Enjoy :confetti_ball::balloon::tada::sparkles::sunny:

Is there any reason to use this since Roon can already do the decoding and the Lyngdorf does not render anyway? I get why it might matter without Roon.

TDAI can decode up to 384Khz. Roon does only the first un-fold up to 96kHz.
However, as far as I know, no redender is applied in TDAI 3400.

I don’t think that is true. It seems the Lyngdorf does the first unfold only, same as Roon. This is from the specs list on their website:

Mediaplayer: Roon Ready, Spotify Connect, Tidal Connect, DLNA Support (uPnP), Airplay, Local file playback (USB), Internet Radio (vTuner), MQA Core Decoder (output is 88.2kHz or 96kHz)

Actually I just tried with a 192khz MQA album on Tidal. If I decode in Roon it only goes to 96khz but if I set the Lyngdorf as a decoder/renderer Roon shows it as a full decode to 192khz. It still downsamples to 96khz for RoomPerfect but that’s at least some difference. In the signal path in Roon it indicates that the Lyngdorf is doing full MQA decoding and rendering but I don’t believe that’s true.

That means as I suggested that Lyngdorf does more than the first unfold. Re-creation og higher sampling than 96 khz requires more than the first unfold, as this only gives 96 Khz. But there is no filter redering applied. Not possible in a full digital architecture.

Is it showing that it decoded it or is it just showing what the original sample rate would be if it could decode it?

It’s fully decoded to 192khz.
