Just finished updating my 272 to v4.6 successfully (whew!), and wonder if it is really necessary to do a factory reset. I'd rather not have to re-do all my settings. The unit seems to be working fine & sounds great without that last step. Any thoughts? PS - My thanks to Naim and all the Beta testers.
I did factory reset on my NDS,I didn’t loose anything,even my favorites radio stations I see as they were before,is this the way it suppose to be,or maybe I didn’t clear anything and have to do reset again?

It begs the question - are you sure you actually did a reset, did you press the tool (wrench) remote button & get the NDS display >Factory Settings>Reset All Settings & then did you get the on screen warning asking are you sure & if so to press Play button ??? What other settings did it change ??
I'm not sure about the need for a reset after a quite a few beta f/w updates over the years with no resets. However last weekend I did a reset just to test it & see if it did change something. This lost all my iRadio presets & is how I would expect it to be. However some other random iRadio presets got loaded, one was Radio Paradise but not the 320kb/s Naim selection version that I had preset, plus 2 other stations I have never seen before.
Yes I reset my Unitilite pursuant to sorting out where the Tidal option had gone after the 4.6 update and I had the same random iradio stations loaded.

I didn't do a 'Factory Reset' on my 272 - it was fine, with notable increased SQ.
Then I did a 'Factory Reset' on my 272 - it was still fine, and still with the same notable increased SQ.
It seems as though the NDS may have a particular specific reason for benefiting from a factory reset (and, as it does good to some and no harm to others, that would be enough justification for including it in the instructions).
I've reset my NDS to Factory settings (why not?)
If you do this then you will need to check the following settings:
Front display time off (mine changed from 10 secs to default 2 mins)
Imputs enabled. The reset enables all imputs e.g. all digital inputs/spotify/tidal/usb/ipod/iRadio/UpnP and multiroom whereas I usually only have UPnP and iRadio enabled.
Systems automation - all devices disabled so had to re-enable Preamp and change Preamp Streamer input from the default AV input to CD.
(also posted in the parallel 4.6 firmware thread)
As I can’t listen seriously for a few days after 4.6ing the 272 I thought I might just do the factory reset as I’ve a very simply configured set-up. Everything ‘off’ except UPNP, Tidal & iRadio.
I seem to recall Tidal being a bit of a faff to set-up initially - Would this still be the case after the reset? Also, I presume UPNP is simply found automatically by the 272?
Thanks,

Apart from remembering your personal settings, if it's simple as you say, go for it. It shows a Find Rooms icon & then does that automatically, UPnP does not need to be reset, you will lose any iRadio presets, but no big deal to reset them.
Done with no issues cheers MIKE-B.

I must have done ten firmware updates in my two and a half years with the 272 and have never once done a factory reset. With all this talk of doing it I was feeling rather inadequate so have now done it. It seems that the front panel menu is shorter than before, but at least I know that everything is ‘as it should be’.

What interests me is that the last stage of the process under control of the updater programme is described as "resetting your streamer" and you get the same on screen messages on the streamer as if you do a factory reset using the remote, resetting network connections, resetting streamer settings etc but of course as we know it doesn't reset everything. So what is it doing at that stage and why is a factory reset on top of that advised? I think we should be told!

I think we were told at one point - the update resets some things but not everything. It’s nice sometimes to know exactly what is going on, even though it doesn’t really matter.

I’d like to know exactly what it’s going to do, but I also feel like with premium product like Naim, one should not have to know every detail for the sake of self-preservation. The fact that we need to just to keep it functioning properly spells problems.
It simply replaces all the user configuration data with the defaults set at the factory; i.e. the unit then behaves in the same way as a new unit with that firmware.
It's not actually necessary "just to keep it functioning properly", but it may be necessary to enter the new configuration data that are needed by new functions that may be added by the new firmware. Since these new functions didn't exist in the previous firmware their configuration data items just won't be there in the previous set-up.
Naim chose to allow users to keep existing settings when updating firmware if they wish, so they don't overwrite all the user data on a firmware upgrade - they leave the choice up to the user, but they recommend doing it as that will ensure a 'clean start' again.
All this is standard practice.
I’m waiting for someone to suggest a factory reset is best done before loading the new firmware. 
I guess we will have the words of wisdom on needed or not someday soon from Naim
I have a mobile and tablet type mindset to factory reset and even apps sometimes, the advice always being installing over the old installation may leave dare I say gremlins.
Plus on the dire Naim app sure Naim advised the same so why not for the firmware.
I doubt it makes any sonic difference more the gremlins left over not giving a clean install.

Can you think of a product that requires resetting to factory setting after a firmware update? I venture to say backward compatibility is standard practice for many companies and products. Having design principle where resetting to factory setting may be necessary to allow new function in new firmware to work is not the best. It means rollback is not possible. It just makes life easier for developer. It just allows for poorer, non defensive coding and weak configuration design and management.
What gets zapped from the factory reset? Do I need to record my saved radio stations? Why would SQ change from multi room integration and bug fixes? I don't have any other Naim streamers other than the NDX and it feeds a NDAC.
Just taking one example, it's not at all uncommon in the automotive industry - if a change to tuning is involved in a software update (e.g. a change to the mapping) the engine management data are very often reset and the engine is then allowed to re-tune itself over the next 200 - 1000km. This even happened when the gearbox software of my car was updated - it took a few hundred miles for it to re-learn my driving preferences.
Rollback is perfectly possible, just roll back and factory reset again! Actually, as configuration management often specifies that you should just add additional config items to the end of the existing config data, in that case the factory reset is often not required.
The problem with defensive coding in systems like the Naim streamers is that the additional code causes additional switching spikes to be generated by the processor(s). This 'noise' inevitable gets electrically coupled to other parts of the system through the power supply and ground planes, with the commensurate potential for degraded sound quality.

Basically it zaps anything you have changed from stnd to as it was when it left the factory. Your iRadio presets will get zapped, so a note of these would be advisable if you have a lot of them. Good idea to make a note of your input & output settings for connecting nDAC.
