I use sometimes the DJ44A 2.5mm to 4.4mm from DD, but I am still not sure it is worth to use it on a Kann Alpha.

recieve my KA today and It's heavier than my Portable HDD LOL, after applying the Screen Protector the Screen got really blurry What?
Yeah the matte screen protectors do something funny to the resolution of the screen. I'd suggest buying some glossy ones, that's what I did for my SE200.

@Onik: like you, i was initially surprised as well of my Kann Alpha's weight upon receiving it.

however, i immediately, upon its first use, was amazed at this diminutive device, its capabilities, power output, dual dac chips with on-chip, baked-in hardware MQA full unfolding, etc.

considering what it does, i continue to be amazed despite its substantial weight. it's a marvel of modern technology to me.

I didn't use 1.0 .. but definitely the 1.01 is really annoying with any wifi based listening AK Connect (NAS) or Qobuz (Wifi stream) => Wifi falls asleep and music stops every 15 minutes !!!
It doesn't happen with music on SD or OTG SD reader.
With Wifi it happens even if you change the parameter for AK Connect sleeping feature.
It's an amazing issue not fixed yet !!! and make this DAP almost unusable with streaming features.

Is it safe to update 1.01 latest? Also why my New KA charging really slowly with usb c cable?? Edit: found out that I need 9V 1.67A adapter to charge faster.

iirc, in terms of lithium cell maintenance, slower recharging is better for the batteries in terms of longevity.

you might wish to research into that a bit to ensure better longevity if that matters to you.

i recharge around once every 3-5 days, so assuming once per 4 days, 365/4 = 91 times per year.

most lithiums are said to be able to cycle around 400 to 500 times before their capacities shrink to really low levels, so i'd say that i'm good for roughly 4-5 years before i would have to be concerned about my batteries needing replacement.

by then, i would suspect that new technologies would have been introduced and i'd be itching to get the new stuff anyway.

exactly that is the problem that I have, I think that the software is not well polished, if they do not solve it then we will sell it and buy a fiio m15 that apparently works well

My Fiio M11 has some issues too .. at least it has a limited BT 5.0 bandwidth and for a very long time BT volume was way too low (till one of the last firmware), the volume knob is quite erratic and uncomfortable to use, battery life is rather limited (anorexic ?) in balance mode and at last available power is really behind the Kann Alpha (which is the main issue for me 5V compared to 12V of the Kann Alpha).

I am more and more afraid that we have to consider that most of the Chi-fi hardware/software are never really fully operational when they are sold and support is almost non-existent... Fiio is sometimes producing some new firmware to fix more or less some of the issues, but A&K ? 1.01 seems to be there for 2 months and almost unusable for streaming more than 15 minutes...

Well damn AK did it again just like they did with KANN original(semi bricked) which made me sell it for £350 luckily the buyer didn't bother.

After hating them for almost a year I still bought their new KA and the reason is I did really enjoy KANNs SG, and the price for KA wasn't a big deal for me.

Right now I think This company is not really trusted for their dodgy firmware and services. I would say keep away from AK if you care about your money.

Something like this. They are cheap and available everywhere. Made my charge time go from 6-9 hrs via USB 3.0 computer to 2-2.5 Hrs. It charges so fast I have to watch it closely as best battery health is understood to be between 20%-90% for longevity. Charge to 90%, use to 20%, every 3 weeks or so I use the slow charge computer USB to top off to 100%. Try not to let it dip below 20%
Fwiw, I have an SE200 and it runs great without any issues. That's a bummer on the KANN line though. Hope they address the problems.
