6-days in. Only bliss. The DX340 surely cannot be everyone’s cup of tea sound wise, but it’s mine with the right transducers. For the ones who have/had the R8II, I consider the DX340 as an improvement in all registers.
Not in terms of dynamics and “weight”. The dx340 to my ears is more ethereal.

If you listen to metal, for example, the r8ii might be a better choice.

I'll update again in a day1or two now that it's been reset multiple times
Well a couple of days have passed since resetting my 340 four times. Immediately following those resets I was able to listen for about an hour and had no recurrence of the left channel clicking or white noise. I didn't get a chance to to use it much yesterday so it just sat in standby mode overnight. I got up this morning and the battery drained 33% since last charge, sitting in standby. I started playing music and about 5 minutes in the clicking was back and started increasing in volume and frequency as time went on. Did a restart and it disappeared for a couple of minutes, then came back so I started playing with gain and harmonic settings; just rotating through them. Adjusting the DAC gain didn't do anything but with each click Harmonic and with each click of amp gain brought static to the left channel. Since I'm the only one reporting this "white noise" and clicking problem I'm assuming it's hardware and likely the amp card. I'll get hold of Paul and see what he has to say. Whatever it is, I'm confident they'll take care of it - it does seem to be isolated to my device.

On another note - the idle battery drain is also concerning. I've turned off location, screen rotation and has not background apps running. As the screenshot shows. 25% of the 33% drain is system UI and Android. Any ideas how I can mitigate this?

I had to buy tool kit $45 from ACE to get the stupid torx screw to remove AMP card but battery really EASY to replace. End connector of battery held down with metal clip that is screwed down. Have to put back together now but less than 5 mins to take out. Did not need any pry tools. Battery is back in place. Very easy to do.
What is that case in pic 7 of 23? Looks like a perfect fit.

Since this related to optimization I will make an exception and post here. CPU is NOT set correctly. It will NEVER be allowed to enter lowest frequency so even at idle it is using way more battery than required to stay in idle state which is part of the issue. Only solution is to Root and set CPU properly. I am sure one or 2 of you is going to say this will cause issues but I have been running my Ibasso DAPs this way for over 2 months and no issues at all. See my guide on DX180 optimization and you can restrict background battery usage for each app right on DAP. I would do a complete FW flash using Qfil followed by Recovery mode Data Wipes and see if that fixes it. I will post guide for that once Paul gets back with the missing settings I do not have so it works properly. When I was messing with my 340 with Qfil I had times where I had NO sound, NONE at all. Luckily I was able to fix that by luck. Willing to bet money its software issue, not necessarily a bug but FW upgrade did not apply right and this is why QFIL is best way to do updates. Never had any issues with DX180,DX260 or DX320 when I used Qfil. DX340 I do not have all the settings so doesn't apply right currently.

Attached is list of modules you can copy all at once to disable bloats. In ADBAppControl goto Console and on right choose shell. It will give you command prompt. Select the 1st group and Hit-Control-C and then goto command prompt/Shell and

This pastes all the commands and hit enter. Then depending on your use requirements you can copy the bottom section ones that apply to you.

Battery Usage Settings for Remaining Apps - Restrict background battery usage

After you are done disabling APKs you wish it is best to set the services that are not directly related to audio to “Restricted” which tries to minimize their battery impact when in background/not being used. This should be the final step you complete.

  • Goto settings -> Apps -> See All apps
  • Goto upper right coner where there are 3 dots and choose show System

When you want longest battery life use LOW GAIN, guessing low DAC gain as well. We do not know how much AMP15 uses of battery since Ibasso took that indicator out. Also put DAP into Airplane mode.

Having said everything I've said above, as much as I enjoy the 340, I am considering selling it.

I travel a lot and I need a device that's got enough juice to last a flight. At 520 grams, having to strap a powerbank on to get me through a flight is just highly impractical for me. Not to mention the combined weight with laptop, charger and tablet would probably put me over my carry-on limit. If there's anyone watching this thread and considering a DX340 - hit me with a PM - mine only got a couple of charge cycles on it and we may be able to make a very favorable deal for you. I'm still not 100% convinced I'm going to sell, I'm not 100% convinced I wont' so let's talk.

Matt, isn't it possible that these bugs that some people here are reporting to be fixed by future firmware updates?
I mean, probably not all of them (maybe some of them are hardware issues also).

But I did not tried to root, I even didn't reset after updating the FW. And I didn't encounter any issues with abnormal battery drainage in idle, or charging issues.

Maybe someone with such knowledge could say if one bug is FW fixable or that device needs to go back to Ibasso / dealer for a replacement, so anyone who has a problem with the player will know how to deal with it.

You're star, Matt. I'll complete this de-bloating and see what it does for the battery. Been listening for the last hour and no clicks, pops or walls of noise. I can't figure out what triggers it, but at least for the last hour there was none!

ITs hard to say. Until I can use QFIL to flash FW fresh I won't know. I do not trust OTA FW updates. Have read too many posts of reports of strange issues. 99% of the time its software. Ibasso has really stepped up their game with QCC especially on the DX340. Hardware is solid. Unless there is obvious hardware issue the 1st thing a dealer is going to do is Factory reset and then FW flash. Like me they do not have the settings for FW flash yet. Any real bugs will be fixed in future with updates. Ibasso is good about that. This is a brand new release so bugs are expected. 6 months from now you won't hear of any. I have emailed Paul and volunteered to be a beta tester for any new FW before its released for free since I own 2 DX340s to catch any issues before its released to everyone.

Hi guys,
A couple of questions:

1.
How's is the DX340 with headphones like the Hifiman Arya/HE1000 etc ? Can it drive well enough connected to the 12V option ?

I'm looking to maybe replace my entire DAP/amp/dacs for a DX340 and use it as my main desktop DAC/AMP with the external 12V AC option...
Just a bit worried it won't drive the Arya as well as my old YULONG Aurora (Class-A 4W) does.....

2.
Did anyone here tested the USB DAC option on Linux ? I ask this because I have many issues using my Hiby R6 Pro II on piCorePlayer on my raspberrypi living room speaker setup, ASLA was a nightmare and it never recognized the maxium output rates of AK4499EX on there (DSD1024 for example, wasn't an option on Linux) (and btw, Hiby's response for this was a straight up "just don't use HQPlayer, it doesn't provide any audio benefits" lol).
I will definitely use this DAP with HQPlayer, so I want to be sure all available output rates are available in both Windows and Linux.

just got my dx340. 20 hours into the burn-in i tried them with the below songs paired with the a12t’s.
https://tidal.com/track/22757088?u
https://tidal.com/track/71038445?u
https://tidal.com/track/294508491?u
both sound not good compared to my dx320 & dc elite.
musicality is good however more intimate, less clarity on the vocals and the soundstage leaves much to be desired over the dx320 (for me) which has seen lots of use.
i tried harmonics regular/normal and odd+, gain on high.
not having much fun and thinking of going back to the dx320. shame i can’t return it as i paid a bunch in duties,
love the look and feel which reminds me of the sp3k.

will burn-in make enough of a difference?
i’m doing it at just below 1/2 volume with low gain and dac on low.

From my experience you have sort of give the DX340 more time to try to understand the tuning better. The strengths will slowly come out, it is a unicorn DAP and I thought I loved the DX320 but this thing just provides so much more.
12v DC-IN Super Gain mode is just addicting and mesmerizing.
When I realized what this DAP is capable of for now and in the near future, this is more special than any DAP I've owned.

We were all used to the tuning on our usual DAPs such as the DX320 ect. When we hear a different tonality we are quick to point out the weaknesses on it based on our familiarity of our other DAPs. This is a very common thing, look at other DAP threads and you will see the usual pattern.

As for burn in, you probably need a little more runtime with your AMP15.
Brain burn-in is very important as you will start to notice the strengths of the DX340 with AMP15 if you give it more time.


Also, try not to update the firmware right away, the latest firmware is buggy and can come with different issues (which are already reported in this thread).
Wait for the Lunar New Year break to end in China so we can get the fixes in the next firmware update.

Let it burn in. If still not to your liking flash latest FW using Qfil. As soon as I get settings and test I will post a guide on how to do this. It's possible it's not the DAP for your preferences but also possible there is a software issue. My 2nd 340 arrived after just being reset by seller and would not boot. Best to try that and see before selling. I flashed my 1st unit I had no sound and then sounded horrible like not even same DAP. I am lucky I was able to get it back to proper SQ.
