[FIIO Q15] DAC and Headphone Amplifier Discussion & Impressions Thread

[Magnum Chaos]

Cool, my Desktop mode stopped working. I'll figure it out...

Update: I didn't notice how the logic changed in the new firmware. Switching to Desktop mode occurs when the Q15 is turned on and external power is connected. If you leave everything connected and turn it off, and then turn it on again, Q15 Desktop mode is not activated.

Video.
P.S.
I also found out that the icon on the screen "D" is the desktop mode, it disappears if you change the orientation of the screen.

Even if you turn the device on while it's off, UH mode will boot active, but the D icon isn't always visible, which is true. However, UH always boots active.

I almost beat the problems of q15. The gradual upgrade of the firmware version helped me with the firmware update. 1.82 -> 2.01 -> 2.25. Everything works stably via usb, the sound is smooth. In the case of transition from 1.82 -> 2.25, the sound is dominated by bass. I don't know why this is happening. If the latest 2.25 update is already installed and you want to update it again to fix it, it doesn't do that. For this reason, it is necessary to roll back to 1.82.

Dear friend,

Hi, thank you for the kind feedback. We will report to the engineer for checking about that first.

Best regards

Witam Mam pytanie Czy ktoś korzysta z Fiio Q15 + Campfire Audio Cascara ?
Jeżeli ktoś korzysta jakie ma ustawienie wzmocnienia (gain) do tych słuchawek.

 

[Arturw8]

Ultra Gain only. And there's no difference what headphones you are using.
Yes, cascara is sensitive but you have volume control in Fiio q15

 

[audiorob]

Witam Dziękuje za odpowiedź Zapytałem ponieważ zauważyłem że na wzmocnieniu High Gain, Super High Gain, Ultra High Gain Cascara robi się głośna Słucha się przyjemnie dopiero na wzmocnieniu medium gain Czy powinienem jednak ustawić ustawienie Ultra High Gain ?

 

[Arturw8]

When you use gain other than Ultra you only get half of your amplifier working. This is not about volume this is about quality and Headroom.
Imagine your car suddenly lost half of engine power. Even if you drive with in city speed limits you don't like it

Does higher level of gain impact sound quality?

 

[Arturw8]

In Fiio Q15 definitely yes. It uses all four amplifier chips in Ultra High for it. In other gaines only two amplifier chips are working.

 

[Magnum Chaos]

Fiio strikes again.

I was able to send my bricked Q15 to the Aliexpress seller, which then he'll ship to Fiio. I hope they are able to fix it, because it was pretty costly to ship back. Anyway, what's wrong in Tennesse? My parcels always seem to get stuck there, no matter if UPS, USPS, Fedex or DHL.

Hi sapporo444, how are you doing with your Q15? Have you solved the problems with FiiO?

Witam. Dziękuję za informacje. Fakt jest taki, że lepiej będzie wykorzystać pełną moc wzmacniacza, i mieć zapas mocy. Używam Power Banku (INIU B63 100W)
do Q15, więc problemu w trybie portable z Ultra Gain też nie będzie.

No offense bro can you use English? Every time you wrote I have to use translator. It's like for me answer is more important than for you.

I sent it to the AliExpress seller, who forwarded it to FiiO on my behalf. I still haven't received it back or gotten any updates. I asked the seller about it, but he hasn’t really responded. I’ll wait a couple more days. I'm guessing that Trump's tariffs are affecting their business.

I have some doubts about the operation of 2 chips (Low, Medium, High) vs 4 chips (Ultra Gain). This is what the attached Fiio Q15 diagram shows. What do you think about it?
