Does the K3 heat up a lot while in use, the unit gets really hot after a while and even hotter compared to the previous e10k, Is this normal?

pass, It's is their job to do the QC stuff not the consumer, it seems like its the trend with these chinese companies to use the public as their test bed instead of spending money for their actual RnD, what a load of crap from them.

did topping release a fix for all the problems related to the dx3 pro? like hanging and units just dying?

Finally got it to work in usb 2 and 1 mode, no problem now so far and no more clicking and popping noise like when I just installed the K3 in usb 1 without the software. But the Fiio driver provided was the cultprit, wierdly when I run the driver/software installer it doesn't actually install...

Hello I already tried that it doesn't work I also tried just overwriting that file with the one given by an admin from the fiio forum it still doesn't work, its like the software is locked, its stuck on the main page showing "unable to detect usb device" it can't even detect the K3 even in usb...

changing the panel options to Visible doesn't do anything for me, its still blank except for the status which shows no usb device detected, its like the fiio driver cant detect my unit even in usb 1 mode. The clicking and popping is very audible and extremely annoying. I already tried...

sorry double post.

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...

hello is there going to be a fix on the usb 2.0 driver? the current driver 4.47 still doesn't work on windows 7, the system can't detect the k3, also my motherboard only has usb 2.0 ports and is probably related to the windows 10 usb 2.0 port issues as well. Also there's this clicking and...

Send the unit for actual testing on none profit review groups, else the K3 is just another nice looking Fiio junk with false specs that looks pretty on paper and I/O ports that are actually redundant, remember the famous e07k unit which every entry of its defects and engineering screw ups got...

umm no I dont get you at all, dac chips are literally responsible for the sound tuning of the device and AK dacs are far from neutral or flat, same goes for the Ti pcm5102 the e10k is using. amps topology doesn't even matter on this, the only thing that affects is distortion levels. what 2nd...

But you just posted the FR that its flat, now you say its on the warm side while the lsr305 are literally attenuated in the first treble octave. >.>

err that's the e10k, the previous version of this one I wonder how they configured the filters for the AK4452 on this one? and how the 4452 generally sounds.

Those graph doesn't reflect the units actual frequency tuning, its just a test graph showing the bass boost gain. Like the e10k which is heavily V shaped with rolled off extensions.

What's the output impedance of both the 3.5 and 2.5? and also the crosstalk. Is this tuned flat neutral or still V shaped like the e10k?
