Star-quad means two twisted pair wires that are twisted to have even more common mode noise rejection than a single twisted pair. But let's stick with single twisted pair only. Even Hypex recommends this for Fusionamp speaker cables in its manual. Logic dictates that it would be important on the input cables as well, and since the transmission is truly balanced here and this signal will be greatly amplified, it can be even more important than at speaker level. Yes, Fusionamps comes with those blamed ribbon input cables and they are noisy too (relatively speaking).
Speaker wires are twisted to reduce interference transmission due to switching frequency residual, not for reducing noise pick up.
Yes, similar to the signal input cables inside the enclosure, close to a switching amp and/or power supply or other cables, it's a rather noisy environment.
Conjecture.
What benefit do you think cryo brings? In cables, normal electrical-grade copper is fine, the topology matters more - there is a reason that both long-distance telephone wires and high-speed digital connections use twisted wire - and having a differential/balanced input makes the most difference.Just fyi, I know about braiding to reduce noise pick up in the interconnect domain, with regards to capacitance also.

Category: Cables So I decide to once again try and finally answer the questions of what is the best cable – for my system at least. I’ve spent 20 years...forum.audiogon.com
I purchased some rolls of cryo OCC solid copper wire, enamel coated shortly before he (Dennis) retired, when DIY instructions were available.
I'm not suggesting cryo brings any benefit, just that at that time I was aware of benefits of cryo treatment as used in some racing car engine blocks, to 'tighten' and thus strengthen the metal material, something to do with crystal structure, so I believe.
Sure, if you have wires that get shaken around a lot.
I was thinking that conductivity could theoretically be supported by material strength, ie that it is more 'homogenised'.
There really isn't any correlation.

In one of the least physically demanding applications, home audio, there can't be a practical benefit.
I mean it's a funny thought indeed. Materiel strength of copper wire being relevant for conductivity, in audio... I want to have whoever came up with that was smoking.What some theorise to satisfy their beliefs.
This industry is full of it, take any product that is technically good enough, sprinkle some 'fairy dust' with some fancy marketing bs and you have a usp.I mean it's a funny thought indeed. Materiel strength of copper wire being relevant for conductivity, in audio... I want to have whoever came up with that was smoking.
It's the 'single crystal' aspect that is the important part, seriously.I mean it's a funny thought indeed. Materiel strength of copper wire being relevant for conductivity, in audio... I want to have whoever came up with that was smoking.
To answer that post's query: no, the grain structure of a cable's copper is not going to affect how "smooth" the signal's "ride" is and alter it in some way we cannot measure, regardless of the usual bad car analogy by someone who doesn't understand the topic.It's the 'single crystal' aspect that is the important part, seriously.
Single-crystal OCC Wire - Can It Make a Difference?
I recently posted up a request for good sources of OCC wire to make some nice DIY cables of all sorts. I'm still waiting on the materials to make the cables, but I was wondering what the community here thinks about the possibility of higher-purity single-crystal wire having better signal...www.diyaudio.com
