If you don't need ultimate do you need HD Native/DigiLink? Do you want to put up with using an external Thunderbolt chassis? (or trying to buy a HD Native Thunderbolt box?). Including dealing with problems Avid is apparently having with supporting cards these on Apple Silicon based Macs. If you don't *need* this (e.g. video sync) you might be better off selling what you have now and buying a CoreAudio interface. RME is my personal goto interface vendor but there are lots of great companies out there, and for most users it's benefits not disadvantages of moving off DigiLink to third party CoreAudio/ASIO interfaces. Also selling DigiLink stuff now while it still had higher value might be a good idea.
