Like @jond, I have an Aries G1 and am quite pleased with it. It's solidly built and easy to use, without the fiddling of Pi-based streamers. I also appreciate the display, which (e.g.) shows the IP address upon boot up -- very useful when setting up the Web-based configuration. Also a nice feature is the ability to hook up a CD drive, thumb drive, or external hard drive via USB.

Whether you would notice a sonic difference from the Element S is another question. Matrix makes very good gear also, in my experience.

I would check with Auralic that the USB output is compatible with your DAC, as I've heard a few horror stories of damage to the Aries G1 from a few DACs. That may have been resolved in the G1.1 model, though.

@jond  Email me at support@audiogon.com with the URL you are trying to use and I'll answer you back on Monday. Thanks. :)   

Thank you mike_in_nc for the heads up on the USB output.  

That sounds like pure nonsense. I've used two G1's with over a dozen different DAC's in the last five years and never had or heard of a compatibility issue. Typical audio forum BS from users who can't read a manual. 

The only compatibility issues you may face is if the dac usb driver isn’t compatible with linux. Check with Lampizator for this. 
I had the G1 it was decent but I tried Lumin U1 Mini and preferred it over the G1 on sound quality alone. The UI on the Auralic is light years ahead of the Lumin though. The screen on the Auralic didn’t do much for me so I ended up shutting it off. Also had issues with network several times and required me to reboot the G1. Lumin is stable. I tried both streamers with Roon. The Auralic sounds better using its lightning DS software. Lumin sounds about the same with or without Roon. May be they addressed the software issues that caused network connectivity problems by now…don’t know. It’s been a couple of years without Aurelic in my system.
