Question about Lumin T2 playback

I did burn-in my Lumin 24/7 for 4 weeks now. I have a Marantz SR7013 as an AVR but when I choose DSD128 I don’t hear any difference. Am I doing something wrong ore do I need to hook my Lumin with USB to a PC. I have Roon Rock on my NUC.

Are you streaming DSD over ethernet to the Lumin?
How’s your Lumin connected to the AVR?

Yes I am streaming over ethernet. The Lumin is connected with RCA cable to AVR

The AVR has no XLR input

Then you should be all set then, regarding connections.
I guess you’ve checked your Roon signal path so that the Lumin actually outputs DSD?
Maybe your AVR digitize the analogue signal and thus in some way degrading it?
Is there a “bypass” function on the AVR to keep the signal in the analogue domain, perhaps try to engage that?

The Marantz has no Bypass function. Maybe I should try pure direct mode on the AVR. It is now set to direct mode so I have Stereo sound and I can use bass and treble.

Yes, If you’re applying bass management or any other DSP, the AVR probably has to convert the incoming audio into PCM.

In pure direct mode it sounds terrible
