Lumin U2 mini released

No, I would not describe it this way.

Upsampling settings are provided for users to experiment with, in case they find a setting they prefer to native. When using Roon, Lumin upsampling should be disabled as you can do more sophisticated upsampling with Roon DSP Engine.

Thank you so much Peter.
You are always very helpful.
I guess I will sell TT2 or something and just stick with NOS DACs to see which setting I prefer between upsample enabled and disabled.
Thank you! :slight_smile:

I just ordered my U2 mini. I am excited to hear the difference of the USB connection into my Holo Audio May KTE DAC. From what I have read the USB interface on this DAC is superb. The U2 mini will be replacing a D2 that I have only ever been using as a streamer. The D2 used a coax cable into the May DAC because it does not have a USB out… Should be an interesting test to see what I can hear.

Some research on the Chord website could be helpful for your edification.

@wklie Is it normal for the volume control in the Lumin iPhone app to disable DSD sample rates higher than DSD128?

When I enable volume control in the Lumin app I am limited to DSD128 and if I disable it I can select up to DSD512. Here is a screen shot of the Lumin setting I am referring to.

Here is a screen shot of the Roon interface when the volume control is set to “On” in the lumin app:

And here is a screen shot of the Roon interface when the volume control is set to “Off” in the Lumin app:

In Lumin product line:

  • Only Lumin product analog output can do DSD with volume control

  • Digital output supports DSD only if volume control is disabled. If you need Lumin volume control for digital output, please use Roon DSP Engine to convert DSD to PCM first.
