Digital coax cables

I have been looking to upgrade my digital cable as well, I have a BJC and a Cullen, which work well but I cannot perceive any great difference between the two. I would like to try solid silver and the Take 5 Neotech looks like a good option, I need BNC as well. I have been trolling for a used Kimber D60, which seems to be the gold standard, any comments or comparisons with this cable? 

Also, what are folks thoughts on the 1.5 meter minimum length for digital cables to eliminate signal echo? Absolute requirement or maybe not a real issue?

I did the used coax cable run a few years ago and found large differences. The one that stood out for me was a silnote coax. Wide, spacious and clear, although with a little less bass. Used coax cables are relatively cheap and resellable with no loss. I found it fun trying them out. I also got brand matching rca's, which together let's you learn about each brands house sound.

@gammamike Thanks for the Silnote suggestion, I will check them out.

Take a look at Audio Envy - very affordable and very good

Also look at Zavfino - their TOTL cables are excellent, but a bit $$$

Some companies only offer the 1.5 meter lengths. I've seen photos that show that length measures less distortion, but if it's audible and will actually sound better I don't know. I've tried quite a few myself, all different lengths.The Kimber Illuminati I had long ago was very detailed, overly so for the equipment I owned at the time.IME the $ amount has no bearing on how it will fit into your system and be the right match. If you have some spare ICs stored away give one of those a try.Sometimes they work surprisingly well.Whenever I've auditioned ICs  I always tried one as a digital cable.
