Lumin X1

wklie said:
With X1 and T2, audio output needs to be chosen in the setup: analog, SPDIF or USB. As part of the QC process all output modes would be checked. Normally it would be reset back to analog before shipping, but this is complicated by the cached (delayed) nature of data saving. We have been taking steps to avoid this, and added the factory reset function in the Lumin app a few days ago.

Please create a playlist of different sample rates / PCM and DSD, play 7x24 in repeat mode for 2 weeks or more.

Note that connecting both XLR and RCA outputs will degrade the sound quality.

i have a new X1 with the analog output going to a power amp. I need to use the USB output to drive a headphone amp with built-in DAC. I have the setup set for audio going to the analog output. Will the USB port produce the desired output (digital)? Will it be a fixed level?
Thanks,

The USB (or the SPDIF) output port is not fixed level. It is also affected by the volume in Lumin app.

If it's controlled by the volume control, that implies that there is only one active audio output at a time. Is that true? If it is I would have to go into settings and change it whenever I wanted to have the X1 support a different device. I was using the USB output port to drive Aurender Flow headphones from my Aurender N10 while being able to listen to music from my speakers at the same time. I didn't need to reconfigure anything.

Yes, in the Lumin app X1 options, you choose which output is active and only one is active at a time: analog, S/PDIF, or USB. Volume control affects all three outputs if you have enabled volume control.

Personally that works well for me because it lets me have multiple things hooked up at once but only have one output active, and to switch the active configuration from the Lumin app.
 
I turned the volume control off and I’ll use the volume control in my integrated amp. It has a remote and a headphone amp.

i suspect the reason Lumin limit the audio output is because everything goes through output transformers which probably can only deal with one device at a time.

That is true. For Lumin X1 and T2, only one output is active (analog, USB, or BNC-SPDIF) and needs to be chosen using Lumin app.

On our older products the analog and BNC-SPDIF were active at the same time, but this design causes confusion with raw DSD not output to SPDIF, DoP signal not output to analog, MQA full decoding not output to SPDIF, MQA core decoding not output to analog, etc.

After going to be 5years with A1, this is it!

Your post of using Lumin A1 with FMC for network isolation first got me interested in this subject. So you have yourself to thank for the fiber network capability in Lumin X1!

Really appreciate for listening and taking up value of our feedback, great product for Peter and Team!

I am considering going directly from the X1 to the input of the P.A.s through a high quality XLR I/O switch box that would allow the X1 to go to either the preamp or the poweramps and the power amps getting its inputs appropriately. What were your impressions of sound quality of the X1 with the volume control function engaged? I've heard that the sound quality changes but I am not sure how and I never did explore this possibility with my current S1.

i had the volume control active by mistake and turned it off as soon as I found out how to do it.
Consequently, I never used it.

Here's the latest review of the Lumin X1 from Stereo Magazine in Germany, where they award it a 100% in Sound Quality! The review begins on page 12. :congrats:

I look forward to the review!

I just installed my X1 after updating my network infrastructure to a 10GbE fiber system with 1GbE SFPs on the Lumin. It fired up immediately, found an I.P. address and I've got a couple of hundred hours of music cued up to run even though the amplifier is currently off. I am expecting great things out of this machine and I think Lumin for providing the white gloves to treat the X1 with the respect it deserves.

One note of caution for those like me who are overly anxious to get the system installed: I inadvertently connected the male end of the power cable into the male power connector on the X1. NOT A GOOD THING! I only discovered my error when I tried to connect the female end of the power cable into the female connector on the power supply. Luckily no damage was done, no pins were bent, and I was able to make the appropriate connections and power up the system.

P.S. The footprint on the new power supply provided with the X1 is larger in width than the one on my S1 and I had to adjust things accordingly. Oh well..............

P.P.S. The review indicated that Lumin packed an SFP module in the box for making the optical connection. I did not receive an SFP module with mine. This may have been a courtesy to the reviewer however.
 
I have a question about the X1 and its power supply's physical positioning.

The horizontal space between the uprights in my rack were adequate to fit my old S1 and its power supply side by side. Not so with the X1 so I temporarily installed it onto the shelf above the X1. My question is twofold: Would it be okay "sonically" to install the X1's power supply on top of and in the middle of the X1? Most of me says "of course it would be okay" but then again who knows..... The second part of the question is are the feet on the X1's power supply "inert" and would not lead to depositing any sort of "gunk" onto the the brushed surface of the black X1 or otherwise lead to potential damage to the anodizing? I know, I know......... get a grip and don't go all OCD on us.

Thank you for the suggestion.

I will not stack them but am curious as to whether this is for sonic or other reasons? I remember seeing an X1 atop a Lumin Amp, probably on the Lumin website, and didn't know if that was an example of an operational setup or for the photo op only.

Also, and I am not sure if this is the most appropriate place to ask but I was watching network traffic over the fiber connection in and out of the X1 and it appeared that the network was idle for much of the time. It got me curious as to what really happens when you hit "play" on the Lumin iPad app. I may have the answer to this first question already: Is the entire playlist transferred to the X1's memory? Because I can shut down the iPad and music continues to happen I assume the play list is in the Lumin and it asks the server for more data when it needs it. Then I thought about how much music is being buffered into the X1 and can the X1 continue to play for a period of time if the network connection is severed, etc.

If the question is out of scope for the thread or would divulge commercially sensitive information no worries or if there is an article on the web I will try to find it in lieu of tying the forum up.
 
It is true that music playback continues even if the iPad is shut down - that's a design goal and has always been true since the introduction of the first Lumin at the end of 2012.

The (current) playlist metadata is relatively small and is inside the Lumin memory. So Lumin can ask the MinimServer on NAS to get the music data as needed without involving the iPad. The actual music content is adequately buffered in memory as well so you can have a short time of playback even if the network cable is disconnected, or a momentary interruption from internet streaming.
 
Thanks wklie!

Lumin seems to like MinimServer and has based a lot of its testing and development in large part on MinimServer. Also, QNAP has MinimServer built in which is an added bonus.

I have tried MinimServer and it works well but there is one aspect of it that is lacking and, therefore, have chosen JRiver MC instead. JRiver allows you to associate "tag" information to certain file types, WAV, etc., that MinimServer doesn't. Of course, MC is not entirely "clean" when paired with a Lumin but it is something I've learned to deal with.

Do you have any idea if MinimServer is looking into this a a potential future enhancement?
