Recommended AES/EBU cables under 800 dollars


I am interested in recommendations for the best bang for the buck high end digital XLR cables, new or used. I have tried a few in the $300-400 range and have not been very happy with them. The best I have heard was an Audio Note Sogon. It was $750 used. Wondering what else might be out there.

Thanks for your advice.

I think the HT Photon is a $3500 cable. Hard to see, even used, how that would end up in the sub $800 range, but thank you for the suggestion.
IMHO, it's worth giving the Kimber Select Series a try. You might be able to whip up a pair of KS-116 or possibly even 1126.
