anewmission Posted July 2, 2021 Posted July 2, 2021 Hi there, looking for mono crystal or single crystal copper cable by the metre. I have been reading into this and could be a cheaper way of upgrading all the wiring in my system rather than using silver. Power cables and speaker cables would be first and then interconnects. Possible amp upgrades?
muon* Posted July 2, 2021 Posted July 2, 2021 (edited) Neotech have a UP-OCC wire. You could ask Geoff at Aurealis Audio, otherwise places like partsconnexion in Canada stock it. https://www.aurealisaudio.com.au/contact/ https://www.partsconnexion.com/wire-cable-non-terminated.html https://wp.neotechcable.com/ Edited July 2, 2021 by muon*

Didn't realize. Maybe it's just the furutech stuff. I am really interested in the nordost style speaker wire. There are some Chinese companies selling the flat occ copper with silver plated unterminated. Very interesting. Still not cheap. I'd be looking at about $350 for the bare wire

And the nordost style for the rears. 1
muon* Posted July 5, 2021 Posted July 5, 2021 @anewmission I'd be careful comparing prices to random Chinese stuff, as there are likely big differences in material qualities. Might not even be real up-occ.

I'm wondering if I order more of that, will it be good for power cables? That's just pure copper but will I notice a bigger difference in my pocket or my ears at the end of the day

On power, make sure whatever you use is rated correctly, construction and dielectric strength ect'. With power I'd be looking at made for purpose stuff, but that just me. I was considering power cables and was looking at this for those. https://www.partsconnexion.com/DHLABS-75520.html Edited July 5, 2021 by muon*

My never ending search for high quality male iec terminations is still on search... Forever I remember Trevor mentioning years ago on here that iec is a pretty terrible connection and there is a better one that could save alot of money on high quality furutech or whatever iec connectors.
denimhunter Posted July 5, 2021 Posted July 5, 2021 47 Labs from Japan have 0.47 and 0.65mm sold core crystal cables with air dialectic. Very simple and excellent as both speaker cables (0.65) and rca of thinner gauge with their non metal proprietary rca connectors-no solder. 1

Also it says it's shielded ... but the pic shown when you click on the link doesn't really show there's a shield? (Just a drain wire.) You can buy heavy-duty stranded flex from Oz electrical wholesalers (I bought 30m from Lawrence & Hanson). Andy
anewmission Posted July 5, 2021 Author Posted July 5, 2021 Anyone know much about the neutrik powercon? It's a locking power (speakon) . It wouldn't be too hard to chance some of my iec to that. The mogami w3081 is shielded but has 4 , 11 or 12 guage wires.

Look closer, there is a foil and a braid, the strands you see as a drain wire I think are the teased out braiding.

The voltage rating and temperature rating for the insulation would be the most problematic. I just have had a quick look on the internet and can not find a spec sheet for any DH labs power cables so can't comment on their ratings If anyone can find the specifications, I would be very much interested

So it's more about application that defines the two. And It's obvious that I was not talking about conductive materials in the context of my post. Edited July 5, 2021 by muon* typo

Hytram Posted July 5, 2021 Posted July 5, 2021 I would be supprised a manufacturer like DH Labs would make a power cable that wouldn't be compliant with most world markets.. But I have seen weirder things. And specs are specs and Australian Standards are a biatch

Picture shows foil shielding that has been cut the same spot as the outer insulation As far as the neutrik powercon stuff I found this. Does anyone think it's worthwhile or am I better just spending lots on iec cables? The NAC3MX-W is a 2 + PE locking male Cable Connector with screw contact termination, polyamide (PA 6 30% GR) shell, 2µm Ag-plated CuNi1Si0.2 contact, polyamide (PA 6.6 30% GR) inserts, ZuAl4Cu1 locking element and polyacetal (POM) strain relief, 12AWG wire. The powerCON TRUE1 is a locking waterproof 16A true mains connector. It replaces appliance couplers wherever a very rugged solution in combination with a locking device is needed in order to guarantee a safe power connection. The powerCON TRUE1 is a connector with breaking capacity (CBC), i.e. it can be connected or disconnected under load or live. <=3mR Contact resistance >0.1GR Insulation resistance after damp heat test (IEC 68-2-30) IP65 Protection class >5000 Mating cycles lifetime Easy and reliable locking system Extremely robust and reliable Unique Neutrik cable retention ENEC Certified according to IEC 60320
Hytram Posted July 6, 2021 Posted July 6, 2021 In my anecdotal experience they can better and when I finally get around to building the power part of my system I will be building a power board out of them and using on the male end of the leads. I will not be using them on the female end of the lead or the appliance socket on the units as this will avoid warranties. But saying that, again anecdotally they would be better there too. Just be careful some of the Powercon connector differ with breaking capacity, meaning some can and some can not be connected or disconnected under load or live. **All this work should be carried out by a licensed / qualified person.

I remember Bill finding some when asked to make up some cables recently.

Pretty sure locking iec's just lock the sides in, where as these neutriks look to have covered all areas
