Thanks for your input, John57. I was also looking at JRiver as an option, but haven't tried it out yet. It was weird, on top of the scanning issue, activating the eq on Colibri also caused the same freeze/no audio issue.

There is a bug in the mobile app. It is showing FW v1.0, but there is v1.13 in the device.

I do not agree that it is fine to have limited possibility to upgrade the firmware. Just there will be no sound improvement in the new firmware and I do not observe any of the problems described on this forum.

There are other serious design flaws that Fiio do not want solve. For example the equalizer works only for bluetooth, it is not mentioned in any official document. The intensity and pattern of the status indicator is not persistent, it resets to default when power source is turned off.

You are correct, and I just confirmed my FW is 1.13 via computer (should've checked this way in the first place, but also want to believe in Fiio's apps/tools but seem to be a bit buggy. Thank you for your input!

Activating EQ on a DSD file will never work unless it is converted to PCM first and back to DSD. Are you playing DSD files natively?

Aaaaand I just ordered me a K9 Pro. It has been several years since I invested in either a DAC or amp. I will be comparing it to my Schiit Jotunheim v1.

Just received my K9 Pro, and wanted to upgrade my firmware but came across a glaring issue: I am on Mac with no windows machine available (as I suspect is the case for a good portion of customers)...There appears to be no Mac OS support for upgrading the firmware? I attempted firmware upgrade via Fiio Control Android app with "local upgrade" option, selecting the upgrade file from my phone, and that always fails. The "online upgrade" is ideal, but currently when I tap that option, a pop-up message displays "not support yet". I would like to know if there is future "online upgrade" capabilities being planned, or Mac OS firmware upgrade support. Any reason the "local upgrade" option fails every time? Thank you in advance.

Dear friend,

The 1.0 version you check from the APP is the Bluetooth firmware version for the K9Pro. And there is no new Bluetooth firmware for the K9Pro.

The 1.13 version which could be checked from the computer or the firmware update tool is the system firmware version. Since the chip supplier could not provide the update tool for MAC to us currently, the system firmware could only be updated in Windows computer, sorry.

In the FAQ of K9Pro, we have mentioned the EQ is only valid for Bluetooth: https://www.fiio.com/newsinfo/557553.html

Our USB DAC could not support the EQ adjustment in USB DAC mode now.

Best regards

Some thoughts direct from FiiO about the different DACs

This plastic shield could keep the structure more stable.

Does the K9 Pro ESS also have a plastic shield?

Finally bought akm

How bad are the Bluetooth issues? Are they a dealbreaker?

 

[WalleyeAU]

Just got the K9 Pro AKM, running my HD650s (XLR balanced) very nicely indeed.

I was wondering, is there any quality or performance differences between using the USB B on the back or the USB C on the side (from MacBook M1 Pro)?

A lot of marketing BS.
The only difference you're going to notice is in your wallet.
