Original microRendu v1.3 DSD

[JoseL]

Hi,

Does anybody knows the maximum DSD sample rate supported by the original microRendu v1.3 (software v2.7)?

I made a search here and elsewhere but the only specifications that I have found are for the latest hardware version (v1.5).

Thanks in advance.

When I had it I was using a Mac Mini with HQP Desktop and up converting to DSD256, pretty sure DSD512 was supported.

That’s what I was thinking but with Roon it only goes up to DSD256.

As far as I can tell I have the correct settings on both the microRendu and Roon.

The signal path is:

Intel NUC/Roon ROCK> Cat 6 cable> Gb switch with SFP fiber transceiver> fiber optic cable> Sonore opticalModule> Cat 6 cable> Sonore microRendu (v1.3)> USB cable> Topping D90 DAC.

I wonder what would be the limiting factor here. Any ideas or suggestions?

Thanks again.

Are you sending Native or DoP? My DAC doesn’t support DSD512 so I can’t test for you. If it’s DoP that could be the limiting factor.

You should be able to play DSD 512 with that set up, but do note that you will have to use Native DSD and not DoP.  Also note that the D-90 DAC performs better at DSD 256 than it does at DSD 512 (this is due to how the AKM 4499 DAC chip operates, the data sheet for that chip shows that performance actually degrades with DSD 512 vs. DSD 256).
