@spook76 As a current owner of the Shure SE535, I too have wondered what sort of difference aftermarket cables can bring to the already balanced and lush sound signature.
I then purchased the furutech aftermarket cable from eBay and noticed - after A/Bing with the stock cable - that it increases the brightness and sparkle of the SE535.
Did you notice any mild or significant difference between your stock cable and the pure OCC silver aftermarket cable that you purchased?
I do not want to spark a debate about cables but in my humble opinion the pure silver OCC cable made a material difference. Is it night and day, of course not but the clarity from top to bottom was tightened and the detail is noticeably improved. Some say pure silver brightens the sonic signature, I feel it does not brighten the sound but increases the detail which some as interpret as added brightness. What truly amazed me was the 535 had a great deal more depth that proper cables can bring out.
The one caution I make is that with the improved clarity you definitely need a minimum of 320 bit rate music and the best quality recordings as that makes the biggest difference. Is it worth the $200 for pure silver cables, that depends on your budget but I could not be happier with mine. Another thing I caution you on is if you use an amplifier with your portable rig you will notice the lack of transparency in an low end amp with silver. If you want to discuss it further feel free to send me a private message.
