Ayre QX-5 Twenty steaming performance

Im not sure this addresses your question.  I run Roon core on a Mac Mini that sends files via ethernet to an Ayre QX-5 Twenty.  In addition to rips and downloads, I stream Qobuz and Tidal.  The audio chain includes Ayre KX-5/VX-5 Twenty preamp/amp driving KEF Ref 1s supplemented by a pair of Velodyne HGS-10s with SMS-1 bass management.  The sound quality is superb.  Files sent to the asynchronous USB port of an Ayre DX-5 DSD sound nearly as good.

I have a QX5 Twenty. The ethernet input is adequate, but I find that a Lumin U1 Mini sounds noticeably better.

I’m skeptical of rossb’s claim, but John Atkinson’s review of the QX-5 Twenty for Stereophile did suggest it’s sound improved when paired with a KX-5 Twenty.  Ayre gear always seems to sound best in a balanced setup, and I've only heard mine with that pairing.

I’m not sure what "claim" you think I’m making. I listen to my QX5 in a balanced set up as well, with an Ayre AX5 Twenty.

To be clear, I am using the Lumin U1 Mini as a streamer into the QX5 and comparing it to the QX5’s own internal streamer. The U1 mini is a noticeably better streamer, but unless you do the direct comparison, the internal streaming capability sounds perfectly fine.

This is consistent with some comments by the late Charley Hansen on the Computer Audiophile thread on the QX5. Hansen had said (I am paraphrasing) that the ethernet input of the QX5 was a bit of a compromise and that a good external streamer had the capability of sounding better. It’s worth reading the thread for this and other helpful and interesting comments from Hansen.

I must of missed the thread on CA where Charlie Hansen said the QX 5 ethernet is a bit of a compromise, Is your QX 5 connected with ethernet or USB from the U1 mini.

I think it was Michael at Arye who told me over the phone along with several other QX 5 owners ( including myself ) feel the ethernet sounds better then USB.
