As several of us have posted inadvertently or in response to other queries about new firmware in the incorrect threads, time to start a new more specific one for the products above.
Probably best for Mu-so/Mu-so Qb owners to have a separate one if needed.
Naim released 2.3.1 on March 19th to address HDMI S/PDIF issues:
This ruined my Nova's sound - made it thin, lifeless and unengaging. A couple of others felt the same, others were more positive so fair to say inconsistent experiences. Some found a factory reset helped, others didn't.
I remain puzzled why firmware 2.3.1 was released when we then got 4.6 for older streamers and 2.6.9508 for the new Uniti series (well Nova anyway - I assume Atom/Star are the same) only a fortnight later, though presumably there are good reasons:
I had maybe a 10 day gap between listening to the (to me) awful 2.3.1 (19th March 184.108.40.20664 - app screen grab) and 2.6.9508 (released 4th April), and only did limited before/after listening. They didn't seem too different though perhaps the latest is not as harsh sounding, and while I think 2.6.9508 the app currently shows is a little better, the sound of the Nova overall just seems lacking compared to a few weeks ago before 2.3.1.
It simply doesn't engage me in the way that 2.3 (8574) did before I installed 220.127.116.1164 on 20th March.
Until a few days ago I only played digital audio on the Nova - from WD NAS, via rear USB, Roon from Mac Mini and a lot of Qobuz playback using Chromecast built-in.
Having listened to the 4th April firmware for several days now it is undeniably quite detailed, but just sounds fairly thin and uninvolving comapred to the Nova prior to 2.3.1. Another poster Obsydian sums it up saying it seems to have 'lost its mojo'.
In the last few days I've hooked up my old Linn LP12 via Analogue 1 input and it's a much better experience than lossless SD/HD digital audio from the LAN or streaming apps.
It's not that it sounds bad/distorted or anything like that, just that it no longer seems engaging/involving in teh way it did before.
Some recommendations from others in the Music Room threads turned up some fantastic tracks/artists which really showed what the Nova is capable of - these same tracks now seem rather lacklustre and don't thrill in the same way - many things just seem like background music not engaging audio.
Admittedly all this is highly subjective, but for those of us who feel our devices sound worse it is all the more frustrating due to the apparent inability to revert to older firmware which we were happy with sonically - placebo effect or not, without being able to go back to compare we'll probably remain convinced something has deleteriously affected our device's sound quality.
Please provide your comments based on your experience with the latest updates.
I appreciate there may be some known issues others have I have not mentioned.
