I will probably attend.   I have a new preamp and phones-amp to demo (a sercona PGA preamp that I co-designed with jeff wilhelm):       I could use a full table or half-table if you are tight for space.   also looking for beta testers.  I'll have some blank pcb's with me for both the...

it does not have to be all-or-nothing.  you could make a linkable library available (or just some .o files) and some headers and draw a line where the source ends and binary blob begins.  it happens enough that its an understood problem.   talking to the SoC chips is asking a lot; so give an...

there are two tell-tales about incorrect rotary encoder handling:   1) turning too fast causes skipped events, possibly even moving you backwards   2) turning too slow causes false events and 'bounce'     sadly, both of those problems exist on the x3-2 wheel.  pretty odd that even turning...

well, like I said, its a long-shot and lots depends on how their system is designed to work and how they read the encoder.   but it does seem very much like when I tried reading rotaries and only used two states instead of 4.  that, and lack of frequent enough polling of the 2 lines on the...

wow, it was $48 when I checked it, last.  grabbed 2 at that price.   the first one I bought, right when the x3-2 came out, costed $80, so its back to the 'old' price now, I guess.

I never heard from anyone at fiio about the scroll wheel issue.   the issue is that rotary encoders have 4 states as you turn the knob and a lot of the wheel devices out there only seem to track the 2 obvious main states, but by taking that short-cut you miss the middle states and those help...

cool. and just to be clear, we are talking about using the 200gb card in the internal sd slot and not via usb otg via an adapter, right?   when I hear 'browse mode' I think usb otg, but maybe I'm out of date.   yes, right now, amazon has the 200gb card for $150.  very very tempting! ;)  was...

sorry if this has been answered: but curious if the new (?) 200gb micro-sd cards are supported?  or if they even -can- be, in this player?

if its ok to post a link to an external show-report:   http://www.hometheaterhifi.com/home/show-reports/show-report-head-fi-meet-july-18-2015.html   ob disc: I was mentioned in that show report, but I am not connected with the site.  I met john for the first time at the event and spent some...

it was fun talking to everyone who stopped by.  here's what I brought this year:       Left to right: an arduino thermostat (yellow oled display), spdif switch with input selector and sample-rate display in large LEDs; the Fiio x3-2 audio player, an AK4399 DAC, a zibgee-ir gateway (remote...

my wish-list for the x3-2:   I'd like to have CTIA remote control function (on the left hand side trrs jack) even when the right-hand side is inserted and running either line-out or coax/spdif out.   I'd like to see the scroll wheel be more responsive and not show the 'bounce' problem it now...

disclaimer: I am a software and firmware developer (but not for fiio) ;)   fiio: I am willing to bet I know why your scroll wheel is slow and sloppy.  if you want to see the better algorithm for how to scan the rotary encoder, PM me.  I have a table-driven bit of code that works very well and...

android inline remotes do NOT work, that much I know.   the protocol seems to be about the # of 'taps' you do on the control buttons, on the inline remote.  I found this by trial and error.  its not resistor based like you might think.   I ended up building a box that lets me control the x3...

I'll have the fiio x3-2 with me.  I'll probably be demoing my system with that as the primary source.  I'll have an AK4399 dac with me and so you can compare the sound of that external dac to the onboard cs4398.  to me, the onboard xtal^Hcirrus dac is fabulous.  no complaints here.   the...
