be at least 1.25 -1.5 meters long and cable dressing is important. Keeping the cables from touching each other is key to best performance. I used a very good cable for a while on my Naim nDAC. TheCableCompany sells The Silverstar! mk II By Black Cat Cable. Great bass and smooth high frequencies. I had to move up to the Chord Company’s Signature Super ARAY Digital Coax to out play it. Not all coaxial cables sound the same, in my experience.

I own both Cullen and Signal Cable digital cables - 5’ in both cases.  Both are good but in my system I prefer the Signal Cable which at $64 is a bargain.
