Andrew, it was what was subtracted by adding Ethernet that made the difference in my opinion.
No more reliance on Mac Mini and all the tweaks/upgrades.
No more reliance on JRiver or other music software packages to play music.
No more reliance on USB converters or USB in general (which I never really embraced).
No more computer next to my system.
That's where my head is at. I went with the Zardoz French WIFi front end in 2007 for similar reasons (extrication from computer) and preferred it to my Granite Audio 657 CDP at the time. I just moved on for the sake of newer format streaming. I am considering the Auralic Aries but time will tell.
I am still interested in trying the Lampizator transport with my Lessloss DAC for comparative purposes because I am told the wifi is superior to wired Ethernet. Not sure I buy that statement completely though as Resolution Audio states the opposite.
I have heard contradictory info as well. Dan at dbsystems (maker of Zardoz/LaRosita and a computer engineer) said wireless was better than the Ethernet port on his units. I had a friend who tested this and could not hear much of a difference. According to Steve Nugent, wireless/ethernet is supposedly a superior interface in terns of jitter:

I have always suspicions about cheesewhiz Ehternet cables and jitter but I don't honestly know. The Lampi transport into the Lessloss would be intriguing. I would go that route if the Lampi piece could handle more formats.
As you know, Mr. Lessloss has his contrarian angle on all this, and I very much respect his thoughts. This is his new gizmo:

It looks stunning, but again, there are logistical issues with the size of SD cards and the burgeoning world of DSD/DXD, etc.
