Why would you expect any change in use?
Hi 
âŚ
Do you really mean that you have never heard the effect of a properly executed burn-in.?
That is correct, though much of my kit over my hifi career has been purchased secondhand or ex-dem. (The only new items Iâve bought in the last 30 years have been one CD player and two DACs - and I have not noticed any change with them.)
Aside from that, the fact human ears are not constant reference devices, and our hearing changes frequently due to physiological effects (I mean short term not age-related hearing loss), and of course our ears adjusting to the sound of a new device, and Iâm not sure I could conclude that any perceived change is due to burn in unless I could have direct comparison of brand new against used (but not used so long that components will have deteriorated).
In this case, I am curious as to why and how would a computer dealing only with digital data, and in the case of a specialist one like the Innuos minimising RF noise superimposed on its output, burn in?

On many things but not on my zenith at all
Hi 
âŚ
This has been covered in miles of text before,.so itâs best to do a forum search for further information on this.
In the last two years I have performed burn-in on four new head-amps,.and also on a number of cables.
And in a few days I will get a new head-amp,.and also a new Innuos Zen mk3 on which burn-in will be performed on.
I always write protocols during my burn-in periods,.then I see if the results are repeatable, which they proved to be.
If you only have practical experience with this,.have slept well and perform this under controlled conditions, then there is no problem in detecting differences during a burn-in process.
May also take the opportunity to wish everyone here a Merry Christmas.
Hi âŚ
It remains to be seen,.I get a new Innuos home in a few days, so it will be exciting to explore.
BUT,.it is Dr. Sean Jacobs who has designed the powersupplyâs in Innuos products, and he himself says that the powersupply needs a few weeks to âstart singingâ.
Although if one of Dr.Sean Jacobâs standalone powersupplyâs is used,.but has been unused for a few weeksâŚ
SO,.they need up to a week to âstart singing againâ.
No answer to my question on leaving the lan cable in - and burn in discussion that I expected 
So for after 10 days I would say there is really minor change - even when unplugging the demo unit and plugging in the new one I did not recognize any immediate noticeable differences.
With PN it was different.
But lan plugging again - can I let it connected when Innuos is acting as player in a DAC - which is plugged in (non connected to an amp) for burn in reasons only
I have more than one system in my house. I can listen to system A in one room and go to another room to listen to system B. When, the next day, system B sounds the same but system A sounds different I can be reasonably sure the effect is not due to a change in my hearing overnight.
I share your curiosity as to why it happens, but my scepticism has diminished sharply over the past few months as I have heard changes in one piece of kit after another as they have come in and out of my systems. This included swapping out a well-used NPX300 for a brand new one straight out of the box.
As it happens, I bought my Zenith used and it must be the only box where I did not hear any difference in the sound over time.
Merry Christmas to all of you!
Anyone an idea if I could let the lan cable (lan port) plugged in when DAC is connected and Innuos is playing?
I do

I assume you mean the streamer port (the lab one connnects to your router switch and should always be plugged in). If so I see no reason why not.
I mean the lan port, not the streamer port.
Wait a second ⌠there must be a port plugged it to have access to sense.
And should this be the lan (labelled lan not streamer) port?
The lan one should plug into your router and must be connected at all times. If you want to connect the zen directly to your streamer (ndx nd555 etc) you can use the streamer port for that

Thanks - all running fine - running fine in. My dealer lend me a nuprime Dac 9 and I connected it via an old computer USB cable - for running in only all is fine 
I was a little blocked There must always be a lan connection - otherwise no network and no use of sense app
