Some vintage amps have significant limitation gauge wise, and USB is standardised to 24AWG or 28AWG, so going for pure copper is worth the small premium IMO.andyjm said:While I normally agree with Vlad, there is nothing intrinsically wrong with CCA. Sure, if you have two cables the same thickness, then copper wins over aluminium. Use a thicker aluminium cable.Vladimir said:By default thicker is better in all cable applications, including USB.
What's more important is to have pure copper, not CCA (copper clad aluminium). A smaller gauge pure copper wire will outperform a thicker CCA one.
Equally if you have two cables the same weight, then aluminium wins over copper. Where weight really matters (overhead grid cables for example) aluminium cables with a steel core for strength are used.
How can you ignore the countless hours of Research & Development invested in making audio cables? Men in lab coats have mouths to feed too you know (mostly cats).Rethep said:I just use cheap plain copper wire. But then again i also use a cheap DAC .
I don't think there is any other reason to use expensive cables, then to fill the pockets of them who make 'em.
INDEED ....CnoEvil said:Some would argue, that it helps to be thicker, when it comes to believing anything but cheap interconnects make much difference. *unknw*
