    If U1 Volume Control is ON - U1 will convert DSD to PCM, because we cannot manipulate volume for DSD.

    I tested U1 USB output to Esoteric N-05 USB input, with Volume Control ON and OFF, with CD and SACD (DSD64) versions of the same album, and a DSD128 music. In all tests I've done I've verified that left/right channels are correct as compared to Esoteric N-05 network input, as well as CD compared to SACD. The volume of CD vs SACD, from U1 with Volume Control OFF, is exactly the same from N-05 balanced output.
    Many thanks, wklie, for your quick reply. Have been out of town in the past few days and could only check the firmware of my U1 today. It is indeed the 7.09 version. In the circumstances, I shall get hold of another DAC to see if the Holo Spring and U1 is a mismatch.

    Re: Lumin U1

    Usually the Firmware Release Notes page is shown when Lumin app prompts for a new firmware and the user chooses to view it.

    I don't think it's accessible from the web support page. I'll discuss with related personnel and see whether this should be added. Thanks.

    In case anybody experiences similar DSD left / right channel reverse problem, here is ppnuts' solution from hiendy forum dated 2017-1-17:

    Just like to report that I have 'downgraded' my SingXer SU-1's firmware from ver2.02 to 2.00 without any hustle. DSDs through the Holo Spring now have their channels put right, i.e. left is left and right is right. Thanks to contributors here, especially clplarry. What remains on my wish list now is Jeff of Holo Spring releasing a firmware update boosting by 6db the output level of DSD files played thru his brainchild.

    I would also like to share my experience in enhancing the sound quality of the Singxer plus Holo in a system involving the use of a streamer:

    1. Cat. 7 ethernet cables must be used. This gives audible improvement in removing 'edginess' in the music.

    2. Connect your music streamer and NAS to a switch and then to your router. This seems to be against the law of physics not to connect them directly to the router. But it must be heard to believe. With a Zyxel switch sitting between my streamer plus NAS and the router, every musical note becomes sharply focused, and the background stage definitely gets darker.

    3. Where possible, replace the stock power supply of the switch and NAS with an LPS (linear power supply). Improvements obtained under 2 above are further enhanced.

    Re: Lumin U1

    Hello
    I recently bought a Lumin U1 , and used the Analysis plus Oval cable in AES EBU , to be connected to the Chord DAVE
    Music is stored in a Melco N1A
    The Lumin U1 is connected to the Melco via RJ45
    I have in my set up
    Auralic Aries femto one
    Aurender N100 H

    Well , the U1 does offer jaw breaking music
    It has been running continuously for about 24 hrs now .
    Firmware has been updated to the latest one

    One question : is the PSU , the newly designed one , coming with the S1 (reviewed on 6 moons I think ? )
    I have read some pages (here and elsewhere) about Kenneth Lu PSU for Lumin
    What is the manufacturer's point of view ?
    I read that Peter didn't test the Kenneth Lau PSU ..but is it a real upgrade or just a hifi geek perception (LOL)

    Cheers

    Re: Lumin U1

    Hello
    2 thoughts about the Lumin U1
    1. I have connected the Melco N1A to the Lumin directly , and listened to music , the ipad using the Lumin app
    2. Then I installed ROON on a CAPS server , LPS powered , Roon has been configured to Watch the "share" folder on the Melco .. Roon app to send music

    Well , Roon doesn't deliver as clear music as the Melco+ Lumin alone .. is it expected ? Is it weird

    Another thought : Is it interesting to use a balanced conditioner for mains , to yield to soem extra , better sound from the Lumin and Melco ?

    Thanks

    Re: Lumin U1

    Yes, U1 will output Native DSD when connected to most XMOS-based USB Native DSD DAC, Esoteric K-0*x, and for those USB DAC supported by the xmos-native-dsd project, excluding those that use the Amanero USB module.

    Does the Lumin U1 110v power supply have have the option to change to 230v? Or do you have to get a different power supply? Can you use the same U1?

    Lumin external 110V and 220V power supplies for U1 / S1 / A1 / T1 do not have a switch to select voltage - they use different components.

    Lumin U1 and X1 Firmware 11 now support playback of DSD256 music to Chord DAVE via USB using DoP256 format. Since we don't actually have a Chord DAC to test with, feedback is much appreciated.

    Zaheer - NativeDSD is a solid source for DSD downloads. You can easily see which resolutions they have available for each selection. Acoustic Sounds also has some good titles available.

    Re: Lumin U1

    I have been using my Lumin U1 connected via USB to a PS Audio DirectStream DAC without a problem. This morning I decided I wanted to try using the Lumin U1 with the PS Audio DAC's AES/EBU connection using a Transparent Reference Digital XLR cable. The DAC doesn't recognize the Lumin on this connection (icon on the DAC is RED). If I use the same digital cable with an Aurender N10 to the AES/EBU port on the PS Audio DAC it works perfectly. Going back to the USB cable on the U1 also works perfectly. Any hints on what I can do to use the Lumin's AES/EBU output to the PS Audio DAC?

    Re: Lumin U1

    In Lumin app:
    - Please make sure Re-Sampling is OFF, not Custom.
    - Please use Lumin app to turn the AES output OFF, then ON.

    If it still does not work, please try RCA (regular SPDIF) output and see if it works or not.

    Re: Lumin U1

    Thanks audio.bill, this archive shows Lumin U1 was previously certified compatible by Chord:

    Comparing this archived web page with the current web page, not only Lumin U1 is removed, but HQPlayer and Hysolid are removed as well. I guess I can understand why Lumin U1 is removed, but I'm a little surprised even some software is removed. The Hysolid "Turn your PC into a network player" software, and HQPlayer too - perhaps the latter coincided the functionality of Hugo M Scaler?

    Re: Lumin U1

    Is it OK to connect the Lumin U1 USB output and the AES/EBU connection at the same time to a DAC? I want to do A/B testing to see which sounds better. Can I leave them connected for an extended time without negative repercussions?

    Re: Lumin U1

    For A/B testing, it is best to disconnect USB if a non-USB connection is to be evaluated for SQ. Depends on the DAC hardware, the presence of a USB connection (even if not used) can potentially negatively affect the SQ of a non-USB input of the DAC.

    For a short duration, simultaneous connection of the U1 (MINI) USB output and one or more non-USB outputs may not result in abnormal playback. If a USB output is connected it becomes the primary output and is usually asynchronous. The non-USB outputs are synchronous. For an extended time the playback to non-USB outputs may not be correct due to timing differences from USB.

    If USB output is not used, all four non-USB outputs of U1 (MINI) can be simultaneously connected.

    Re: Lumin U1

    When trying to set up a new to me U1 I get "Network Error" on the screen and the U1 is not seen by the Lumin iPad app nor by Roon. The U1 is connected by ethernet to a local switch then to a router.
    My music files are on a Qnap NAS running minim-server that I just installed. The Lumin app and the minim-server communicated and loaded all my music to the app. Is there a reset process for the U1?

    I just finished power cycling everything in the network from the modem, router, switch and U1 as well as swapping ethernet cables and ports on the local switch including known working ethernet ports and wires and still get "network error" on the screen. Tried unplugging the U1 Power supply and switching the usb connection to the dac on the U1 from usb1 to usb2.
    Any help appreciated.

    Re: Lumin U1

    Ok, the Lumin U1 is working now!

    I ran a 25 foot ethernet cable from another switch in another room to the U1 and it works fine so there is something going on with the switch at my audio rack. Interestingly, before I did that I did put the Lumin U1 in the place of another working device at my audio rack switch (my dac) using it's working ethernet cable and the Lumin was still not working.
