DSD and MQA playback on ifi Zen One Signature DAC


Am using ifi Zen One Signature as my main DAC connected to my windows 11 pro pc. In Audirvana Origin the Dac is not able to play DSD as native but it is doing DSD over PCM 1.0/1.1 and is limited to 64 and 128 but not 256, though my dac has native DSD256 capabilities.

Also when I set the output as ASIO the DSD is turned off on Native and MQA is not being detected.

If I select as Kernel Streaming then the MQA is being detected as a Decoder. But DSD Native is still not there.

Only if I select it as DSD over PCM 1.0/1.1 then only DSD 64 and 128 is turning on. I know DSD over PCM gets half of what the device’s max DSD bit support.

Also my debug log here:

Please let me know how I can solve this issue.

Did you install the ASIO driver?

The PCM carrier sample-rate for DoP transmission of DSD256 is 705.6kHz… the iFi DAC supports up to 384kHz or the PCM carrier sample-rate of 352.6kHz for DoP transmission of DSD128
:notes: :eye: :headphones: :eye: :notes:

The ZEN One Signature is the first ZEN DAC to support all hi-res: DSD256, PCM384, MQA384kHz, Bluetooth 96KHz.

Unit looks to be capable, I’m going with @bitracer he doesn’t have all the driver’s or firmware updates.

He should Goto iFi site and get the full package for his DAC

In the context of DoP… the PCM sample-rate of 384kHz is the limiting factor…

He’s on windows, isn’t there a driver that can do dsd 256 on windows? I think that’s what racer is trying to achieve for him. I could be completely wrong, I’m allergic to Microsoft

This why I focused on the DoP limitation… I understand Windows drivers will allow native raw DSDxxx transmission…

Yes I did

I did a full uninstallation and reinstallation of the Driver v5.12 and guess what… the DSD is back and I can play DSD256 on Native. Zen One is displaying Red LED indicator for the DSD256.

But still no auto detection of MQA… I can select it as MQA decoder manually. Don’t know if that will work.

Bingo, set your MQA manually should work. For some reason iFi gear is really dependent upon downloading the most recent firmware and drivers. I’m thinking with windows especially.

Thanks I will try that out.

Hi @satyajit the MQA auto detection will not work on ASIO, you need to set it up manually as the MQA auto detection is made for WASAPI :wink:

Oh thanks a lot…

By doing it manually will the MQA still work in ASIO mode?

Yes it is, you will see your device LED will change for the MQA color when starting playback.
