DX340 iBasso developed Discret DAC, Easily replaceable batteries, Amp Modules! ***New firmware on 1st page. v1.04 local update. ***

[Aetherhole]

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.....

DX340 has a surprising amount of power. It could be a flat out replacement for desktop systems, but but that’s ultimately up to preferences and other various factors. Just for reference you can see my desktop setup in my signature.

That said, I’ve tried my own Immanis on it and been very surprised and happy with the results, enough I wouldn’t mind taking it as my portable solution. I’ve also tried Caldera Closed, Susvara OG, and Susvara Unveiled on the DAP, too. Most of those mentioned that I’ve tried are harder to drive than the Arya or HE1000. I’ve tried them on both battery as well as the 12V option. 12V is better, but the standard unplugged version actually works quite well.

Micron industrial card (mouser.com)....

I bought one of these when I got my DX320, due to the recommendations that it makes a difference to sound quality. It failed as I was filling it up with music. Was a trial getting a full refund from the seller. Never ever again.

And I'd probably not have noticed any difference in supposed sound quality anyway....

Meanwhile, ive been using SanDisk for many years in multiple devices and only ever had one fail, and it would have been one of my oldest ones.

Needless to say, after the Micron fiasco, I grabbed a 2tb SanDisk for the DX320, when it performed faultlessly, and it now has a new home in my Dx340.

What is that case in pic 7 of 23? Looks like a perfect fit.

It is the perfect size. Use it all the time.

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

Select the 1st app in list and choose Battery and then select Restricted





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.

Sorry to say, but I do not endorse aforementioned debloating procedure. There's no need to uninstall that many packages and it's likely to cause more problems than it solves. My take on this topic can be found in an earlier post here, including some tweaks (up-to-date).

For those who know how to use ADB from Android Platform Tools: below you will find some useful one-liners for debugging purposes. Just copy & past into ADB shell (use Ctrl+C to exit, applies to all 3).

# adb shell

# Check what apps are causing CPU spikes (watch column "[%CPU]": 1 core=100%, all 8 cores=800%)
top -d1

# Verify what packages are actually loaded/running
for l in $(cmd package list packages); do { p=$(pidof ${l:8}); (( p > 0 )) && echo "$l $p";}; done

# Check at what frequency the CPU cores are running (1st 4 cores are efficiency cores, 5-8 are performance cores). This requires you to run ADB as root.
adb root
adb shell
watch -n2 cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq

Btw Yes, ADB can be run as root, since the firmware is built as a so-called "userdebug" target. That also means that rooting - for most use cases - is not necessary. Something for a future post...

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.

I listen with the HE1000se at home. No problem driving these battery only, Dac gain Low, Amp gain High.

I use the exact same settings with my HEKse, volume between 45-55...sounds really good!

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.

Everything is preferential. R2r/ds/1bit. I don’t like the sound of dsd, with that softness and fluffy airbrushing of the edges. R2r is organic but muddy usually with high noise floors. Ds is usually more digital sounding and etched.

Just have to pick your poison and see the synergy between source and earphone. I don’t believe in brain burn in, and all these psycho acoustical things.

It’s like people telling you the latest anaerobic, honey processed, thermal shock, macerated coffee beans are amazing…..but all I like is a high quality simply washed coffee. I don’t have to burn in my brain to like it if I don’t because of peer pressure. There is no wrong answer.

Yepe, just like we dont all love chocolate or coffee , while the majority do. I usually advice when a new device isnt your cup of coffee, just sell it and move on as soon as possible, because it value hold

I have a question, are you listening using the tidal app or are you using a browser (e.g. chrome) with tidal in usb dac mode?

Brain burn in is basically just getting used to the tuning, which is a very reasonable element of a good DAP experience instead of trying to find a DAP that sounds exactly like your old DAP.

It's more sane than thinking your headphones or cables burn in overtime.

 

[Whitigir]

Headphones, cables, especially electrical components do have burn-in period. Even Sony states it on the technicality of the walkmans.

Do not state that electrical components burn in is a belief when it is scientifically proven. When someone do not understand some facts, doesnt mean it isnt a fact and a belief alone by itself

Every capacitors have it Datasheets tested and published, not for the period of hundreds of hours, but thousands as in to show the reliability. But there are a short period that the capacitors will have it chemical reactions from the dielectric, under operations, will form and get primed to be at a steady equilibrium values and parameters over thousands of hours which could be decades. These stuff do get weaken, but it takes a long time, which is normally longer than the period that we own it.

For example, this is a snapshot of KEMET capacitors and it parameters under tests and endurances

Tolerances is a thing that all electrical components have to meet and catagorized before productions.

Again, audiophiles people chases for the last 5%. If they cant even hear the changes from 20% tolerances down to 5% differences, would be underestimating people that spent Thousands of dollars in this hobby. For anyone who discarded and disregard these electrical matters, you are just showing your limitations in what you think you know. No offenses

Yes! The burn in of AMPs and DACs are very real and it makes sense since these components have tons of sensitive capacitors that can directly influence the audible frequencies.
AMPs also react to temperature, a warmed up AMP will sound more fluid than a cold AMP.

I asked because Tidal from the browser in USB DAC mode sounds like YT music, or even worse. Install USB Audio Player PRO (UAPP) and use exclusive mode. If you are very used to DX320, the process of unaccustoming may take some time. As for the burn-in, the changes are rather subtle. In my case, I felt the most softening of the high band and maybe some improvement in transparency. Either way, I don't remember anything as good in terms of scene and detail as DX340. I also had DX320 like you, so I think you should give DX340 a chance and get to know it a little better. It is very possible that you will change your mind.

@ToneDeafMonk

Sorry can you also post a link for the same 3.5x1.35mm 12V adaptor piece you are using with the LHY LPSU cable?

I ended up opting for just buying an adaptor piece but the adaptor I bought from Amazon is a bit strange as it is 3.5x1.35mm male end but is a bit longer than the stock 12V plug that iBasso supplied.

I tested that it works but wouldn't a more secure connection be better for sound?
