Like Daniel I stayed with the second to third-tier Monster cables on just about everything. Out of desperation when I couldn't find the Monster cables I did purchase a few high end Radio Shack cables. I'm not too happy with them but they seem to be doing the job although they are not connected to the major components.

John makes a good point of price although I think you have to average the cost across your system. (How that for rationalization!) For example I found the Toslink cables to be EXPENSIVE but well worth the money! If I was to take all my cables and average the cost I came in about 10% of the cost for the entire system.

I like the Monster cables although I would liked to have had more choices. I found the selections of cables to be very limited in the many audio shops around the DC area.
