Digital coax cables

I had the AZ MC2 and it's a pretty good digital cable.  My transport, a Bel Canto  CDT 3, uses a bnc connection so I shopped around for a cable with bnc on one end and rca on the other and found, built by Take 5 Audio of Canada, a Neotech NEVD 2001 with an Xhadow rca and an Oyaide bnc connector used for under $200.  Given the quality of the plugs alone, you'd expect the Neotech cable to sound better and it does, to me.  I hear a bit more subtle inner detail with the Neotech cable but the main difference is a more organic quality to the sound.  The AZ cable sounds a bit mechanical in comparison.  On some material, there can be a slight upper-midrange brightness on my speakers which I do hear with the AZ cable and is absent with the Neotech.  You might check Take 5 Audio's site for more info and the US to Canadian$$$  transfer rate greatly benefits us in the states.  Also, these cables come up on the used market fairly often so check hifishark.com.  But soix is right about re-selling the AZ cables. If you try them and don't find them to your liking or worth the money they will be easy to move.

@boxcarman for your reference, a month ago just for grins I had a 5yr old AQ Cinnamon Digi Coax sitting here, and swapped it back in play to compare to my other Analysis Plus Digital Crystal and my Cardas Digital Clear Digital coax.

It was a fun and quick test to remember and ask myself once again, is it more than just 0s/1s, or possibly something more going on here. It was a surprising test. I was not expecting to hear that much of a difference.

Well the AP and Cardas were close to each other. After an hour back with the AQ Cinnamon, I could not wait to get it out of the system and go back to one of the others. Yep, realizing again, yes, there is a bit more going on here. Was not expecting to hear that much of a difference, and sure enough, proved it to be a weak link for whatever reason, don’t care to figure out how or why, it just did not sound nearly as good, fwiw. Out it came, Cardas went back in place, done. :) 

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.
