I have owned an A-10 for a year now. As a stand alone its sounds very good. I have it mated with a Micro Zotl 2.0s and have just upgraded my cables to Audience Au24SX. Mated with Odyssey Kismet Monos and Magico S3 speakers it sounds pretty damn good. It replaced a Aurender N100>Oppo 105 with full Modwright tube mods and it absolutely kills it.
My friend brought over his Yggy and we A-B and there was not a preference. Ran the Usb out to the yggy so just had to flip the input switch on the preamp and levels were matched.
The Absolute sound review was the first I saw that was not absolutely excited about it.
Here are a few reviews.

So you can see a lot of positive press.
Full blown MQA is a nice bonus. I replaced the Oppo 105 with a Oppo 103 and use that as a digital preamp which runs to the digital in
of the Aurender. You Tube, Cable, etc all sound outstanding in a 2 channel system.
I think it is a great piece. There was a unit for 4800 that sold in a few days here so looks like it is going to hold its value.
I think the street price is under 5K so it pays to shop.
Good luck with your decision
