I'm afraid we don't have much newer AV receivers to test here. Anyway, you should use coaxial instead and it should sound better. Peter Lie LUMIN Firmware Lead Link to comment

Coaxial appears to work just fine although I cannot get .DSF files to play. Maybe I will have to get the Lumin to resample them to something more appropriate for my AV receiver.

No issue. For DSD trasmission over coaxial, on supported DAC we may set the "DoP" setting in Lumin app (analog output of DSD will be muted with this setting). However, I don't expect AV receivers to support that. So this is just FYI. Peter Lie LUMIN Firmware Lead Link to comment
Peter Smith Posted December 15, 2018 Share Posted December 15, 2018 I have a beginner’s question about connectivity for my newly purchased U1 Mini... I have an external hard drive full of FLAC files I’d like to use... and the U1 specifications talk about a USB input, but I’m assuming that the USB ports are both outputs so that’s why my USB drive isn’t being recognized... so, am I correct that the only way I can use this drive is via a NAS device connected to my router?

JMD54 Posted December 15, 2018 Share Posted December 15, 2018 No one of them is an input. Try the one closest to the Ethernet jack. Link to comment
Peter Smith Posted December 15, 2018 Share Posted December 15, 2018 Did that. Nothing. When I connect it to my PC, everything is there. The U1 just displays 2 folders, sda2 and sdb2. Any suggestions? Link to comment

Any suggestions? For the two USB ports on the U1 or U1 MINI, one can be used to connect to a USB DAC, and the other can be used for USB storage. Please check whether you see any music files under both folders. (FLAC, AIFF, WAV, etc.) Please make sure there is only one partition in the USB HDD. Every time you remove a USB storage device from the Lumin hardware, please power cycle the Lumin. If these do not solve you problems, please perform a check disk with repair using the computer. Then try again. If that still does not work, try to copy a few music files to a USB flash drive in NTFS format. Note: for exFAT, it must have one partition to be recognized. exFAT without being inside a partition is not supported. Peter Lie LUMIN Firmware Lead Link to comment
Popular Post Dan.B Posted December 15, 2018 Popular Post Share Posted December 15, 2018 @wklie Happy to report the Cisco switch was installed on Thursday, here we are Sat. morning, and Roon and Lumin have been working flawlessly. Can't say I really understand it, but I'm just happy it all works properly again (the whole reason I went with Lumin and Roon after having other more fiddly solutions)! Thank you all again for the quick feedback. thingswelike and One and a half 1 1 Link to comment

Your case is noteworthy because someone else has recently also tracked down his Roon problems to the same brand of switch you had. Peter Lie LUMIN Firmware Lead Link to comment
Hypercell Posted December 18, 2018 Share Posted December 18, 2018 @wklie Good morning Lie, I'm a very happy owner of A1 since almost 3 years and I have to say it is absolutely fantastic. I'm using files on NAS and Tidal. Since more than 1 year, after few monts that Tidal released the MQA files, It was not possible anymore to see the MQA list in the Master section (at the beginning it was possible) because it say that it is empty. I wrote to the Lumin and Tidal support asking for possible to fix the problem. Lumin said that the issue was in Tidal and Tidal of course said that the issue was in Lumin I don't know if someone else already ask you the same, probably yes but the thread is hudge. and I'm brand new here. Is it possible to fix this problem? Thank you in advance Maurizio Link to comment
wklie Posted December 19, 2018 Share Posted December 19, 2018 @Hypercell are you in Italy? A long time ago we already discovered the way we use Tidal API does not work for Masters folder if country code is set to Italy. I reported that to Tidal but it was ignored. At that time I found another manufacturer also suffered from the same problem for users in Italy. The Masters folder list is not a very useful one anyway - it is a human edited list of Tidal recommended Masters. For an almost complete list see the MQA_List.csv here: https://www.meridianunplugged.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=268318 You may also look for Masters albums by album or artist searching, then add them to favorites.

The Cisco switch SG112-24 is now sold at Amazon for less than $99https://www.amazon.com/SYSTEMS-24-Port-Gigabit-Switch-SG11224NA/dp/B00VPT8XSQ It is worthwhile to note because: 1. It has SFP slots to enable the use of the optic fiber network in X1 2. Even ignoring the SFP slots, people using other non-Lumin setup have reported positive results At least two comments say the Amazon photo is wrong, claiming their received product is the compact version instead of the larger rack mount version. In addition to fs.com and TP-Link SFP modules, I would like to report that a pair of this Cisco-compatible 1000BASE-LX module from 10Gtek (a brand only, does not imply 10GBase SFP+) also works with the quoted Cisco switch: https://www.amazon.com/dp/B00U8PN0NQ/ref=psdc_537316_t1_B0000AZJZL A Lumin X1 user told me in PM that with this setup "Music plays insanely.

Hypercell Posted December 19, 2018 Share Posted December 19, 2018 @wklie thank you for the reply. Yes I’m in Italy and I know that also Aurender is suffering the same problem but I didn’t know it was area related, so only Tidal can fix it properly. Actually I search in the desktop app and if there is something interesting I look up in the Lumin app. but thank you anyway for the list. Link to comment

Popular Post One and a half Posted December 20, 2018 Popular Post Share Posted December 20, 2018 Lumin U1 impressions The black Lumin U1 arrived to replace a USB to S/PDIF (AES3) front end. The main aim was to find a Roon end point for Ethernet, since the combos of achieving long distance USB where exhausted and AES3 over 25m was pretty good, the upgradeitis was just too strong. Involving the U1 replaced four components and two USB cables with trading the Ethernet input for those parts. Alternatives in the process were narrowed down to were DCS network Bridge, Bricasti M5, or a Lumin device with a DAC. For DCS, the priority to provide a path for MQA over USB output, while the manufacturer deemed this as necessary, was 'silly' in that the flexibility of the another output was denied. To this date, there's no USB output on the Network bridge, their decision. I trialled the Bricasti M5, and the USB or even the AES3 output was problematic for my ancient DAC at the time. The vendor offered the Lumin A1 for special price, and on the surface, the offer was attractive. but delivery problems for a black unit didn't happen that smoothly. Having a DAC inside a renderer made a choice of interfacing very easy, however, don't place all your eggs in the one basket. The U1 being a transport only offered a myriad of digital outputs to interface to any DAC up to DSD512. So the choice of the character of the DAC can be chosen. Programming from Roon was essential requirement, after being frustrated with uPNP's performance and reliability. Selecting a music to play from some 60,000 files with an up and down arrow is not the best experience long term. Also did consider an Aurender family component, but preferred the engineered approach and flexibility of upgrades to wit frequency of new features that Lumin provides, a comforting trait of the Lumin range where the models don't change that often. The Auralic G2 series were a hot favourite until I read the Aries G2 fell alseep and disconnected itself from the network. In addition there was some inconsistency with album artwork being displayed, that problem would fester into something major. There's a great deal of effort to embed artwork in the metadata, with small size graphic files to show up even on modest equipment. Well that falls out the window when bluetooth is streamed to car stereos, it's only possible to display album art with MP3, and I don't have any, too bad. Setup Setup with the Lumin app on the iPad is a no brainer. If you can set an audio device in Roon, the Lumin is just as simple. I didn't setup any music library, since Roon manages quite well and grabbed the closest CAT 5e Ethernet cable to hand behind the audio rack, the jumps to the music server are three switches and the router, so all the noise and traffic possible, why not? Output was AES3 Canare Pro cable to a Grace Dseign M920 DAC. Roon converts high rate DSD to PCM, so the U1 hasn't any work to do, just 'render'. In all, including an update and unboxing with the supplied white gloves took about 30 minutes to hear music. Initial SQ Well, @wklie advises a week of 24/7 playing, certainly good advice. The mids were very rough and undefined, aye karumba, the upper treble and bass reasonable out of the box. The sound is akin to the choice of a bad USB cable, veiled and cloaked in a haze. Never mind, after a few hours on Roon Radio, the haziness was less noticeable. 24 hours later and the SQ was very different. Open, solid soundstage, and great height, and very quiet 'blacks'. Bass was the best I've heard from digital in my system, full and tight, added great kick behind the music. Female vocals, like Norah Jones 'Come away with me' SACD had a commanding presence, with subtle details I've never heard before, even with headphones, coming out of speakers, impressive. Simon Phillip's drums come alive, picking up each skin, and none of that smear and confusion. Cymbals are to die for, the decay is magnificent. I have to be careful, since I'm evaluating the DAC as well, but it must be fed a great signal in the first place. That's just 24 hours of burn in time, so what's next!! A JCAT Ethernet card also arrived, to provide a direct path from the Supermicro Music Server to the Lumin U1 via bridged arrangement. I've dabbled in Ethernet bridges before, looks straightforward for this setup where the Lumin requires DHCP to work, so there's some re-routing to do on the weekend. Fidelizer was changed to a network player profile, whatever that software setting does, just works in removing a layer of unnecessary Windows processes, certainly doesn't sound worse. After the weekend will report on the JCAT and any changes with the U1, so far, very good indeed, very pleased. audio.bill, kelly200269 and wklie 3 AS Profile Equipment List Say NO to MQA Link to comment

The U1 needs a better location and is 4m away by cable distances from its current position. So that means extra cables which I don't have as yet. 4m of coax cable, and have decided to go high spec with RG-6/U capable of several hundred MHz, so 192 kHz should be fine. It was quite a challenge to find the F to BNC and RCA adapters for 75 Ohm cables, but should have tried Mouser first. For the cable, Belden have a full foil shield copper cable, here's the detail. I had to buy a 100m reel, but it's less than USD150 for the 100m. Can use the same cable as an upgrade for FM tuner feeds and other digital input cabling, so the remainder can be used. I did look at the Nordost Valhalla and Heimdahl digital cable, the prices are horrendous like the Black Cat. AS Profile Equipment List Say NO to MQA Link to comment
