Are the Crimson cables as good as they say

"I did not see any Crimson cables used for sale so I would not bother trying them myself because you will take a beating if you do not like them and have to sell."

There is a dealer demo program in place for Crimson Cables. You can try before you buy.

Do you have crimson gear?

I have a pair of 1m balanced Crimson ICs in my system that were purchased here on the 'gon. They are reasonably priced new and a bargain used.
IMO: they are an excellent cable and well worth the money; but, as always, YMMV.
Definitely worth a try though. Currently considering the SCs.

Yes, they are that good. I have one pair balanced IC's between my int. amp and sacd player along with 2 pairs speaker cables for bi-wire setup. One speaker cable was great, but two was wonderful. I bought even though they were a little out of my price range...that good. I was able to try in my system for an extended period free of charge. Contact Creston or Creston Jr., these have to be about the nicest guys in audio, at Austin HIFI in Texas for free in home trial. The cables are so clear. You feel like everything is getting through. More than you thought was possible anywhere near this price range!

I did the Crimson home demo and found that I only liked the speaker cable in my system. I replaced the speaker cable about 10 months ago with DNM and like those better. If possible do the in home demo and make your choice with your own ears in your own system. I agree with Tuffy72561 that the Creston's at Austin Hifi are the men to deal with, they carry both DNM and Crimson.
Good luck....
