Aurender ACS100 as streamer/player

After fiddling around with sending digital files from MacBook to DAC via JRiver, I'm researching dedicated server/streamers in the ~$3K range. I've read many posts here, as well as external reviews, and the Aurender ACS100 seems appealing as a potential one-box solution. Close to it is the Auralic Aries G1.1, since one can use an external drive to rip CDs with error correction. I've heard about Innuos Zenith Mk3 (with CD ripper), but I prefer the remote apps offered by Aurender or Auralic.

Anyway, my main question is the value of using ACS100 as a single source (streaming and playing stored music). Aurender has the following disclaimer/warning:

"ACS100 is a NOT a high performance digital audio transport. It is intended as a companion piece to another Aurender. The ACS100 USB 2.0 port is NOT the same as Aurender's hallmark dedicated filtered and isolated USB 2.0 AUDIO port" (e.g., as found on NT150).

Of course they want you to buy a NT150 as well. Yet after all that, they go on to say:

"However, ACS100 does have a USB 2.0 output. So, one may pair this model up with a high performance DAC for a complete digital front end solution if desired."

The implication is that you may get garbage out from the ACS100 USB 2.0 port, but go ahead if you are so desperate.  What have ACS100 owners actually found when using the unit as their primary digital source, connected directly to a DAC?
