Is it normal that there is a soft ground hiss that does not get louder or quieter when i change the volume. Its the same whit all iems or headphones. Bluetooth or wired. Am1 am3e and am3d

Depends on your headphones/IEM. My 4 ohm Wraith hiss really loud on AM3D even when playing music. On the AM3E, it's much less but can still hear it when music isn't playing. This is regardless of source (BT or DAC). The noise is from the amp modules. I suspect anything over 16 ohms should silent on AM3E. Not sure about AM3D.

Thank god I don't have any interest in IEMs. I would really not enjoy all the matching issues and after reading many, many posts from IEM users over the years, matching issues are extremely common.

Why is FiIO firmware only available from shady back allies on the Internet?

The official word from the Fiio rep on the thread is that the firmware update has not been released yet. Downloading any unofficial firmware package from unofficial sources is highly risky. When the official firmware is released and available on the Fiio website, I'm sure we will hear about it. If you look at all of the other Fiio official firmware announcements, it's very obvious on Headfi and their website. There is absolutely zero backdoor ways of getting official production firmware from Fiio.

Seriously, why on earth would anybody take such a risk? What major problem is so dire that a firmware update just has to happen outside of the official channels? I think the Q5s is already a very stable (if imperfect) product.

I have a Valkyrie and have been looking for a BT dac, it's interesting to hear that the Q5S isn't completely silent, BTR3 is alright but tanks out at higher volume level, lots distortion and isn't completely hiss free. The only portable option that has a black background and no distortion, so far, has been the Apple dongle.

Per spec Valkyrie is less sensitive than Wraith but has lower input impedance so you will likely hear background hiss. However we are talking 3 or 4 ohm input impedance so not sure if any DAC or amp is going to be completely silent. My WM1z with Ultimate K-Mod is nearly silent, but there is "something" that I don't hear when I unplug.

Oh no! My DAC got hacked! You guys watch too much TV.

No, your PC got hacked when you downloaded the fw file and unpacked it. Or you bricked your DAC trying to update a corrupted bin file.

Quite right. However, the insinuation was because the provider of the unofficial firmware was from Russia, therefore....
If Fiio provide verifiable downloads of firmware (SHA/MD5 hash) that would be great. Oh, wait. They don't.

Anyone tried the Q5s with Focal elegia? Does this pairing sound good?

That is more of a practice of open source code which Fiio is not. Name one DAC or DAP vendor that allows open distribution of their firmware and provides hash values to confirm source. Stop picking on Fiio. Waiting until production release directly form their support website is secure enough.

I'm not picking on Fiio. Just showing that generally insecurity of distributed software is not a geographical problem.

Is it?
