Thank you for the information.

By the way, are you currently using the D30 Pro?
Can PCM384kHz be played normally?
Please let me know the current situation.
PCM384kHz works fine on both D30Pro I currently have in my rigs, one still has the v2.44 as it came out of the box, and the second was recently updated to v2.46.
No issues.

Thank you for your valuable information.
I've posted the same question twice in the past and never got an answer.
So I completely gave up on purchasing the D30Pro again.

Sorry for the delay you experienced.
I got my second D30Pro from a colleague who was unable to manage the spdif-coax issue with his cd transports, and this gave me a lot of occasions to test it as a "shuttle" dac between my rigs, with the advantage of being well acquainted with its "sound".
I'm happy with these two bad boys.

While waiting for the D30 Pro to arrive, how can I check which firmware version is installed on the device?

Thank you very much for your valuable help

Linux: lsusb -v and look for bcdDevice under Your device. Probably better way is to grep it, but im a noob.

Thanks! Any other method that does not require connecting the DAC to a PC?

i noticed 2.46 wakes up longer (up to two seconds) from standby, but no reliable way that i know of.

I hope my copy has the latest version installed. Thanks for the tip.

Using the D30 pro with firmware V2.44 without a single problem for over 18 months now.
I don't see any reason to upgrade to V2.46 even more because it is unknown what it suppose to improve/change.

Don't try to fix something that is not broken..

My new combo is here. Topping D30 Pro and A30 Pro. Unfortunately, D30 Pro is defective. Although everything seems OK, screen on, source correctly identified, configuration steps run well… there isn’t any sound out of RCA outputs. No matter which output mode (Pre or DAC) or output channel (RCA or RCA + XLR) I choose. Thanks to my reliable Fiio K5 Pro i‘ve been able to test both units and identify the culprit.
I opened a support ticket wuth the seller. Until the new unit arrives, I am testing the A30 Po with the K5 Pro as DAC.

okay so with 2.44 doesn't it wake display to show change in sample freq.? because it does not do that on 2.46 – on this firmware it only show sample change if display is already woke up (showing volume value, not only circled USB notifier)

Neither with 2.44 nor with 2.46.
Never saw the display lit on from L4 status to inform about the sample frequecy change.
Hope I've understood what you mean.

The A30Pro and D30Pro seem to be a good combination. Actually i use the Smsl D6 & SH9. I am very interested in the D30 Pro because of its power. Is it better to change the DAC, too to have everything from one brand or is the D30Pro not necessary and the A30Pro alone makes more sense?

I have the D/A 30 pro stack which I’m very happy with.

The D30 replacement unit has arrived. I have tested it via the USB and optical inputs, the latter connected to a Samsung TV with no sound loss or disconnection. Good match between the D30 and the A30.
