Lumin - Roon ready

It’s possible with either QNAP with added RAM running RoonServer, or Mac Mini running Roon. It’s not possible if you don’t run Roon on anything (computer or NAS).

When you use Mac Mini running Roon and use a Roon Ready player, the Mac Mini sends music data via network to the Roon Ready player - the Mac Mini does not perform the task of a player in the traditional sense. The Roon Ready player is not directly attached to the Mac Mini, so the Mac Mini can be physically far away from your Roon Ready player.

If you have not paid for a Roon subscription yet, you may also consider installing the freeware MinimServer to QNAP, then use Lumin app to control the D1 using iPad. Mac Mini is not involved in this case.

I have iMac, Macbook Pro and Mac Mini, if I use one of these to run Roon do I have to leave it on 24/24 ?

and what Roon do you refer to? Is it Roon Server or Roon Core ?

PS: I have bought full version of Roon so I have to stick with it.

If you have multiple computers to choose from, choose one which has SSD (to store the Roon database), and a faster CPU. I think (but am not sure) you can turn it off if you’re not playing music, please check other threads on this, e.g.:

When I said Roon I refer to both Roon Core or RoonServer. On Mac I think it’s more convenient to have Roon with GUI, but if you don’t need the GUI you can use RoonServer instead.

Hi Peter,
I think I will upgrade the QNAP to run Roon Server, only that way I can get rid of the Mac Mini.
If I can use QNAP to run Roon server, and Lumin as network player + DAC, I can also get rid of my current DAC which is Bel Canto 3.5.
I’d love to have a minimal system as possible, but I also want good sound. I think Lumin is a good choice.
Thanks for all the information, much appreciated.

I found a post on another forum, stating:

Lumin HDMI port conforms to standard HDMI - it can output PCM or DSD to an AV receiver. It does not do I2S over HDMI, which is non-standard.

I’m looking for a mod to get IIS from my T1 Roon endpoint. I like IIS best as an interface to my modded Gustard X20. Using BNC now, not my favorite.
Can it be done?

That was written by me.

Sorry, Lumin does not output I2S to external DAC. Please do not attempt to connect Lumin HDMI output to your DAC HDMI I2S.

Thanks! I don’t get the decision to include the PSU internally

Follow-up question for Peter - is it a linear PSU design or SMPS inside?

We have received request to move the Lumin D1 power supply from external to internal, because they considered the external power supply to be inconvenient.

Responding to that request, Lumin D2 with the new internal switching power supply offers better sound quality, in terms of clarity and imaging, than D1 with the original external power supply.

For customers who prefer to use an external LPS such as Sbooster, we have reserved a limited number of units of D1.

A step backwards if you ask me. Pretty much everyone I know uses D1 with an external linear power supply

Hi Peter,
Any chance for our D1 users to upgrade to D2 with an additional cost? I love mine Lumin but it would be great if it can support DSD 128.

Since we do not currently provide any upgrade plans, your best option is an external LPS.

Hi Peter, I have upgraded to the Sbooster PSU and it works really nice with the Lumin. Thank you

Just got the D1 w/ LPS and can’t believe how good it is out of the box!
I previously had a NUC w/ ROCK directly feeding the pre/pro’s (Classé SSP) USB DAC. Now, I moved the NUC out of the way, running balanced XLR to the SSP from the Lumin and it sounds so much better.

How come there’s no ‘track count’ when tracks play through Roon? As with the Lumin app, e.g. ‘4/10’ (playing track 4 out of 10)
I’m sure there’s a perfectly logical explanation, just being curious!

That’s a good question. Last time I checked Roon does not provide this piece of information to the endpoint via the RAAT SDK, so we are unable to display it. In this particular case, it is perhaps not very meaningful for a consumable queue.

@wklie. Does the Invert Phase function in the Lumin app work on the fly when playing through Roon? Or is there some sort of delay or reset involved? Thanks

It should take effect immediately, although the behavior is different when playing from Roon and from Lumin app.
