Funny this come up considering I'm currently evaluating a number of digital cables. I make my own usually but I thought I should try the better "boutique" cables to benchmark that I'm doing it right.

Best digital tested in my system:
Wireworld Gold Starlight 6

Second best:
Meridian black cables with soldered WBT Nextgen RCA's

then there is alot of different cables that might not be much better than Meridian blue soldered cables.

I do really enjoy the Wireworld Gold Starlight 6 on mains L/R out from the HD621. There is never any strain, just pure dynamics and microdynamics better than the old M blues. I also tried the lesser Wireworld coax cables but I found them not as big step up from my old cables and therefore is not worth the $$ in my system.
