I have Silver in my second system that works well with Burson DAC. My main system is analogue only and there I have two pairs of Wywires Diamond interconnects. Great cables. I used to have Platinum interconnects and Purist Audio Neptune, upgraded to used Diamonds at incredible (to me) cost and have no regrets whatsoever. Still have the Neptune in the second system.
I am in fact thinking of upgrading the Silver USB to the Platinum
