Audirvana and Audioengine HD4

Good afternoon,

I installed the trial version of Audirvana yesterday and I have a few questions. I am USB connected to a Windows Surface 6 and the Audioengine HD4 speaker system with a built in 24 bit DAC. I spent a couple of hours tinkering around last night but I don’t think I have everything set up right for sure. For example I cued up Nick Drake Five Leaves Left on Tidal MQA 96 KHZ/ 24 bit and that showed up on the left hand side of the screen. But over on the bottom right it said it was only 16 bit. What am I most likely doing wrong? Other suggested settings etc? I am just looking for the best sound with my current set up, although I will be adding a sub here soon. Like for example I did not know if I should alter the settings in the Tidal app, I typically keep it on Exclusive and leave other two adjustments unchecked.

I love the HD4 system, dead on perfect for my little den room. I am hoping Audirvana can increase that love even more. Thanks in advance.

Make sure that you’ve set “non-MQA” in the DAC settings. Click on the speaker icon in the lower right corner, select the arrow to the right of the speaker and look for the MQA settings.

Thanks. I plan on putting in more time tonight.

Something is still not right, here is my debug file. It is seeing the speakers but not the DAC in my cursory review of the data:

Are you connected to your speakers via USB?

?!? Your speakers are the DAC. It‘s built in the speakers.

Yes, I am connected via usb. Thanks

If your device is connected with USB, this then means you are limited to 16/48 unless your device need a specific driver to go above this limit.

Thank you Damien. I tested using Amazon Ultra HD and it was seeing 24 bit when it was a 24 bit source. It did lower the 96 to 48 or 44.1 during my testing but kept the 24 bit. So must be something else or a driver of some sort.

If you look in the specification it says that the max input bit depth fir USB is 24 bit padded:

It only supports 44.1 and 48 KHz sampling rates and there is no driver for it. You could do it with the normal Amazon Music subscription, you don’t need HD.
