Just got an Airlens to replace my matrix SPDIF II. My Airlens is connected via I2S to Direcstream MKI - BHK Preamp- McIntosh amp. I have a NUK (with all my music).. All running thru ROON.
I have updated both the firmwares.
I can play music dsd256, from ROOn ,into airlens and into my Directstream, and it will show dsd64.
My device setup for airlens in ROON is: MQA capabilities: No MQA support; Vol Control: fixed; Max sample rate:up to 384kHz; Max bits: 32; Max sample rate (DSD); up to DSD256. Clock master: default; Enable MQA core decoder: No;
My device setup for Directstream in ROON is:
MQA capabilities: No MQA support; Vol control: Device Vol; Max sample rate (PCM): up to 192kHz; Max bits per sample (PCM): 24; .
Clock master: Default; Enable MQA: No; Im using in ROON my direcstream as the player.
Any help will be greatly appreciated. Thanks,
Send a screenshot of your Signal Path when playing DSD256. It might provide an answer. I likely can’t provide it but someone else might! Good luck

Roon appears to be doing this, not AirLens
found this from 2019 (about 5 years before AirLens release)…Please explain sigma-delta modulator in my signal path - Roon Software Discussion - Roon Labs Community
Interesting you found it 5 yrs before Airlens, But How do you fix it.??
No idea, sorry
Underneath Airlens what do pins 3 and 4 look like - both should be ON for DSD 256, you might need to check pin 5 for native vs DOP also
Does your MK1 have the Bridge card installed and if so is it still connected somehow? Try removing and re-adding any and all audio zones in Roon.
All the pins are up on the Airlens. I have not removed the bridge card on the MKI yet, to try .
