Needless to say, other devices I had, on day one, also had Mqa rendering and decoding problems as well as other distortion problems. The seriousness of FiiO will be evaluated for how they will be able to solve problems as they arise because no device is free from problems. FiiO puts much of its future credibility on the K9 Pro and I hope they put a lot of effort into that

We will update the MQA-related issues as soon as possible, but in a responsible manner, our updated firmware must have undergone extensive testing, so it will take a little longer

Thank you very much for your support!

Still trying to love this thing, as i like the idea of replacing everything on my desk except the LD MK3 with it a lot. But i increasingly tend to think that something is indeed wrong with the one i received. I A/B-ed a bit with the C3R and the sound partly seems to be downright unbalanced and off, for example male vocals on my K9 Pro tend to sound recessed and veiled. Also, trailing ends seem to be very much compressed. This can't be normal, can it?

Forgive me, but I do not find anything you say, quite the opposite and I come from R2R, GSX-mini, Meze, etc...

I thought so, maybe asking for a repair/replacement is the way to go.

I just received my K9 Pro and have been using it for 2 days.

When using it on Pre-out mode which is one of the reasons I got it it has the volume go up and down randomly on its own while playing. I believe a few people in this thread are having the same issues. It does not matter how I set the switches on the front panel it keeps having this issue.

Also when I install the driver from Fiio's website Windows shows it as a Fiio Q device. Is this correct? When I first connected it Windows showed it as a Fiio K9 Pro. Did I use the wrong driver?

The last issue is if I use it in DAC mode Tidal (in exclusive mode) it will not let me control the volume from windows. I had my speakers at max volume and hit play with windows volume at 4 and I almost blew my speakers.

I have sent the above to Fiio support and waiting to hear back from them.

I am really worried I have a bad unit.

why are your speakers at max volume.....

 

[Psylocke]

The speakers I have can be set to max volume and controlled by the pre amp or by windows depending on how it is setup. They are a pain to adjust the volume with as the main volume control. Terrible remote control and hub design. Amazing sound though so work around make it better.

what a conincidence....I have the Paradigm millieniaone CT for my desk and do agree that the remote is a pos.

the workaround can be dangerous as you have found. it's generally not a good idea to max out the speakers, and max out the source as you probably know.

generally tidal exclusive mode will force max volume in order to prevent resampling. volume is then controlled on your preamp

 

[Psylocke]

That is a coincidence. Mine are the CT 2.

When you use the K9 IN DAC mode the volume has to be controlled either from the speakers or windows. I use to have the Audioquest Cobalt day as my source and had the speakers set to around 60 and controlled sound level through windows. Worked flawlessly even with Tidal.

I hope I did not damage my CT 2s.

cobalt doesn't have a physical volume control so their driver allows for volume control given it has a headphone amp output

Not sure about K9 if the signal goes through the preamp before going to line out, or if the line out skips the preamp completely as is generally the intent of a dac

The older driver shows FiiO Q device. The beta version on the same page correctly identifies it as a FiiO K9 Pro.

 

[Psylocke]

I will give the beta driver a try.

I had a chance to listen to it with my AC setup.
phone (Tidal) -> USB,
RCA -> AMP,
AMP -> AC

MQA works
no problem with volume.

But I am listening on DAC output, not Pre. Cause I do not have "pre" input on my AMP, only line.

So looks like a problem only with "Pre" output.

I Will think about buying second one on ES9038 to compare

Absolutely not. The MQA rendering issue is on dac, amp and preamp mode, the issue is only from MQA to MQA files. It depends on the format. Very soon will be available a firmware update that solves
