I can’t afford unobtanium but I am using all silver upocc Neotech I bought in off the reel in one system and a signal loom of all Wireworld platinum eclipse upocc silver in the other. In the Neotech loom I now have a 12 metre upocc silver Neotech run as ICs and also with the heavier gauge silver Nemos used as hook up cable for my horns. As a cable I find these to have an extraordinarily open, immediate quality that seems to get out of the way and allow through and easily follow the flow of sound and music seemingly unimpeded. The cables bring through moments of realness in nature that match with the very immediate nature (in a system approach) with both horns and SET.
Going to a 12 metre run of Neotech upocc silver in single ended ICs seems to have very little if any sense of loss when used in the longer run and I had swapped these in to replace a 1.5 metre ICs run. I thought there’d be some loss but the low capacitance geometry seemed to really not be challenged at all by the longer distance. I’ve trialled using the upocc silver cores in the Nemos 1080 run as 14 awg and also as biwire run at 11 awg for speaker. That characteristic quicksilver upocc silver nature comes through in each usage.
The rectangular geometry in the Nemos is a bit trickier to work with in bare ending and terminating and kindly a mate who has a lot of experience in making up cables did it for me and also went with WBT silver connectors. The Neotech cable itself is beautifully constructed. I thought about using the Neotech copper Nemos for the open baffle subs I’m working on but have enough of the upocc silver Nemos here to wire them with that so may stay all upocc silver all the way through.
The Neotech upocc silver easily compares similarly in nature and the sense of transparency to the Wireworld platinum eclipse upocc silver cables that I have… and there would reasonably be correlations since neotech provides the core wire used in Wireworld platinum and also provides it to quite a few other companies.
In some ways I think they might even just eclipse (apologies in advance) the Wireworlds… but very similar in that inherent sense of extraordinary ease and open naturalness that top end upocc silver can have when used throughout as the signal cables in a system.
If you build the balance of your system around your particular choice of good metals I’ve found it’s possible to get great balance with either silver or copper. The low capacitance Neotech upocc copper would be the way I’d very likely now trial if I was going with copper. The best implementations of both metals can sound very natural and true, but the sense of immediacy that can bring through moments of realness is a special ingredient that I’ve found that can more essentially come through with upocc silver. With regards to top flight store bought unobtanium I leave that to others far better equipped to call
