    Re: Need help to choose the right Lumin

    Thank you very much Peter.

    To be precise:

    Does this mean that Lumin U1 Mini will automatically select USB1 output if it is the first output used to play something and will automatically shut down USB2 output? On the contrary, if I run music via USB2 first, U1 Mini will close automatically USB1 to liberate USB2?

    Or, does this mean that in the U1 Mini settings, only one USB output can be made available? Ie in order to listen to music via USB2, I have to go to the device settings and select manually the wanted USB2?

    Same question. When outputs are not simultaneously active, this means that active/unactive is handled automatically or user defined in the device settings?

    Best,

    Hey Tubes, how do you use a power supply with a device that has a power supply internally?

In other words, the D2 provides more functionality at a very modest cost.

    Specifically with respect to your two scenarios, the ND8006 and D2 sound different. So ideally you might bring your ND8006 in to a Lumin dealer to compare the DAC between the two. Or having both the ND8006 and D2, you would be able to switch back and forth as desired, and perhaps you have use for other ND8006 functionality like the CD player.
    Thank you!
    I feel that the Marantz has a better DAC (ESS Tech ES9016 à 2x4 canaux - Sabre) which is quite the same if I am not mistaken than the S1. But this is technology and the most important thing is music and emotion. To tell you the truth, I don't really make a difference between Spotify and Qobuz (tried blind tests several times). I am choosing Hi-Res as a psychological matter.

    Whether it is a better DAC I'll let you decide when you get a chance.

    Product and specification wise it's not the same as S1.

    ESS chip names are confusing in that they have a mobile line and a PRO line, which are very different architecturally and have very different chip-level prices. The mobile line can be used in a smartphone. Your DAC uses the mobile version ES9016K2M. It's not even the mobile version of 9018. Some manufacturers using mobile version DAC chips or some of their regional marketing offices often do not state the mobile designation clearly.

    S1 uses four non-mobile (i.e. PRO) chips of of 9018.

    For the USB outputs of U1 MINI, you have to make sure you only connect one USB DAC to it, not two. If a USB DAC is detected, USB output is automatically done.

    If no USB DAC is connected, the AES / BNC / coaxial / toslink outputs will be normal. This is also automatic (by the absence of USB DAC connection), although you can disable the latter outputs individually.

    Thank you for these precise answers. In fact, I am not a specialist and was confused by ESS names.

    I think I see. One cannot use 2 DACs with the U1 Mini if one of the 2 DACs is connected to U1 Mini via USB. Is my understanding correct?

    Re: Need help to choose the right Lumin

    Some other questions, Peter, thanks again for your help.

    - In Lumin U1 Mini, you think it is preferrable to use Optical or Coaxial output?
    - You confirm that in the U1 Mini the digital outputs (other than USB) can be enabled / disabled individually? I cannot see these settings in here : http://www.luminmusic.com/support-settings.html
    - In this page, regarding MQA mode : http://www.luminmusic.com/support-settings.html ; it is said that "Passthrough: LUMIN will passthrough the full MQA stream to your DAC." If my understading is correct, this sentence is misleading : the third unfold of MQA is not done if the DAC is not MQA capable?

    Thanks

    Re: Need help to choose the right Lumin

    Very important question also.
    I was always using the Lumin app on iOS to control my ND8006 (and some Sonos) enabled as openhome renderers by a Bubbleupnp server. I had problems recently with the Lumin app freezing and not recognizing the players if I don't use my iPhone or my iPad for a while. Can you please Lumin users confirm that with a Lumin renderer, you do not have this issue, ie the Lumin renderer disappearing after a while making it necessary to kill the Lumin app on iPhone or iPad and reoppening it again?

    All the best

    Peter, is it possible to send me the source of this? I cannot manage to find it on the net nor in the ND8006 specifications...

    That's ok I found it. Thanks for help

    It requires a bit of 'surgery' to remove the internal power supply and to replace it with the adapter that mounts on the back panel of the D2 and then connects to the Sbooster. It's a very simple process and well worth the effort.
