Is it true that a digital cable has to acclimate to your system?

It's 1.5m.
Ted.

thanks for the input.  I am inclined to return it as well.

Thanks much!

Thanks Steve. 

Thanks,  but I have to disagree.  There is definitely a clear improvement.  I was a piano tuner for 15 years and my ears are very senstive to what they are hearing.  I think Steve from Empirical Audio is right.  He said,  "The explanation is nonsense, however shipping any electronic equipment causes static charge to build-up in the dielectrics. It takes about 3 days for this to dissipate. Also, the new connections probably have to adjust at the metal-metal boundaries. It should sound better after 3 days of break-in.
Best,
Ted.

Thanks for the tip on the Blue Jeans cable.  Just checked their web site and I think it's worth buying 1.5m one to do an A/B comparison.  It'll only cost $25 to buy it and I can always use an extra for my little recording studio setup..

Hello Audiogon Friends - 

I am delighted to say that the Kimber Orchid AES/EBU cable I bought is sounding better and better.  So there must be such a thing as "break-in" for a digital cable,  even if it is a used cable.
At first,  I noticed a very grainy treble coming from my 802D's.  But now,  the soundstage is wider and deeper,  and I am really beginning to enjoy it now.
Thanks for all of your input.
Sincerely,
Ted.
