I don't know much about this site but they seem to be doing a very detailed , trough review of DACs/AMPs .
His review isn't much favorible to K3 . Any similar experience?

https://www.audiosciencereview.com/...iew-and-measurements-of-fiio-k3-dac-amp.6859/

I was going to buy this to use with Hifi 400i , but kinda back pedalled .

FiiO's own documentation talks about intended use 16-150 ohm - ie primarily portables and IEMs. So he tests it with a 300 ohm HD650 and suggests it performs poorly. Well duh!

And talks about the noise floor - but doesn't mention if its audible.

He's a Topping fanboy. If you use the K3 within its design operating parameters, its a perfectly good little DAC/amp. if you try to throw a high impedance, or low sensitivity load at it - of course its going to struggle. Its not what its designed for. Its like attaching a towbar to a mini, then complaining it doesn't have enough grunt to tow a trailer. Really dumb stuff.

\Basically, K3 is great if you use it with easier to drive cans.

400i requires more power than K3 has to offer, having both I can say that you probably want something with more power.

Shozy CP and FiiO K3 - they look pretty fun together!

Hifi 400i is 35Ohm . Shouldn't be K3 enough is it supports upto 150ohm?

Some planars might be low impedance, but they are generally low sensitivity - meaning they require more current. The K3 is ideal for small desktop with IEMs and low power portables. It’s going to struggle with anything high impedance or low sensitivity though.

400i requires more current than K3 has, I tested both, it gets fuzzy, 400i eats way more power, something like XD10 Poke is the least I'd recommend, but the least expensive good solution I found for powering 400i / 4XX / Sundara at this moment is QLS QA361, and QA361 also helped me understand that Sundara / 400i requires both current and high voltage, since with that little DAP you can set whether it has high voltage, high current, or both

If anyone has K3 for sale in EU, PM me please
I already owned it, but sold it and now want it again, lol.

Anyone tried to feed another DAC using K3's Optical out . How its performing?

Optical is pure data, it should be exactly the same as a normal USB (?)

Pure data, it performs flawlessly

Finally a dac that uses usbc! Wondering if it supports cell phones?

 

[Antenne]

I'ts not recommended, too power hungry. Although there are some reports that it worked.

Dear friend,

Thank you for the kind interest on our products.

No, it is designed for computer mainly.
If your mobile phone supports otg function, you may consider our Q1MKII instead.

Best regards

Works, but even with Mi Max smartphones that are 90% battery, it draws too much for me to recommend it

Yep, works for me with Xiaomi Mi Max 2, Mi Max 3, but draws a touch too much power

has anyone encountered a problem where windows 7 can't detect the k3 on usb 2 mode? also in usb 1 mode windows detects the k3 as a speaker not as a usb device like the e10k or previous versions, and equalizer apo doesn't work with it.

also there is this annoying popping and clicking at the start and end of every audio being played.

For that issue see my post #168
