Well I have to say I am quite taken back by musings such as well its just copper mate
If people truly believe that all copper is the same then form a cue at Bunning's LOL.
I see no one took me up on the CAT5 interconnects, I wonder why. If I were checking out capacitors (getting back on subject) and hooked them up with ~200mm of run of the mill copper I would have to kick myself in the backside and would expect some censure from other more enlightened one's, but there were a lot of ships spoilt for a happenth of tar!
Japense copper is amongst the best of the large crystal type, you will notice a considerable ease and lack of harshness / glare compared to the run of the mill stuff. The continuous casting process gets you there. So annealed copper anyone? Drawn copper wire, plated copper wire, flat copper ribbon; each and every example will produce different results so I have to disagree with its just copper wire mate and no one makes low quality. Having been to China I will attest to if they can save half a cent they will.
