UP-OCC solid core copper for speaker cable

After reading about all these expensive cables and their extravagant claims, I decided to source the same wire that goes into many of them.

I have my monoblocs underneath and therefore close to the speakers. I ordered 8 feet of 14awg UP-OCC wire (with PTFE insulation) online. It is quite springy so I clamped it gently to the bench and cut it into 4 equal lengths. Assembling it into 2 x 24" speaker cables took a few minutes. I kept it running in the same direction, just in case. Be careful to gently slice the insulation and not to scar the copper.

Anyway, the improvement in sound quality was of a high order. Large increases in speed and transparency, more air, better definition of instruments, less coloration, backing voices I never noticed before etc. The improvement in musicality was impressive.

I urge folks to try this before spending lots of money on speaker cables. I don't bother with connectors as I feel they are another item in the way but that's your call. The wire was $6 a foot.

Hey guys - I'm looking at this Neotech stuff, especially factory terminated ICs (NEI-3005). Prices are VERY affordable. Wouldn't mind trying a 2 meter pair between preamp and mono blocks. BUT I think the stuff I'm seeing is stranded and not solid core?? See link. Do they make a terminated solid core- or even individually insulated stranded?, i.e. w/Teflon insulation??. Thanks in advance for your input on this.

Make your own! They are all stranded as the solid core is springy and unwieldy. Apparently the NEI 3002 is very good.

Awesome definition, I too do not like connectors but use them to sell completed cables only. I use multiple solid core UP-OCC copper wires for speakers and crossovers with FEP insulation and have found them to sonically destroy any other stranded cable I have ever used or installed for more than 25 years of speaker building and studio recording installations!

I have had great results with DIY solid core pure silver speaker wire in series with Furutech OCC. I also have several layers of Bybee purifiers in the mix.

Wow, I find it odd that a big improvement in sonics could be had by swapping out 24 inch long speaker cables. I'd suggest the the old DIY pair that noromance was using had developed some issues.

At any rate, I've done the exact same thing, only it was cheaper. Audioquest Type 4, buying the bulk variety for $5/ft not the $6 noromance paid. It's also less difficult to work with by the sound of it. I am using 12 foot lengths, and this is the cable that proved to me that cables do make a difference.

Yes good sonics can be had by not spending much. But you can get more improvements as you go up market. It's a question of priorities and money.
