If I understand, you’re using your computer as the source? (Pardon my ignorance if that’s obvious; I didn’t know computers could play SACDs).
If so, yes I’d agree that a standard USB pro audio interface will suffice, especially with those speakers. I’m using a TASCAM US-122L for my computer system with Swans M200 speakers, which are probably about par with yours, and have no complaints.
As far as which ones are popular, that probably won’t be of any relevance to you. Most people who get pro audio interfaces do so for amateur recording, use with room measurement platforms like Room EQ Wizard, etc. IOW, reasons other than audiophile listening.
