Help me build speaker cables please!


Howdy!
I’m looking for input on some home brewed speaker cables. I’m currently using cables I made from braiding 8 lengths of CAT 5 plenum cable together. They’re terminated in silver plated BFA bananas and set up as a biwire configuration at the speaker end. I love their sound, but think I’m ready to try something made from higher grade metal. I’ve been doing a lot with silver in my system and have loved the change in sound almost every time I’ve gone from Cu to Ag. The only place I like Cu better is in the PCs for my amps. That said, I’m leaning heavily towards making a set of solid silver speaker cables, using .999 silver wire from Rio grande. I’ll insulated them with teflon spaghetti tubing and possibly terminate them with silver plated BFAs.

Where I’d love some input is here: do I do one run of 10awg, or biwire 12awg to the woofers, 14awg to the tweeters and mids? I’m using a dared tube preamp and monoblock Ghent audio class D amps (500w into 4 ohm) which drive floor standing RBH 1266 SE/R speakers. They are 4 ohm and have side firing 12" speakers. They like a lot of juice and sound their best when given what they want, hence my desire for large diameter cables.

Cost wise, it’s only $50 more expensive to biwire. I liked the change in sound when I first biwired, but I also went from blue jeans twisted pair 12 awg to my braided CAT 5, which has a combined 9 awg. So I’m not sure if it was the biwiring or all the other differences that improved the sound.

Also, any other ideas for superb sounding DIY SCs are welcome.

Danke!

@williewonka out of curiosity, do you keep detailed notes on break in behavior? It would make sense, given your blog posts, I’m just curious. I have noticed system anomalies before, after new cables, but chalked it up to my mood.

With regards to my cable details:
Signal - 1x12awg 1x14 awg kinky ’helix’ in opposite directions, both are silver plated copper in ptfe from take five audio.
Neutral - 2x12awg silver plated copper in ptfe inner helix, 2x14 awg silver plated copper in ptfe outer counter rotating helix

It seemed to work better with the thinner neutral wire on the outside since, once I created the helix with the fiberglass rod, I had to wrap it by hand around the inner helix, one twist at a time. The thinner wire was easier to manipulate and even out. That truly was the most difficult part: getting the outer helix evenly spaced. Using teflon insulated wire definitely helped, since the inner and outer helix are able to slide a bit more easily over one another. Now that they’re built, though, everything is solid.

And feel free to use my photos. If you want more, just ask. Also, I couldn’t get all 4 neutrals at the amp end into the BFAs, so I put a few strands between the outside of the BFA but inside the copper crimp sleeves I use. I crimped these as well. I think solder looks better, but I feel like the crimp connections are sturdier. But that’s just my preference..

RE: Audition notes - at first I tended to write everything in my blog as I heard them, but now I just make lists of things that I hear and at  how many hours. Then I flesh it out with details

It took me about 4-5 reviews to get a style worked out, but the first reviews went through a lot of "wordsmithing" based on feedback made by Keith Louie Eichman once he read them.

After so many reviews in a relatively short amount of time you also develop an ear for it. I have about 50 classical tracks and 55 more modern tracks that I am now extremely familiar with, so when I think I hear something I'll go to a specific track to verift an improvement (or otherwise'
e.g.
Is this Love - bob marley
- the image is huge in all directions with lots of space around musicians
Norah Jones - Not too Late
- very little in the way of reverb voice treatment so it's like a personal concert
Higher Love - Stevie Windwood
- superb dynamics - best drums I've heard
Peter Gabriel - So
- superb textures in the bass line
Classical tracks (live recordings)
- I use these to establish how well the image is reproduced

The photos you have will be perfect for what I have in mind

Thanks for the wire details - perfect

I'll post a link here once I get it on my site

BTW - I would like to refer to you on my site as - Audiogon member Toddverrone - it maintains your anonymity, but allow people to contact you via Audiogon should they wish to verify what has been typed

- unless you prefer to remain anonymous ???

I'd also like to "quote" a couple of sentences from your posts here pertaining to your observations if that's OK?
e.g. 
So far, they did superb! The same black background as the single helix with cat 5, but more clarity from top to bottom. There's not more bass, it's just a bit tighter and clean. The mids and highs have greater clarity and come further out from the background, with a better separation of sounds.

RE: your Interconnect
- what is the white stuff under the neutral - some sort of tube?
- what wire did you used for signal and neutral

I think I'll update that page as well :-)

Cheers
steve - use whatever you like, as long as you don't misrepresent me, which i'm 99.99% sure you won't.. feel free to correct bad grammar ("..they did superb!"  i swear i graduated college!).  i'm fine with audiogon member toddverrone.  though that doesn't protect my anonymity very well.. take a wild guess what my name is. ha!

ICs -

the white tube is a foamed teflon flexible tube that i ran the signal through. it's pretty amazing.  it doesn't kink at all.  it's called hyperflex tubing from vh audio

this has been great fun, i'm very happy with both my ICs and SCs.  thanks so much for rolling up your sleeves and getting dirty with me!  your helix design is quite the accomplishment.  thank you for sharing your knowledge.
Ive been through evey thing from
Weilding wire  to the Lowe's thay said was a big hit to. Cat.  All that
Money down the drain.  Buy the
Best wire you can afford. With
Same interconnects.  Listen to the difference
