First I sought assistance in installing the update. Had all the Mac problems described in the umpteen posts. Unfortunately I missed the advice to use the drivers from the 4.4 install. Naim assistance suggested I obtain a PC (honestly. Whilst attempting to be helpful, I am somewhat underwhelmed at the technical savvy of Naim tech dept.).
4.6 installed from a PC. Sounded, hmmm, not an improvement. A little grating and flat, early CD-like.
Factory Reset. Oh, I did not want to do that. I had tweaked my remote control, and lost the link to the tweaks (anybody who can direct me to the page of alternatives, please). But the sound quality. I did the reset. After a worrying couple of minutes when all the screen showed was "Analogue", I discovered the UQ2 responded to the Android App, but no such luck with the remote control. Another call to Naim: "We don't know the key sequence to reset the remote control, we'll get back to you." I found the post on here with: "Turn off the UQ2. Turn on after 20 seconds and press Aux, i and 5 buttons simultaneously once the logo shows." That worked.
I called Naim and thanked them for their responses and updated them as to how I had actually resolved the issues.
Bottom line:
(1) Naim digital products lack coherent software support. The guy was nice on the phone but the level of competence presented was disconcerting. The support for OSX on this update is woeful.
(2) 4.6 AND the Factory Reset definitely improved sound quality. I prefer the sound now to prior to the update.
(3) UPnP access from the UQ2 is an order of magnitude faster and, finally, bug free. I've not seen other comments on this change. I am using LMS on a Mac Mini (late 2012), wired to the same switcher as the UQ2.
(4) I had no idea, where to post this. There have been so many posts on the 4.6 update.
