Greetings,

I just purchased the Bower's & Wilkins PX8 last week,and bought a Fii0 KA11 DAC USB-C connected to my iPhone 15 pro with 3.5mm jack and when playing a music at 24bit/192kHz wired with my DAC my output to my headphones only goes up to 24bit/48kHz sometimes it goes to 192kHz it all depends. Could it be my DAC converter is faulty ?

Cheers
 
What source are you listening to? If you are streaming, then recordings have different bit depths/sampling rates and you’ll see different displays accordingly. Most importantly does it sound good, and is it better than listening from just your iPhone?
 
Greetings,

Yes it sounds good,but when I have my DAC plugged into my iPhone with 3.5mm plugged in,and it's playing a music track playing at 24bit/192kHz and going to my wired PX8 headphones but its on;y playing 24bit/96kHz to my wired output headphones. I was just wondering why ? If my external DAC is faulty sometimes it goes to 24bit/192kHz to output headphones
 
Have a look at the user guide - specifically what it says about 'UAC1.0 & UAC2.0 modes' and how you switch between them, using the Fiio control app.

I think that might help you.
But don't be disappointed when the higher rate doesn't sound better.
That won't be the fault of the DAC - more the fault of the hype telling you that it will.

your Px8 already has an onboard DAC/Amp? why did you get another DAC/Amp?

also higher sample rate has never meant better sound.
 
Oh I did not know this,so it can play 24bit/192kHz with the onboard DAC/Amp ..I can still return it to Amazon only paid $60 for it... some guy on YouTube recommended it.
