Default Cheap, simple and very good diy interconnects

While it didn't seem like a whole lot of of people took me seriosly when I told you about the "GainWire" ( http://diyaudio.com/forums/showthrea...921#post287921 ) I'm hoping you will this time.

Here's a cheap, easy to make and very good performing interconnect:

1. Get some 30AWG "Wirewrap wire". The one you want is made of silvered solid core copper with teflon coating. Here's an example http://www.elfa.se/elfa/produkter/no/178479.htm

Price is about 25 cents/meter

This cable you can also use as internal signal and power wiring in all line-level equipment.


2. Get your favourite RCA/XLR connectors (I use Neutrik's -very good and reasonably priced)

Price: RCA $2 a piece, XLR=$7.

3. Cut to length, twist with a hand-drill and solder your plugs (solder with some percentage of silver is recommended). I also use some Polyolefin heatshrink inside the plugs to make the strain relief effective.


So, there you are:

1m pair of RCA cables: ~$10

1m pair of XLR cables: ~$30

For those who are interested; the capacitance is about 20pF/m. If you desire a more rugged cable, you can thread the twisted pairs through some PTFE tube of suitable diameter.

If you require a screened version, you can get some screened heatshrink tubing http://www.elfa.se/elfa/produkter/no/177861.htm

Maybe you need some glasses

Yes they are thin, but also pretty tough because of the teflon coating. You want thin cables to achieve high bandwith.

I forgot to mention; it took me about 2 hours to make these two sets..

Terrible you say? The cables I made sounds really nice, and they haven't even burned in yet. They do however sound a tiny little bit brighter than for example my GainWire (made the same way, but with 24AWG magnet wire and PTFE tubing). These are also a little clearer/more revealing. Maybe if you have a overly bright sounding system or equipment that should be masked by some cable-effects this one is not for you

edit: with my el cheapo/xbzls/balanced gainclone I prefered the GainWire-interconnects, but with the pacific/bzls/soz I think this one is much better. Haven't found a catchy name yet though

Mad_K, all

I've done the same , using the same wire-wrap wire from Elfa,
the resulting cables sound pretty good, very open
I soldered mine directly to the amplifiers, no phono plugs.

For those who are interested; the capacitance is about 20pF/m.
Thanks for that , I wasn't sure

cheers,

-You're welcome. They where measured with a very expensive LCR meter at work, and showed 20-30pF depending on how tight it was twisted.

Glad you like it too; I'm getting a little ****ed when I think about that people feel they need to buy cables for thousands of dollars. (I'm also a little ****ed at myself -I used to be one of those people until I escaped from Audio Hell )

20 guage is too thick... i've used 33 guage with PVC from Radio Shack, the teflon is better (but more expensive). you can play with geometry a bit and get further improvements -- ie wrap the wire around teflon core from high end cable-vision wire (it is some work to remove the outer cover, braid & inner conductor).
