Please check Bogdan cables (ICs and speaker)discussions on this forum as well as AudioAsylum.com. The Bogdans are Silver and posses all the positives of using Silver but does not have the associated harshness as other Silver users complain about. Also, if you have a little bit bigger of a budget, the Empirical Audio Holophonic is worth auditioning, one of the best ICs around, bar none. The two cable manufacturers mentioned provides exceptional product, customer support, and value that meets or exceeds their reputation and your expectations. IMO these are two of the best "giant killers" around, at any price.
