If you have roon set to equalize volume or using DSP volume control it might be attenuating the volume by -6db. Try turning it off. It might be the Lumin as well I tried a U1 mini and it would adjust volume in DSP need to change a setting can’t remember how I turned it off.
To Roon or not
For the past few years I have been using a LuminT2 w/ Qobuz and it's copacetic.
Happy with the sound. Ok with the software. Not happy with having to pull up a browser to search for information about the artists or have similar music/artists be at the ready to explore.
Back when Roon didn’t work with Qobuz. Now it does.
In my testing I think the native Lumin software sounds better (fuller, richer) that when using Roon.
A few questions please. I’m looking for secret sauce settings.
Are there MQA setting(s) that I might be better off using? Currently set to “render only.”
Use the Roon DSP?
Sample Rate Conversion Settings?
I’m using an iPad that sees the Roon core on a computer else where in the house. If I can't tell any sound difference then an old computer can serve as the core. The iPad also runs my Amp/Lumin with split view and that's great. For some reason Roon will not work with split view?
