V2 is what it should've been from the start. Now it is usable at last, hopefully this is only the beginning of better FiiO software.

Using 4.4 mm (and desktop mode on KA17), the KA17 has better soundstage and layering. Micro-detailing is slightly better on the TP50 but the TP50 is more harsh/sterile.

However, beyond stock tuning, the KA17 has PEQ on android app, which can actually boost the clarity and upper frequencies to hit almost the same amount of micro-detailing as the TP50.

TP50 has weaker power even on 4.4 mm.

thank yo very very so much my bro basking. wow.. very detailed information for me us.... best answer. case close

Is it only me, or in EQ OFF the DAC sound very different than in User 1, User 2 and User 3? I found it quite puzzling because I didn't apport any modification to said profiles trough PEQ. Is it supposed to work this way?

Just tried V2.00 - this is a major update

I think I might update my review as this version adds lots of good features. Especially for those with a Mac or even an iPhone (as the editing of the filters in Chrome on a Mac works). This new website for editing though seems a little buggy in that it connects and disconnects randomly within my Chrome but I was able to change the EQ filters and it seemed to save them back to the KA17.

Also, some of those other missing features are also in this upgrade like Low pass / high pass filters and I see there is an updated FiiO Control application.

Though the names of the custom filters aren't exactly the same when I look at the EQ profiles in the FiiO Control App - I guess there are a few little bugs still but this update is so much better for providing control over the KA17.

Does it have shelf filters?

Is this "low shelf" and "high shelf" filters or something different?

Sorry they are low shelf and high shelf filter here is a screen shot:

Here it is via the new website (only works in Chrome and Edge for me - not Safari or Firefox):

One very nice side effect of the fiiocontrol website is I am pretty sure either a separate UI could also be built to 'upload' exported PEQ Filters, a feature I do hope FiiO add anyway but the community could do it first or even a Chrome Extension to 'enhance' the FiioConrol website..

I can see the code (in Chrome's developer console) writing to the FA17:

Dear friend,

Yes, the engineer has the plan for adding import/export PEQ function for the KA17.

Best regards
