I've always been happy with my Signal Cables. I used to use their Silver Resolution phono cable on my Scout until I bought a new phono stage and all of the sudden started getting RFI interference. Swapping that cable out for VPI's phono cable made with Discovery wire solved the problem. At first I felt like I lost some of the punch of the bass, but soon realized that for a very slight loss of bass punch I was getting beautiful midrange. Until 2 days ago I had been using Silver Resolution from my phono pre to my integrated. I switched to Discovery Signature's and have improved even further on that beautiful midrange.
I'd say that that to compare the two, the Signal Cables do the top and bottom really well, but the Discovery bests them in midrange and a bit of a more balanced presentation through all the frequencies. So far, I prefer the new Discovery's, but the Signal Cables are a terrific product and very high quality. Give Signal a try. They're always available used around here at good prices.
BTW, I put my Signal Silver Resolution interconnect on my CDP, and it easily bested the Cardas Crosslink I had previously been using.
