Gilman, I have the 918's and demo'ed a few cables over the past year. The best were the new Synergistic Research Accelerators speaker cables. The Cable Company will loan them to you to try.
I could not believe how these new cables transformed my system. I finally have that WOW factor I've been looking for since I bought the 918's. The bass is very tight and controlled.
Also, I have paired the 918's with a Rel Britannia B3 sub and now I have perfect full range music. I too thought the 928's would be better but they still would not go as low as adding a sub. Good Luck!
