Default RCA interconnect with Cat5 ?

I will be making speaker wires with Cat5 cables. Can I do the same for RCA interconnects?

thanks,

gychang

Sure. I have a 5' long pair running from phono-integrated, single pair of wires with rat shack connectors and braided plastic sheath.

Re: the RCA ("line level") cables / connections using CAT5 ... I would suggest that silver plated or pure silver CAT5/CAT6 wire is a very good choice for making RCA to RCA (or XLR to XLR) signal cables, especially if you can get the teflon coated stuff ... silver having less restance than just about any metal other than super conductors and Teflon being the insulator of choice for various reasons in audio. Silver cabling is available, GigaBit / 1000baseT / EtherNet for server farms and longer industrial strength installations, although it might be more pricey than silver audio cableing ... but it might be found in commercial remodel jobs as surplus for the costs of removal or online as "used"..

There should be nothing wrong with using "ordinary" copper CAT5 cable for audio signal cables, except that it is rather a combersome operation to strip and mate to RCA connectors ... and the results will probably not be any better than "regular" quality audio cabling.

(I use twisted pair #22 AWG silver with silver shielding and teflon insulation for all signal lines greater than a few feet in length = ... and don't bother seeking out CAT5.)

Since you appear to be in Irvine California, you should be in luck = many surplus wire/cable distributors in your area. ... I got my latest batch from an eBay reseller of stuff surplus in east LA. ...

http://www.euronet.nl/~mgw/diy/cabling/uk_4play_1.html = exactly right! ... teflon covered CAT5, silver if you camn find it ... gold plated connectors are a nice touch = some say this helps reduce conductivity questions at the connector, pretty in any case ... I use 'em when I cxan get 'em surplus = rare ...

I recently tried out some cat 5e interconnects with some tellurium copper rhodium plated RCA solderless plugs found in eBay. Days of expensive $$$ famous tailor maxes are done smoking my cash. Very good match with my 300b amp and tube output CD player. Concerned about long term oxidisation , trying out amtrans hookup wire (.4mm pos, .5mm return). Very very pleased, enough so as to try them out next in a 23 step dact type passive attenuator , but will use these captive to the attenuator itself, hoping that skipping a series of solder , jacks, and plugs and a switch can help this inexpensive punch well above its class. Will try dual outputs with cat 5 plenum to sub plate amp to render irrelevant any of my audio fool concerns about possible treble roll off . My experiences with cat 5 only include pleasant listening, though not quite as vivid and spacious as the amtrans. Best regards, it's great to see so many willing to try so much.

Of course you can make RCA interconnects with Cat5 cable.

But if the question was can you make good RCA interconnects this way, then the answer is a big NO.

The two import needs of an unbalanced (RCA) interconnect that are not met:

1] Low return wire (Shield) end to end resistance.
2] Good interference shielding.

Haven't had any shielding issues with homemade twisted pair interconnects. Did have issues with both wireworld Polaris and kimber kcag . You haven't been startled unless you were enjoying some Louis Armstrong only to have a tugboat radio requesting a bridge lift blast into your relax time at twice your listening volume! Possibly I've become less fussy about how good an interconnect needs to be after returning to vinyl one toe at a time. Is there a typical hot to return ratio of resistance for best results? Did hear about this but only in vaguest of terms, so tried about 80% higher resistance on hot lead than return with amtrans hookup wire. Seems fine, but didn't have extra cabling to try with identical hot neutral wires. Any opinions on conductor size ratios for interconnects are welcome here.
