Greetings Dsnuts, once again I have a question. Your impression with the Penon Sphere I think referred to/mentioned a single crystal copper cable really benefited the overall sound of the Sphere's. Once again, I come away impressed with your review/impression and your take of and the value of the Sphere. So, I have decided to order these (also have the L3 on the way) and rather than buying a cable at or near the cost of the iems, what would you recommend for an upgrade from the stock? Also, does the pure copper (single crystal), only increase the clarity of the bass? I was looking at the ISN single crystal ones (@ $48-$58). Is this a sufficient choice or do you have another recommendation from Penon? Thank you again for your help and expertise.
Cheers
