Any opinions on Morrow USB cable and SP5 Speaker cables?

I’m very pleased with my SP5 cables. These replaced Acoustic  Zen Sartoris—which also sounded very very good. But the Morrows sounded better, more transparent, more detailed. The Morrows are bi-wired and the AZs were not, so that can also be a factor.  (Bel Canto ref500m monoblocks driving Dali Mentor 6 speakers.) The other thing I really like about the Morrow is that they are so flexible and easy to install. Nice people to deal with as well. 

Many thanks for the input tomaswv. 

No experience with the USB but I use the SP-7 speaker cable and have been pleased with it.

I have used Morrow SP-2, SP-4, and now SP-7. They are pretty good. I bi-wire on a couple of different sets of Speakers and find the SP-7 are great for bass. However I've found less expensive Cables that better the SP-7's on mid's/highs.
