And Sbooster is not even the best psu you can use with your U1 Mini!

Interested. Which is "best", please.

The consensus on this forum seems to be that Paul Hynes SR7 is one of the very best and practically unobtainable power supply. No doubt a 12V version of it would be great with the U1 Mini.

[FIndingit]

Check this:

I think the U1 Mini needs at least 3A 12V.

Is there any way to prevent the Settings/Music Library window from popping open every time I go back into the Lumin app after X minutes? I don’t know what X minutes are but I’d prefer it not open at all. 
 

 

This is my wish also. The app now and then reverts to the library, whether it exists or not. Would be nice to always stay at the last chosen “source” like Qobuz.

@wklie great news! Latest update works as requested. No more constant popping open of the Music Library window. Thanks 

Really? I have 6.1.16 and nothing has changed, still popping the window. iPhone as well as iPad. 

[FIndingit]

I see. If there is a server available, it will open the “Select a Music Library” window OR show the previously chosen server contents, even if it is offline. If there are no servers AND no server has been selected on previous visits, it will not pop up or revert to library. That’s new.
 

Now we just need the “always stay on last chosen music source”. Please.

Thanks, @One and a half. I will contact Bosch referring to your tip.

 

At the same time I did not have this issue with AES. I guess it is less sensitive (higher voltage?) than USB. But for USB I lost contacts many times per day during my first months with Lumin. But since approx 2 weeks using USB again it has worked with no hick ups. The only changes made is new version 13/13a. Could not USB connections be more or less sensitive against HF noise?

Did you possibly use ISO Regen between Lumin and dac before? I have it between Lumin U1 Mini and Gustard U16. Every time I switch off lights in a certain closet, I lose the connection.

I used to have a Supra cat8 cable with shielded  connectors into U1 Mini from a modded FMC. I removed the metal from the connectors which destroyed the sound. 

[FIndingit]

Surely the fuse’s recommended amperage varies by mains voltage?

Only you can decide these things in your system, I would recommend giving the orange fuse a shot though, as they are returnable fo you do not like what they do.

They are returnable if one lives in the US. Let’s not forget the international audience of this forum.

@wklieYes that all works, but as I do often, like to listen to a few tracks of an album in the search results before deciding to add an album to favourites and without having to return to the main search view, what I am finding is that the ‘add to favourites’ option in the top left icon does not fully work. What does happen is that the icon for the album selected appears in favourites in the Qobuz app, but no amount of refreshes works to bring that album into Lumin app favourites. What only works at that stage is to open the album from favourites in the Qobuz app and tick the ‘heart’ option to turn the heart pink, as despite the icon being in Qobuz favourites view, the heart has not been selected.  There is a disconnect between the apps. 

If you press Add To Favorite there, doesn’t it place the track ”Honeysuckle Rose” into Favourites/Tracks folder?
 

Isn’t this window just for choosing a particular track as a favourite, not a whole album. 
 

And the heart doesn’t turn pink in Qobuz before all the tracks have been selected = the whole album.

Don’t sell them too cheap (so at least $299), the people who beg for these should also pay for them dearly. 😈

This is a potentially dumb question. I have an A1 and been using the Leedh volume control to connect directly to my amp. I am looking at potentially changing amps and noticed that the A1 has a max output on RCA of 2 VRMS.  Many amps have an input sensitivity of between 2 and 3 VRMS to drive to full output.  Is there any potential mod to increase the max VRMS over the RCA outputs? I suspect the answer is no but just wanted to check.

  I do recognize that the newer models went to 3 VRMS on RCA and 6 VMS on XLR. Thanks

 

XLR to rca cable is the potential mod.

LUMIN app uses 4.66 Gb of memory on my iphone, that’s an awful lot of those small album cover images...

[FIndingit]

I have 1041 albums and half of them don’t have cover art. I think the gigabytes are from Qobuz. 

[FIndingit]

And while you're at it, turn off the display and the network lights behing the unit.

[FIndingit]

I firmly believe in “less leds, better sound”. 
 

[FIndingit]

Do you completely turn off your phone/pad when you start listening and cannot check the sample rate on the app?

[FIndingit]

Since the wishing well is open, I would like to have:

 

- Qobuz pdf booklets on iOS app

- Larger back arrow on iOS app

- A way to hide some of the Qobuz album info (the year) in search listing to have more space for track names

- Even better sq

Here’s a cheap, quick, easy fix. 4x magnification. Just put it in front of the display. 

Fresnel

 

That’s it. Problem solved.

 

Now put all effort on pdf booklets. 
 

 

[FIndingit]

What I meant is why are some request more heartily accepted than others, no matter how trivial they seem to the average user.

Thanks for the reply. At least, a bit better. Still would prefer using the Lumin app, though. Out of curiosity (and also frustration), why is it you can’t just allow users to enable or disable music server/library?

Is this an Android problem? I have disabled the server function in the app somehow and it never pops up any windows in ios. It used to though. Shows only Qobuz and tuneln logos now. Maybe it helps that there are no servers visible in my network.

No, it’s on IOS. Do you remember how you disabled it? I cannot find anywhere to do that.

I’m afraid I can’t exactly recall how I got rid of the pop up screen.
 

Maybe you first have to have i.e. Minimserver running and choose a library. Then remove it. (Musiclibrary> Options> Remove music library, and it no longer automatically asks for it. 

[FIndingit]

The same thing (Qobuz login problems) happened to me just two days ago when my network was down several times in a row. Nothing helped, but I knew next morning it would be ok, and it was.

[FIndingit]

Having the traditional rocker power switch very close to the power input is often a best design practice.
