  1. Although I think you're right, I also suspect the truth is more complicated. In the past, TP-Link gigabit FMC really did not connect at 100Mbps - I believe I've read a few people having trouble with that across forums, and I even have a few in our office that behaves this way (that forced me to upgrade an old 100Mbps switch to a new gigabit one). I think another member here actually recommended Trendnet over TP-Link for this reason. If we check the web archive, we see the specification has been changed: https://web.archive.org/web/20180114023115/http://www.tp-link.com/us/products/details/cat-43_MC220L.html#specifications Not only is the MC220L specifications changed. MC200CM and MC210CS specifications are also changed - which is not surprising. For some reason many consumer network equipment manufacturers make really different hardware revisions continuously without making them public and clear. I think I've also seen cases of routers using a totally different chipset without changing the model number - this makes firmware upgrade confusing and risky, and is especially bad for people who want to try third party firmwares. Since @the_doc735 believes he might have got a faulty used component in the first place, the solution is not related to the 100Mbps issue, but I still want to make this clear so that people have more information when they troubleshoot their FMC setup in the future.
  2. For those interested in another subjective review of SQ from fiber vs copper Ethernet from Lumin X1, I've translated parts of a review from Taiwan:
  3. On the subject of SFP modules, at Lumin we tested several (not exhaustive) combinations of single mode / multi mode / wavelength / km / vendor compatibility (Cisco, Intel, Dell) of SFP modules from fs.com, a few single mode / multi mode modules from 10Gtek available from Amazon and our local physical stores, and a few TP-Link single mode / multi mode modules against four brands of SFP switches, and TP-Link single mode / multi mode FMC. Since we do not support 10G, we focus on gigabit modules only. We even tested some copper Ethernet RJ45 SFP modules. On the whole we did not experience any unexpected incompatibility.
  4. Lumin X1 review from Taiwan: https://review.u-audio.com.tw/reviewdetail.asp?reviewid=1617 My translation of some parts of it: [brackets are mine] [Lundahl Transformer] For the output, X1 not only has analog RCA and XLR outputs but have digital outputs as well. Therefore it can be used as a pure streamer [for an external DAC] too. Analog outputs adopt a design similar to some Lumin models before - there are Lundahl output transformers following the DAC hardware circuitry so that the amplified signal goes through the transformers before being output. Why does it need this extra hardware? This is because output transformer has a characteristic of filtering out high frequency noise. Transformers have a native bandwidth limitation, so signals outside the bandwidth do not get transmitted. This way, very high frequency noise associated with digital audio is naturally eliminated. In addition, output transformer has a tuning effect and make the sound richer. [Fiber network vs copper network] Before getting the X1, I'm very curious about its SFP fiber network interface: What SQ difference does the SFP fiber network offer as compared to RJ45 copper network? If we need to do this comparison [completely], both the NAS and switch should use SFP connection, so the distributor lent us their QNAP TS-251B NAS and QSW-804-4C switch. QNAP high-end models of NAS have expansion capability, including this TS-251B with a QNAP LAN-10G2SF-MLX network card with 10GbE using SFP+ interface. The QSW-804-4C contains both RJ45 and SFP+ ports, letting us conveniently compare the sound difference between the two. To listen to fiber network, use fiber cable to connect to the switch and the NAS SFP+ port. To listen to copper network, use RJ45 network cable to connect to the switch and NAS built-in Ethernet port. [Note: Unlike what this review may imply, it is not essential for the NAS to have fiber network in order to enjoy the fiber network in Lumin X1.] This is QNAP QSW-804-4C with both RJ45 and SFP+ ports. The fiber in the left connects to the X1 SFP port. The middle RJ45 connects to [uplink] switch. The black cable in the right connects to the NAS SFP+ network expansion card. Fiber network requires a small SFP transceiver. This is QNAP TS-251B NAS with PCIe expansion slot filled with QNAP LAN-10G2SF-MLX network expansion card to support SFP+ 10GbE transmission. What are the differences between the two sound? SFP fiber has a black background with a pure sound, it feels more liquid, soft, delicate, layered, balanced and open. RJ45 copper network has quite a clean background, but sounds to have a little impurity compared to fiber network, the sound has a bit high frequency frizz and is less smooth than fiber. However, RJ45 is sharp and energetic. Comparatively, fiber seems a bit softer. In terms of soundstage, RJ45 is more focused on centre and saturated with a clear theme. Fiber expands to two sides and is more open and is extremely balanced. Basically, I believe fiber and RJ45 has different personalities and each has its pros. Objectively, I believe fiber offers more details, layers and is full of potential. RJ45 is more variable depending on the cabling. X1 provides two types of connection and two sounds to choose from, letting the user to match their own equipment and tastes. In addition, Lumin also allows for another type of connection topology: use the X1 RJ45 port to connect to the switch, then the SFP port to bridge the NAS SFP+ network card. This way, a SFP switch is not necessary to enjoy the advantage of fiber network. [Listening Impressions] The following review uses Electrocompaniet EC 4.8 pre-amp and NuPrime Evolution One amp, driving Aurum Cantus Grand Harmony speakers. I quite like the pure sound and smooth voice from fiber, and the rich layers and contrast brought by full details. So I start with fiber listening, playing Janos Starker, Bach Suites for Solo Cello. With the support of X1 black background, rich details from SFP fiber are more obvious, letting me hear that when the bow hair stops, the chamber resonance decays gradually in the air. In double stops, the resolution between two notes is very good, reflecting the details. The cello sounds a little sticky, not deliberately polishing a bright smoothness, giving the texture of friction among the strings. In addition, the shape of the cello appears very correct, with a precise image and proper scale. Low mids sound a little wet, making the tone more attractive. Cannonball Adderley, Somethin' Else: X1 soundstage is more focused and centred, especially suitable for a small Jazz band. Through the X1 playback, each instrument, each drum beat is shown with precise imaging, with excellent separation between each instrument, letting me "see" the band with realism. Besides, X1 not only plays with clear imaging, but different frequencies and proportion of sounds are strictly presented without blurring or exaggeration, and it does not have bloated bass. X1 also supports Roon Ready in addition to UPnP OpenHome, letting me to listen to familiar music from my Roon Server on QNAP HS-453Be [TS-453Be ?] NAS. My HS-453Be does not have the fiber network card, so it is connected via RJ45. In this setup, Janos Starker, Bach Suites for Solo Cello plays with clearer shape of strings with even better contrast, giving deeper musical emotion. Eric Clapton, Old Love: X1 is adept at this. Weak sounds are presented without strain. Strong sounds play with rich layer variations. It combines with transparent tonality and appropriate liquidity and wetness, listening to this feels great, and 13 minutes do not feel long at all. Chris Babida, Tsai Chin, To Encounter - Chris And Friends track 1: X1 once again presents a focused and centered image with a clear shape as its strength, making the voice realistic with a dense texture and temperature thereby making it deeply emotional. I believe X1 will absolutely charm audiophiles who like listening to voices. X1 is so great at Bagatelle music, Jazz and Rock, what about symphony? With 37th Tapei Int'l Audio & Art Show CD: even though the X1 soundstage is not too wide, the structure of the orchestra is very excellent - treble, mid, bass distribution is orderly and not messy. In particular, the front, mid, back separation and layers can easily be recognized. The resolution of whole frequency spectrum is equally good with a clean bass. Even complex music is handled by X1 easily. It is not common for a source to be like X1 that simultaneously has rich functionality, convenient operation, elegant appearance, small physical size, HiFi grade design and manufacturing, and high level of audio reproduction, fitting any requirement of any demanding user. X1 also offers a rich listening experience, through its fiber or copper network, or its upsampling, bringing different tuning possibilities for sound quality. X1 is not complex to setup yet it has the most complete specifications and supported services. X1 will not disappoint.
  5. So, the MC220L + Cisco compatible SFP did not work in your setup, but the MC200CM does. Is this correct? Any other conclusion for MC220L and SFP?
  6. I look forward to your test results. How do we know it is genuine Cisco, other than a label?
  7. Assuming our Japanese distributor supplied all the optical network hardware for this review: https://online.stereosound.co.jp/_ct/17250487 Then it may be TP-Link MC220L - just a guess.
  8. A Japanese audio magazine also compared single mode and multi mode, and they preferred single mode and chose it for their review (in conjunction with SOtM sNH-10G): https://online.stereosound.co.jp/_ct/17250487
  9. @mav52You may try this: Or the more expensive fiber optic based isolation product just above the linked post.
  10. Have not heard of any plan for that. Even if I have, I'd not be able to disclose it.
  11. Which version? 1099c? Thanks. Reading this https://github.com/lintweaker/xmos-native-dsd/issues/12 Based on the posts there, it seems that some people still have various issues, or not able to get DSD512 to play perfectly.
  12. For gigabit connections, some of our users have good results with MC210CS - no SFP required so there is no converter/SFP compatibility to worry about. For the exact product links involved, see https://audiophilestyle.com/forums/topic/14016-lumin-audiophile-network-music-player/?do=findComment&comment=922819
  13. I think it's best you ask Sonore for recommendations and compatibility with specific FMC before making any additional purchase.
  14. I incorrectly assumed most PC nowadays have gigabit Ethernet, since your PC is 100Mbit only the TP-Link gigabit FMC is not going to be compatible, sorry about that. Do you have any other device that has a gigabit Ethernet port to verify your FMC setup? NAS?
  15. If you use a pair of TP-Link MC200CM, set it to forced: https://www.tp-link.com/us/faq-1135.html I'm not completely sure for MC220L though. Note that TP-Link Gigabit FMC is not compatible with 100Mbps Ethernet. Try this setup to verify your FMC is working: Router or switch - (network cable) - FMC - (fiber) - FMC - (network cable) - computer
