    Re: Lumin D2

    If the D2 is the model without the ability to use an external power supply, I’d get a D1 while you can. The D1 is superb.

    Re: Lumin D2

    Unless there are things the D2 can do that the D1 can't, it may make the D1 retain a nice resale value. I have not heard the D1 (have a U1) and briefly considered selling my second system DAC (which I can probably sell for a little bit more than the D1 plus a power supply) and buying a D1 (more for the fact that I have a Windows based music server) but the amount of time I use the system is not that much and it sounds superb so I left it alone.

    Well that's cool. I wonder how it will compare sound wise to my D1 with a external PSU.

    Re: Lumin D2

    Lumin D2 uses an internal switching power supply that is better than the external power supply supplied with D1. Combined with improved digital circuitry and the proven analog design, the imaging and dynamics are improved. D2 also comes in black and silver versions.

    For those users who are interesting in using an external LPS such as Sbooster, we have reserved a limited number of D1 units.

    This website (in Chinese) shows more photos of D2:

    This begs the question: Which sounds the best? A D1 with external power supply or D2 with new internal power supply?

    Peter would know best based on user feedback, but I'd expect it to depend upon the quality of the external supply.

    Great question. I will be buying a DAC and Streamer/Player in December or January and would love to know what Lumin’s upgrade plans are.

    With D2 compared to the D1 with original power supply, D2 sounds better.

    If you're asking for a comparison with the D1 with Sbooster, we won't be able to answer this question as we don't even have a Sbooster. Please consult your dealer.

    Same here. I like that D2 has internal power supply. But I'm mainly looking for a streamer/player and D2 DAC section maybe redundant for me. Wondering if Lumin has any plan for a D2 version of U1.

    Re: Lumin D2

    I found the following in the public domain comparing the D1 and D2 in the event anyone is interested:

    Differences we found on line for Lumin D2 and Lumin D1
    - new generation CPU in D2, slightly faster processing speed
    - D2 includes an internal 100/240 volt "switch mode" power supply in place of the D1 wall wart (Maybe from the Lumin M1 integrated amp/streamer)?
    - The D1 allows for an optional Sbooster, external linear mode AC to DC power supply upgrade, the D2 cannot accept this option. D2 is AC powered.
    - Logic and listening tests suggest better sound quality in D2, when compared to a D1, if and only if the D1 uses the included wall wart for it's power supply. However, the D1 with the external Sbooster Power Supply upgrade does sound significantly better because it is a linear mode toroidal AC to DC power supply. Many people have stated the D1 with the Sbooster upgrade, is very close in sound quality to the Lumin T1 which has a MSRP of $4000.
    - It is well known that DC power is cleaner and quieter when compared to AC, especially if compared to a "switch mode" AC power supply as in the D2.
    - Full size (D2) vs. mid-size/compact size (D1). Enlarged cabinet/board casing on D2.
    - D2 supports DSD128 5.6MHz audio format and playback of all music file types (from the change in CPU).
    - D1 supports DSD64 2.8MHz audio format and playback of all music file types
    - Outputs and other connections on the rear panel are the same for the D1 and D2
    - both Silver and Black color available in D2 to match consumer preference, D1 is shipped in a silver finish only
    - IEC power cord socket used for the internal "switch mode" power supply found in the D2. Power cord included is for internal/external AC use only.
    - The Lumin Application and streaming services support, are exactly the same for D1 and D2.
    - D1 and D2 use the same DACs (Wolfson WM8741).
    - MSRP D1 with wall wart: $2000, with Sbooster external linear mode toroidal power supply upgrade: $2375
    - MSRP D2 with internal "100/240 switching mode" (consumer grade) AC power supply: $2300

    The D2 internal power supply is different from the one inside the M1, because the latter needs a lot more power for the amplifier.

    Note that we only have a few units of D1 remaining for purchase.

    Re: Lumin D2

    I have had the new D2 for a couple of weeks and really love it. I have XLR's running to my Pass XP-30 and the Power Cable is plugged into a PurePower 2000 which I would never want to be without.
    This week I will be getting a BNC to RCA digital cable to plug into my K-01X and be able to see if that makes an even bigger improvement using Tidal through the Lumin. I will still have to play the MQA's through the XLR's but I am hoping the other CD quality will sound even better through the Esoteric. - ALL FUN

    MQA is a step up in quality and I was surprised to see so much available. Lumin is easy to set up based on the fact that I could do it and it worked on the first attempt. It also looks great in the rack. There is a Masters' List and also the album is marked MQA with a symbol when you look a CD up by artist. Very nice setup

    If you use the Lumin D2 digital output, you can set the MQA mode to Digital Output. This will do the MQA Core decoding (first unfold) to 88.2kHz or 96kHz to BNC-SPDIF. (Note that analog outputs will be muted when playing MQA this way.)

    That is fantastic advice. I had no idea. My cable comes in this week so I am excited.

    Re: Lumin D2

    the D2 is certainly an elegant, one-box solution for computer audio... has me very interested.

    anyone have any thoughts on how it (or the D1 predecessor) sounds versus the ps audio DS junior and/or the auralic altair -- two other similar dac/streamers in the mix for me?

    thanks!

    The D2 is a nice step up from the D1. I sold one to HK, hopefully he will chime in with his thoughts.

    Re: Lumin D2

    Two users of Lumin D2 reported XLR output sounds better (which is expected because of Lumin true balanced design) - that is even true with one of them using an integrated amp that does not use a true balanced design, but internally converts balanced to single ended.

    I have both the Lumin and the PS Audio Junior. I have the Lumin cabled with XLR to the Pass XP 30 Preamp and also Digital Cable to the Esoteric K-01-X and it sounds great either way.
    The PS Audio Junior, in my den system, was far superior to the DAC in my integrated McIntosh and each free upgrade has moved it to an even higher level.
    The Junior is a substantial piece of equipment and the Lumin is adorable. Either choice is a good one.

    experienced this exact thing a few months ago. it turned out to be nothing related to hardware or any associated playback software... for some reason after an operating system update i was logged out of a streaming service. after logging back in all was good again... so, might give that a check for tidal at the place where you log-in -- lumin app, roon, etc.

    Please logout your Tidal account from all devices (if any) that is not Lumin, and computer.

    Then use Lumin app to logout from Tidal, then re-login.

    Re: Lumin D2

    What is the D2's sound character like? Does it come off fairly neutral or more warm or polite? I'd like to find a one box solution to get started with, is the D2 easy enough to set up and use?

    If memory serves when I was comparing the D2 and Altair, the D2 doesn't stream wireless in the way the Altair does. If so, is there a work around like an extender and Ethernet attachment, I forget what it's called?

    Re: Lumin D2

    For sound character (warm) and ease of use I'll leave that to other users to comment on, or you may check out the various D1 reviews - there are D2 reviews but they are not in English.

    For WiFi to Ethernet conversion, you may use a WiFi to Ethernet adapter, or known as wireless bridge. Some (not all) WiFi routers can be configured to operate in WiFi Client mode that performs a similar function (but with usually better hardware).

    You need an iPad to use Lumin.

    While waiting for others to chime in, I google translated a D2 review from https://www.hifi.nl/artikel/26454/Re...nde-klank.html , it says this:
    The Lumin D2 also has a neutral sound with a very light touch of warmth. Dynamics and spaciousness are in good hands with the Lumin D2.
    For the setup, the main thing is to get MinimServer running on a computer or NAS - with some NAS it can be installed without too much difficulty and is actually easier than what the lengthy description seems to imply, and set your music library path correctly:
    http://minimserver.com/installing.html

    With the iPad connected to the WiFi router of your network, the Lumin app should see the MinimServer and let you choose albums and add them to playlist.

    Re: Lumin D2

    I don't suspect anyone but a dealer would have made the comparison and I doubt they are going to say anything that isn't positive of either combo. If you own and are happy with the D1+Sbooster why would you have a reason to just spend the money to try the other option.

    Lumin cannot endorse any internal component change.

    Any unit shipped back for repair must contain the original components with no hardware modification (including the drive in L1).

    Re: Lumin D2

    I got a D2 the other day from Mike and I'm really impressed with everything from the packaging to the build quality to the ease of use to the sound. I didn't expect it to be this good. I figured it would primarily be a streamer with the DAC as an afterthought, not at all!

    Re: Lumin D2

    I powered on my Lumin D2 this morning and there is only a Circle icon on the display. No other information and the Lumin app no longer sees the D2, but can see my U1. Anybody have a clue about how to regain access to the D2?

    Re: Lumin D2

    Please power down your Lumin units, iPad, and all network switches/AP. Power cycle the WiFi router, then the switches/AP. Wait for 5 minutes, then power up both Lumin and the iPad.

    When there is no playlist, only a circle appears on the front panel.

    Re: Lumin D2

    Roon forum member posted his impressions of Lumin D2 in https://community.roonlabs.com/t/dsd...568/16?u=wklie
    I genuinely cried during the first track I listened to…for me it really was that good at conveying the music. Vocals and instruments all seem to just sound more present, 3 dimensional and organic, drums and guitar in particular sound as I believe they should. The background against which they appear also seems somehow darker and more silent. The rest of my system, which lusts longingly for a future upgrade to Amphion speakers and a Hegel amp, has no business sounding this good. My headphones, connected via the balanced outputs to an Arcam rHead, also sound completely upgraded. I’ll make a decision over the weekend after some more hard-headed comparison but at this point I’d be very surprised if I don’t choose to keep it.

    Re: Lumin D2

    I just received my Lumin D2 today. I know it must be "pilot error", but I have been unable to get it to play any tracks. I have a subscription to TIDAL and I can bring up all my music there, but when I click on the "play" button in the Lumin IPad app, nothing happens. Same thing for playing the music that showed up in the Lumin App when I first connected to the D2. I can see the music in the app, I can switch from one song to another on the app, but the play button is not functional. Also, if I airplay Tidal from my Ipad, it will not play. It shows it is connected to the Lumin, but no sound. In all cases, I see the song listed on the front window of the Lumin, and a circle, but it never shows it playing. It's got to be in my settings, but I cannot figure it out. My Lumin is connected directly to my McIntosh MA252 and to the my home network. Everything seems to work fine except the "play" button is non functioning. I would appreciate any help that could be provided.

    Re: Lumin D2

    Try turning the Lumin and the iPad completely off wait a couple of minutes then turn them back on Lumin first. If that doesn't work try logging out of Tidal and back in inside the Lumin app.
