One question, the analogue output, how come it works according to the volume of the headphone amp and isn't it fixed? Is there any way to make it fixed?

it’s controled by the K5 volume, as in a preamp. No way to make it fixed.

Dear friend,

The headphones out and line out can work at the same time, and the amplitude can be adjusted. However, the line out output is up to 2Vrms. It is possible to connect an integrated amplifier or an active speaker, but it is not enough to use with the pure power stage amplifier as the preamp.

Best regards

I only use IEM and was worried about the hiss with the K5 PRO but with the help of Brava210 who tries his IEM and told me that all was fine I buyed mine.

On wednesday 27/1 arrived my Fioo K5 pro. I´m very happy with it. I´ve tried: KZ ZS 10 PRO, NICEHCK M6, AUDIOSENSE T800 and TRI-I3 and all sound nice with a great improvement with some of them.

Yesterday I started to play with it and i find an strange behaviour. If I use the usb input all is fine, but if I use he SPDIF IN (or no input connected) I can hear huge hiss with the TRI-I3, if I touch the metal box of the K5 the hiss dissapear but if I left to touch it then again huge hiss. No matter if he Fioo is ON or OFF I can hear the hiss until I keep touched it or conected to and usb source. I´ve tried several plugs of my house and 3 protected strips.

Any help? Is this behaviour usual or got a faulty unit?

I have used this amp for 7 months. Everything is fine. Just few days ago the unit start to turn on and off and disconnect from the PC in usb DAC amp mode. Even though the unit light up while turned on, it seems to fail to to establish connection to the PC via usb. Seems the USB dac circuit has fried. Guys wanting to buy this DAC amp should be aware from this issue.

are you sure it's not the rubbish cable that comes with the Amp?
I bought a much better one from Amazon

Dear friend,

Sorry to hear about that. Does the other input mode work fine instead? If yes, can you find another usb adapter to check whether the issue remains?

Dear friend,

Does the indicator show red all the time when using USB mode? It seems to be a hardware issue with your K5pro. You could try to contact the seller to see whether he could help first. If not, please contact us again via support@fiio.com

Best regards

Hello Everyone.
What are the 2 most important features you would need if the K5 Pro were to be upgraded?

The most important improvement would be that it could play 24bit/96khz files in through the optical input from my Chromecast Audio, which it does not despite the specifications.

I have a big problem with my K5 Pro.

It will not play hi res 24bit/96khz PCM files fed to it through the optical input from my Chromecast Audio. The K5's light glows green but no audio is produced. My dealer replaced the unit but it still has this issue. This is a big disappointment for me because most of my files are 24/96 and I want to use the K5 Pro with the CCA.

Could you try it with another DAC? Just to be sure the problem lies in the K5 Pro

Yes I did try the same files, optical cable and CCA into my main system DAC (Maverick Tubedac Plus) and it played no problem.

Hello ，Sorry to touble you
Under normal circumstances, the K5 Pro's optical input is capable of supporting up to 96k 24bit.
Wouldn't it be better to replace the second end of the fiber optic cable?

Yes, I could purchase a different streamer such as Raspberry Pi, or buy a different DAC and just use the K5 Pro as a headphone amp. I hoped to avoid spending more on this solution though, given I have two extra ChromeCast audios to use. I guess there is no solution that doesn't involve more $$$
