A couple of tips so far...

The DAP comes with a front screen protector applied already, don't do what I did and stick a glass one on top too! Haha. If you put the glass one on the back it won't sit in the leather case fully flush as it'll make it too thick. It sticks out just a tiny bit and it makes the top slide down menu difficult to reach. So if you're going to put a protector on the back plastic use the more flimsy ones. Those fit fine

Also... the rubber cover for the DC-IN port opens like this.. I spent 30 minutes trying to open it the way other way, lol. Once you get it open it's relatively easy to remove it after that. When you plug in the 12v charger you will still see the battery % draining and that is normal. This is bypassing the amp battery and unlocking the extra gain and the battery to power the DAP itself will still discharge.

You can use usb charger to charge up the digital battery

This confirmed to me that the 340 is using battery for digital processing in desktopmode. It is a good implementation, because the 1 bit DAC works closely to unity gain, it were in house developed to optimal performances with battery voltage as a source. There is no need to jump through the LDO loops, which we all know that the more loops = the more errors.

What i am saying is that Digital processing is better off from battery power sources, and it is even better when it was inhouse developed to optimization. The amp, however, can always utilize more power!! Hence the desktop mode !!

Yep that is how I have it set up at my desk with both USB C in and 12v in.

Ah so very much like the Dx320 MaxTI?

Not quite, this charges entirely through USB C, so one cord only. The 12v in doesn't charge anything but lets you bypass the internal battery for the amp which allows you to get the higher gain mode, which to my ears is worth using if you are stationary. There's a noticeable increase in authority and power behind the sound.

Beautiful thank you for the explanation. That’s pretty cool.

Imagine an audiophile dedicated linear PSU

Also, a rechargable 18650 bank with 12V output

Imagine the sound when rooted and optimized If like the DX180 (same CPU in both) CPU cores will need adjusting and there are at least 60 modules that are not needed. Been using Magisk module script to optimize other settings for a few weeks without any issues. I would also use a Swissbit MicroSD.

I'm confused, how is this different than the ibasso dx320 and the ibasso dx 320 max ti, besides the price? I'm looking to upgrade from a FIIO M23.

Different DAC chips, better construction than the DX320 still with ability to change amp cards - imagine AMP14 like card with AC12V for more power Much better QC than Fiio and much better customer service from Paul.

Here are some of the key differences in addition to what Matt mentioned.

iBasso DX320
• DAC Configuration: Equipped with dual ROHM BD34301EKV DAC chips, the DX320 offers high-resolution audio decoding, supporting PCM up to 32-bit/768kHz and native DSD up to 512x.
• Amplification: Features a replaceable AMP card design, with the stock AMP11 MK2S module providing 4.4mm balanced, 2.5mm balanced, and 3.5mm unbalanced headphone outputs.
• Operating System: Runs on Android 11, offering a modern user interface and app compatibility.
• Display: Boasts a 6.5-inch bezel-less design with a 2340x1080 resolution, providing a vibrant and responsive touch interface.

iBasso DX320 MAX Ti
• DAC Configuration: Utilizes a quad ROHM BD34301EKV DAC array, enhancing dynamic range and spatial resolution. It supports PCM up to 32-bit/768kHz, native DSD512, and MQA 16x unfolding.
• Amplification: Features a discrete ‘Super’ Class A amplifier design with an analog volume control via a 4-wiper stepped attenuator, ensuring precise volume adjustments. It offers up to 9Vrms balanced output into 300Ω loads.
• Design and Build: Constructed with a titanium chassis, it is lighter than its predecessors. The device includes a 5-inch 1080p IPS display and a removable back panel for easy battery replacement.
• Operating System: Runs on Android 11 with iBasso’s Mango OS for dedicated music playback.

iBasso DX340
• DAC Configuration: Introduces an in-house developed discrete DAC, comprising 16 sets of cascaded 8-element PWM DACs. This design supports PCM up to 32-bit/768kHz and native DSD512, aiming to deliver a unique sonic signature.
• Amplification: Compatible with AMP12, AMP13, and AMP14 modules, and comes with the new AMP15, allowing users to tailor the amplification to their preferences.

• Operating System: While specific details are pending, it is expected to run a contemporary Android version with iBasso’s customizations.

Summary
• DX320: Offers a balanced performance with dual ROHM DACs, a large display, and modular amplification, suitable for users seeking a high-quality DAP with modern features.
• DX320 MAX Ti: Elevates the audio experience with a quad DAC setup, Class A amplification, and premium build quality, targeting audiophiles desiring top-tier performance.
• DX340: Presents an innovative approach with a discrete DAC design and flexible amplification options, appealing to enthusiasts interested in customizable and cutting-edge audio technology.

Wow, thank you so much for taking the time and summarizing everything for me. I'm definitely going to pull the trigger on the dx340 once bloom audio has it.

What are amp cards? Do they produce different sounds and what are the benefits? Also, are they easy to install?
I apologize for asking so many questions, I'm still learning

 

[Kangeo]

Haha I have to agree. For some reason the iBasso DC Elite sounds so much crisper, smoother, and wider than the FIIO M23 which is double the price of the DC Elite
So if the dx340 produces anything similar to the iBasso DC Elite, im sold

Remove 2 screws and pull out to change cards. I would wait until newer amp cards are available for the 340. I have a feeling there will be very nice upgrades to the 320/300 series cards. Different cards will have a different sound like AMP14 - tube amp vs AMP12 allowing you to choose which you want with each IEM or mood. DX340 is Android 13 like DX180. They did a really nice job in DX180.

i just wonder how the DX340 DAC sounds compared to D16, assuming they are same 1bit solution with different amps. just debating which one. my use case is portable for the road but also feed a desktop amp for headphones
