    Re: Lumin T2

    Has anyone tried an external linear power supply with the T2? Looks like Sbooster provides a connection kit but it does require you to open the Lumin up to make the slight modification. I'm guessing that voids warranty as well.

    I would try it, sbooster is well regarded especially for the money.

    All Lumin products to be shipped back for repair must have original parts inside and intact.

    Fine. As long as the original box isn’t required. I have gotten tired of saving gear boxes.

    I don't use USB.
    Just to be sure, the BNC output is male — so the cable on the T2 side must be have a female termination?

    Re: Lumin T2

    Instead of playing around with fixtures inside Lumin T2 , i would rather opt. for an S1....that way you will also have the benefit of the external power supply , meaning that you can easily switch it for another Power supply if you want that.
    And soundwise the S1 is good step forward in sound. ( its a big step )

    Re: Lumin T2

    My point is that tearing into a built unit and distroying a warranty with no proof of benifit and hoping to get better performance can at best only have a placebo affect. I chose to improve my power supply dc cables to my modem and GigaFoil along with better ethernet cables. Clean up everything that gets to the Lumin first. Or as you pointed out a digital streamer with a separate power supply makes more sense.

    Re: Lumin T2

    Hi All,

    I just want to throw in my two cents on this thread. I bought a Lumin T2 a couple of weeks ago and I’m thrilled with it.

    My system is an Ayre C5xeMP SACD player, Ayre AX5-20 integrated amplifier and TAD ME-1 speakers, hooked up with Transparent Cable in a small room in a high rise condo. I was initially going to buy a new SACD player but decided to try the streaming route. I’ve never streamed music before, not at home or on my phone.

    I decided on the Lumin based on the reviews and the specifications. I liked the form factor and the fact that it had everything I wanted (balanced outputs, Ethernet connection) but nothing I didn’t want (hard drive, CD burner, WiFi).
    It took me about 5 minutes to plug the Lumin into the Ethernet jack nearby, into the amp and into the wall, another 5 minutes to sign up for Qobuz, and music was playing! I let the Lumin play continuously for four days.

    I am very pleased with the sound. In CD res or high res, it is at least as good as my disc player, and has better low end. And what a world it has opened for me- there are many, many albums that I would liked to have heard over the decades, but didn’t want to invest $15 for a CD or $30 for an SACD, yet now they are available at my fingertips. I’ve been very pleasantly surprised at how many albums of all genres are available in high res. Two examples. In rock, I’ve never liked the Doors enough to buy an album other than Greatest Hits, but now I’ve been able to explore their whole catalog. In Jazz, I’ve liked some albums, but never knew enough to invest in individual CDs/SACD’s. But now I’ve been listening to a lot of classic Blue Note jazz and liking a lot of it. As far as I can tell, I’ve sacrificed nothing in sound quality but expanded my musical horizons immensely. The $25/ month for Qobuz more than pays for itself by not having to buy new CDs/SACDs.

    Finally, a note on Lumin’s customer service- as I said above, I’ve never had an iPOD, used Pandora, Spotify etc, so there were some things I could not figure out how to do by playing with the Qobuz APP or the brief Lumin users guide. I sent a long email to Lumin the day after I got the streamer, and the next morning I had concise but detailed answers in my inbox. Couldn’t ask for more.

    One more benefit of the Lumin- spreading the word. On Saturday night we had an impromptu get together of friends after dinner. I asked if they wanted to listen to music. In the past, whenever I had someone over and they wanted to listen the conversation would go like this: “Tell me what you’d like to hear.” “Whatever you like”. “No, to appreciate the stereo, you need to listen to something YOU like”. “OK, how about David Bowie” (or some Jazz artist, or classical, or Led Zeppelin or Coldplay, etc). “Sorry I don’t have that”. And they would squirm as I put on some Dylan. But Saturday night- I played DJ, some stayed on the sofa listening intently, some danced, and everyone had a blast for 3 hours (the wine helped too). All agreed they could hear a big difference between my stereo and anything else they ever heard.

    Long term, I can see the Lumin replacing all my SACD’s and 90% of my CD’s, and limiting new purchases to CD’s from obscure bands I hear live.

    I wish I had taken the plunge sooner.

    Regards, Dylan.

    Re: Lumin T2

    Thank you. I'm more of a reader than a poster. I did post an extensive personal audio history on another forum a year or so ago. But lately I find Audioshark to be the most enjoyable forum due to the diversity of topics (not just ultra high end), the collegiality/lack of snootiness, and the owner (Mike) appears to be a class act.

    Re: Lumin T2

    In other forums I read, some people would consider CD player superiority over streamer playback to be common knowledge - although I suspect people there are using a PC + Tidal desktop software + USB DAC to compare with a CD player. I'm glad you find your T2 to be as good as or better than your CD player which costed 33% more in MSRP (even more if including inflation), disproving this myth.

    Re: Lumin T2

    Don't think its a fair evaluation comparing a AYRE CD Player that came out in 2004 vs a New Product. If you were comparing a TOTL Esoteric, Luxman, Chord Dave/Blu2 etc disc spinner that's currently in production and told me the Lumin blows them away then I would be impressed.

    Re: Lumin T2

    I understand what you're saying, but this is all I can do for a comparison. One data point however- after I bought my speakers a year ago the dealer lent me a TAD SACD player that had just come out. I thought it was marginally better than the Ayre, but not worth the price difference. So I think the Ayre is still pretty good, even though >10 years old.

    Re: Lumin T2

    Hi Dylan, and welcome to the forum. I'm also a new owner of the T2 and have found it to be a real pleasure to use. I added a lot of other things in my system at the same time as the Lumin. So, my impressions of the T2 were more a part of a lot of additions in my streaming system. Probably not the best way to go. But, what are you going to do. I'm also a big fan of Ayre equipment and owned the CX-7e Cd player. Loved that player. At some point you may want to read through the GigaFoil thread if you haven't already. That or other additions for streaming could surprise you as well.

    Re: Lumin T2

    Thanks Darrel, I appreciate the advice re Gigafoil. But for me, after reading 13 pages of the thread (on vacation today, sitting by a pool) I don't want to go down that rabbit hole. And what a rabbit hole it seems to be. For me, my personality, and my stereo, I'm quite happy leaving well enough alone and enjoying my newfound music. Regards, Dylan.

    I agree. Enjoying what you have should IMO be the main goal. It's easy to keep adding and chasing to the point of never just enjoying what you have. But, incremental changes over time can yield benefits. Enjoy the pool.

    Re: Lumin T2

    Does the 9028PRO in the T2 convert DSD to PCM? I know many DACs do this to process DSD, but I am looking for a solution where there is no DSD to PCM conversion by the DAC.

    The short answer is no. Long discussions can be found here:
    https://audiophilestyle.com/forums/t...comment=322890

    If you want DSD that is more pure, you can play DSD64 in Lumin D2, or you may get one of the very few brand new remaining units of A1 we have.

    Re: Lumin T2

    Breaking in the T2. I have noticed a definite improvement to the sound of music streams played through the T2 the more I have been using it. At this point some of the more clinical aspects of the music have receded, making the experience far more pleasurable. However, as soon as I have stopped listening, the T2 pauses and then eventually turns itself into standby. I would rather not have to listen to the next 75 to 100 hours. Is there anyway I can enable the unit to download, decode, convert and output from, say, Tidal with my preamp on standby and me absent from the room?

    Please add some music (of different sample rates and PCM / DSD formats if possible) to your playlist from your music library or Tidal / Qobuz, and turn on repeat.

    Re: Lumin T2

    Hi Guys, quick question on the overall tonal character of the T2. I am almost done burning it in and so far really love the transparency, detail, and soundstage. The only thing I am grappling with is that it is a tad bright in my system (Luxman 509X + Martin Logan 11As).

    I know the MLs are generally not bright speakers, tending to roll off highs, though they are transparent. They generally don't pair well with an overly warm amp, with the McIntosh MC452 the highs felt a bit mushy. I am thinking it's the Luxman + T2 combination, which is incredibly transparent.

    Just curious what everyone's thoughts are on the tonal characteristics of the T2?

    Slightly warm IMO. What Ethernet cable and power cable are you using on the T2?

    Thanks Mike, that's what I figured. T2 is one of the best streamers I have heard.

    I am using a generic Monoprice CAT 6 ethernet cable.

    Re: Lumin T2

    I have now streamed more than 200 hours of music through my T2. The sound overall is now much better, if my memory serves me, than it was when the T2 was brand new.

    So I have a question: why? What actually is "breaking in"? Physically, what is happening -- with the ICs, with the other components, with the wiring between components (cabling and tracing on circuit boards) as well with the interconnect cables and power cord -- that results in an improved sound?

    As I told you on May 18 via PM: "The T2 needs 7x24 burn-in for more than 2 weeks." I'm surprised you only reached 200 hours just now. Please really play it 7x24 with repeat on, and turn off the power amp if necessary. A Lumin is super easy to burn in and with minimal power consumption (as compared to other things like power amps or speakers), please take advantage of that. (There was a reviewer who claimed he needed 1 month 7x24 to burn in the S1.)

    I really hope it'll improve for you since your initial impressions of T2.

    Is it possible for the total number of tracks (2000 at the moment) that can be saved in the playlist, be increased to 3000 or even 2500?

    Peter, how would you describe the T2 sound before break in compared to after break in? Thanks.

    Re: Lumin T2

    I'm not expert in describing audiophile SQ, so I tend to leave it to reviews and users. I'll only say it should sound even better after sufficient burn in, as a user found out a few posts above.

    As for matching with your MartinLogan Expression ESL 13A (that you mentioned in a different forum thread): Some dealers may be able to loan the T2 to you for trial. After you get a Lumin, burn it in for as much time as the trial allows, and experiment with non-upsampled music or try upsampling to DSD(128). If you're a Roon user, you may turn off the Lumin upsampling and use Roon DSP Engine to upsample DSD512 if desired.

    Re: Lumin T2

    Now that I have thoroughly "broken-in" my T2 -- and find its streaming/DAC functionality sonically outstanding -- a new problem has suddenly developed: the Lumin app will not connect with my T2. Essentially, I can reload the app, and it displays on my iPAD 4, but (1) when I tap the little gear button and then the Options tab, none of the commands (starting with "TIDAL Setting") are operative, and (2) the entire page becomes completely frozen. As a consequence, I can only use my Roon app (through a Nucleus + core) to enable music to stream and be "DAC'd" by my T2.

    I have tried to resolve this problem myself. Here are all the steps I have taken -- all have failed:

    1. Completely erased the Lumin app from both my iPAD mini and its stored version in my iCloud and then reinstalled.
    2. Did the same with an iPAD 4 and my iPhone XS.
    3. Since my Internet is provided via DSL, replaced the modem with the latest version available from my ISP (CenturyLink).
    4. Replaced the five-year old Cisco managed switch resident on my AV equipment rack with a new Luxul 24 port AV-optimized unmanaged switch. (Now my entire Ethernet data path from the wireless/wired router to AV switch is all state-of-the-art Luxul.)
    5. Turned off the firewall protection function of Norton 360.
    6. Used two different Shunyata power cords to connect the T2 to my Denali 6000/S power conditioner.
    7. Used three different Ethernet cables (Audioquest, Wireworld and "CenturyLink-provided industry standard") to connect the T2 to my Luxul switch.
    8. All of the software is up to date (except I cannot verify that for the T2 since I am unable to use the app).
    9. Of course, I have rebooted not only the T2 numerous times, but have rebooted each component in the chain -- starting with the modem -- in a cascade several times, too.

    Nothing seems to resolve the problem. The Lumin app sees the T2, but when I try to use it, the page always freezes.

    I use the Fing app to monitor the performance of my system. Running a Ping test, the average ping of my Nucleus + is around 4 ms. Before typing this posting, I ran the same Ping test on the T2; its average Ping was 147ms, with the minimum of 30 Pings being 3.5 ms and the maximum being 312 ms. The standard deviation of this test was 91 ms. I have run this Ping test many times; often the T2 completely fails to successfully Ping even once in 30 attempts.

    I am at a loss. What do you suggest?

    No. Streaming never reaches the SQ of a CD.

    CD = 10/10
    Streaming = 8/10 to 9/10 depending on a number of other factors.

    Please power down Lumin T2, iPad, and all network devices. Power cycle the WiFi router and all network switches / access points. Wait for 5 minutes then power up the Lumin and iPad.

    From a specification point of view, both Tidal and Qobuz offer the same class of lossless 16/44.1 CD-quality with the appropriate subscription. In addition, Tidal offers MQA for no additional cost, and Qobuz offers Hi-Res for a higher subscription price.

    Does an upgraded power cord for the T2 make a difference in sound quality (not sbooster discussion but the power cord itself)? If so, any suggestions?

    I’ve own two Lumins - S1 and X1. In both cases, upgrading the PC has brought very good improvements. I’ve used Shunyata Alpha and Sigma with the Lumins with excellent results.

    For a more reasonable option, the Shunyata Delta is worth a try.

    Peter,
    Any chance you could add a function similar to what Auralic has in their Lightning DS platform called Flexible Filter? I think it controls the general sound characteristic of the dac. Choices are Precise, Dynamic, Balance and Smooth. The reviewers seem to like the changes in sound quality it makes. I have a friend says the Smooth setting makes his Altair sound more tube like.

    Since Lumin does not support DSP, please try Roon DSP Engine.

    Re: Lumin T2

    Thanks Peter. It would be nice to have those settings available from within the Lumin app itself rather than having to subscribe to roon. What is it about lumin's software that does not allow it to support DSP where another vendor is able to do so. Is it possible for you to add DSP support since another vendor was able to? I think it would give Lumin another edge in the marketplace.
