Digital Coax Cable for Unbalanced Interconnects? (1 Viewer)

[MWestyn]

Just got a Rotel RMB-1075, it's currently mated up to a Marantz SR7300 but that will be replaced by a Rotel RSP-1066 in a few weeks.

I'm currently using digital coax cables (AR Pro Series) as interconnects honestly because it's all I had on-hand when my 1066 got here. What I'm curious about is if this is a good choice or not given the wire core. They have a solid 99.97% pure, oxygen-free, copper center conductor wil 95% copper braids and 100% aluminum Mylar foil shielding. I compared these to a set of AR Pro Series stereo pair, they are almost the same but feature a twisted pair multistrand core instead of a solid one. Which is better to use for connecting my pre/pro to the unblanced amp input?

Anyway, I'm looking for suggestions on some good interconnects for the unbalanced line in if my choices are poor.

I'm fairly savvy with HT components but I never stopped to think about these interconnects.

Thanks!

These are better then the typical RCA interconnects. For example, if you look at www.bluejeanscable.com they use Beldin and Canare 75 ohm coax cable for their interconnect cables.

Huh...AR also makes interconnects made specifically for 5.1 setups (5 cables, color coded for easy hookup)and they are much like the composites except have a heftier 22 gauge 99% twisted pair...seems like that's almost like having a twisted pair of the solid core digital coax. Any thoughts on that?

Thanks alot guys!

Go to the tweaks section and read about cables. It kind of boils down to copper is copper and conducts electricity the same weather is braided, solid, stranded, twisted...

You can even make good quality DIY cables by using RG-6 cable, but make sure it is solid copper and not the type with an aluminum center.

I think you are mixing up HTF with AVS forum. That's what the "experts" claim in AVS, copper is copper and digital is digital.

Damn! You're right. I get confused so easily. I keep forgetting superior copper acts superior with superior electrons. It gets really bad when you let cables cross each other, lay on the floor, and don't use the green marker on your CD.

Thanks guys.

Yeah, I wasn't so much trying to understand which is better as much as which is commonly used for unbalanced lines...I did get my head spinning thinking about all of this though.

I do work in the computer field so I know a bit about cables, attenuation, etc. But it's easy to start over-thinking.

I appreciate your input and I think I will just A/B some cables but I'm sure I won't find any actual perceivable difference.

Either way I'm happy with the system.

Man, that's the truth. There's so much BS in this hobby it's hard to sift through it sometimes. Some of the marketing that goes on is Trula amazing. Reference some scientific principle even if it's not accurate to say something has better performance. I know I've fallen prey to this more times than I care to think about.
