I have Silnote Anniversary II Master Reference speaker cables and various levels of their interconnect cables, and find them to be very musical and dynamic. I also have Morrow subwoofer cables and couldn't tell much difference/ improvement from their level 5 to the SVS cables they replaced. Both are well made. Silnote has a range of offerings to suit your budget, as does Morrow, but Morrow's price wobbles dramatically depending on their sale of the month. That's a good thing when you're buying, bad if you want to sell them.
I upgraded from Cardas Clear Sky speaker and IC cables and was very happy with the Silnotes ... until I got Audience Front Row cables. The Audience are MUCH more expensive and do sound better, but not night and day better. Why the change? To see what higher end/ more expensive would bring to my table. It proved to me what I felt when I pulled the trigger and bought them: Silnote is a great value cable, but if you want to spend more, there is a great big world of expensive (and good) cables to choose from, and the law of diminishing returns holds true here.
I coincidentally just put the speaker cables on USAM, and have some of their IC's I could part with if you have any interest (sorry for the shameless pitch).
