Another great review.
If you get the chance, I strongly recommend you try Vertere's D-Fi and the even better DD-Fi USB.....I was slightly shocked at the difference they made.
I can't remember if you saw my review of Vertere cables, so I'll link to it just in case (it's in three parts): http://www.whathifi.com/forum/accessories/an-evening-with-touraj-moghaddam-vertere
IMO. This cable is a must audition for anyone who is in the market for a USB cable, wants to test if they can get an improvement and is prepared to try something different.
