I really considered the Card Deluxe when I was looking at 24 bit cards. It has many advantages over other cards, great sounding converters, 24/96 capabilities on those converters (the only advantage it had over the Lynx One card), NT drivers, good price.
A couple things made me decide on the Lynx card.
First, I decided that 96KHz, while would be a great thing to have, but, would not be as evident of a quality difference over 48KHz. So I had to remove this feature from my considerations for now. I figured that when I really NEED 96KHz, I will buy an Apogee converter and send it to the AES/EBU input on my Lynx.
The Lynx had midi I/O, and word clock I/O. At the same price, that was the biggest difference. Also, the Lynx as I recall, had more digital I/O features.
What I really wanted in a card was 24/96 converters, midi I/O, AES/EBU I/O, S/PDIF I/O, word clock I/O, NT drivers, under $500.
The Lynx met more of these requirements then the Card Deluxe did.
I am sure that the Card Deluxe is a fine sounding card too. It just didn't address as many of my requirements at the time. The Lynx card wound up costing me slightly less at the time too. Not a very big difference (like $30 or something).
As I recall, it is very hard to find a stereo in card that supports AES/EBU that ALSO has NT drivers. If 95/98 is your game, then your options open up quite a bit.
