I'm a bit lost.... Like i said i have some wire from norne audio and i want to try another one for the fun and thank to Hakuzen for recommending neotech but i don't understand all the difference between, up-occ, cryo, litz... What is the best for my HD800 because i want to keep the clarity and resolution(i already noticed going from stock to the norne audio wire give me a more precise soundstage)
UP-OCC is one of the four certified OCC methods to make wire. made and patented by neotech (taiwan).
cryo means the material gets frozen (cryogenic treatment) during a stage of the production.
the goal of both is getting lower impurities, better aligned crystal boundaries, so the conductivity is improved in all parts of the conductor, for all frequencies.
litz means the individual strands in each core are individually enameled (shielded). this helps to avoid oxidation.
litz geometry means twisted strands, twisted groups of strands. different levels.
litz shielding and geometry should help to decrease EMI noise and to decrease capacitance between conductors by adding more dielectric isolating layers.
the effect on sound from the three methods is supposed to be:
- deeper, wider, more three dimensional soundstage
- lower noise floor
- improved dynamic range
- more articulate bass reproduction
- smoother, more refined high frequency response
my experience with up-occ wires has convinced me of these effects. others will tell you there are not differences.
i'd go mixing up-occ pure silver with up-occ copper.
neotech silver wire at authorized distributors is expensive. most aren't litz nor cryo, but use pvc or teflon sleeve (the latter adds stiffness, but has better dielectric properties). copper is also more expensive than other copper wires.
oem up-occ wires are more affordable, most of them are cryo and litz, and use PE (polyethylene) sleeve. but you can't be sure they are made by neotech. my experience with these oem up-occ wires is very good, so i don't mind if neotech made them. to me, they are up-occ, notable difference with other wires i've tried (OCC / single crystal included).
in the case you want to try oem up-occ wires, i recommend AgAu (silver 99% gold 1% alloy) for silver. for copper, cryo copper litz would be my preferred, but you need to remove litz from the wire between soldering on contacts (DIY), and this can be a bit annoying, so you could go for cryo copper no litz as well.
