First of all, I am a huge Aurender fan. I own two and have auditioned others. They only make streamers… some of the best in the world.
I recommend one… just not that one. The ACS is a specialty box. It was made as an add on box for folks that already had an Aurender streamer who wanted to rip stuff… a legacy box from the not so distant past. I think you would do much better with a main stream… N200 for instance. You can always rip CDs somewhere else. For the future you should have flexibility in connection type and you will get top notch sound quality. No use spending money on non-essential functions.
Once you get your streaming service (Qobuz… is best) quality up to file streaming you are likely to find no reason to rip and store any more. So looking to the future, I would invest as little as possible in ripping and storage. I have thousands of ripped files on my Aurender N100 and W20SE that I never listen to. I have been giving away my CDs.
