Optimal length(s) of a digital aes/bsu cable


I have an option of a high end cable (0.6m) as a digital interconnect between a Berkeley USB and Reference DAC. I’d rather have a short cable practically speaking as the boxes sit next the one another but I also want to maximize sound quality (of course.)
i have read in agon that I should go with less than 1ft or >1.5m. That was with spdif but what about aes/bsu? Does that have a different dynamic, being balanced and all?
Thanks!

Doesn't matter use the .6 cable short AES3 cables are used in pro studios all the time.
Back when I owned a CAL Delta CD transport and both their Alpha and Sigma DACs; I needed an AES/EBU cable.      Bought a Kimber Orchid in the .5M length, since they were to be parked right beside one another.      I couldn’t believe how bad the combo sounded (with either DAC).      Vaguely remembering something read about digital reflections in transmission lines, I tried the Orchid in a 1.5M length and found Nirvana.           My suggestion would be; audition two lengths of the same cable, for yourself.              https://www.audiosciencereview.com/forum/index.php?threads/technical-article-digital-audio-cable-ref...
yes, to be a bit more specific - 1.25 up to 2 m - so 1.5 m is a safe number

digital reflections can occur (at least in theory) at 1 m length
There’s a lot of good theory on this subject. In practice though, how cable length effects sound quality is difficult to hear. We manufacture cables and have tried various lengths of the same build. For our ENO Digital Cable Cu and Ag, two cables built identically, one at 1M and one at 1.5M sound identical. If you start talking about much longer distances I’m sure things change.
Thanks for the input fellas - all very helpful! BTW - the link from rodman9x is an excellent piece.
