I'm curious if anyone has either first-hand experience with this or thinks that with the specs below it might still be equal to a Scarlett 2i2 using TRS jacks. I'm only seriously interested in ADC. The device is 10 years old at this point, but the predecessor to this, the SE-U55 (limited to 16/44.1), served me well 20 years ago, and the feature set was a lot of fun. I realized today you can order used models of the newer one from Japan for around $100, and might do it just for the fun of it even if it isn't a credible ADC by today's standards. But I would guess it still is. If you have a guess or a better-informed opinion, I'm happy to hear it.

Some of the below may not make sense as it was translated. The manual is here:
