Ghost Audio showed some prototype videos and picture of a new Player, seems quite interesting and some kind of upgrade version of the Z3, it will feature a AK4493 DAC (on the pcb it says AK4490 - don't know if its changed now), Edit: Both Options are available. Hi and Lo output, the OPAs are on a sockets. That's all info so far, some screen shots from the video and picture:

Some new pictures

Great news! It's even more interesting than Caiyn N3 pro =)

We are really looking forward to the new product.

Which confuses me. The SYLVANIA 6021 has a voltage of 33V, but according to the datasheet it should be 100V.

The lamp works poorly.

More Details for the H1:

Big battery with 5600mAh, and available in 2 DAC Versions, price in China AK4490/AK4493 - 90/93 US$ (Why should anyone buy the AK4490?)
Line-Out (I also wonder why anyone schould buy player with a tube and then bypass it?)
Two quite strange features but maybe someone want it...
Available in September.

Google Translation from Chinese:

Play almost all lossless formats, 192k 32b mother soundtrack, 5.1 DTS WAV multi-channel without conversion, DSD music hard decoding,
Configuration one
Independent audio crystal + independent AK4493 DAC solution
Configuration two
Independent audio crystal + independent AK4490 DAC solution

Real Lineout output.
Imported dual triode tube 6021, 30V power supply.
Positive and negative 12V power supply amp, and can replace the op amp design.
Fever non-inductive capacitor inter-stage coupling, non-electrolytic coupling output, power-on delay protection circuit output, the index reaches HIFI, and the thrust is large.
Built-in 5600MAH lithium battery, play WAV format for 7 hours.

It also supports CUE to directly adapt and play! No need for computer division.
It also supports direct analysis and playback of uncompressed DSD ISO DSF DFF! No computer division required.
It also supports USB sound cards! The USB port is definitely more than just charging.
It also supports firmware upgrades! If you have a problem, tell the customer service and it can be solved.
Simple design with five buttons.
The most important point is that it supports folder operations, and selecting songs becomes very simple!
...
Even if you use your high, medium and low impedance headphones, the headphone port outputs 14V slew, 300 ohms and below direct push. 44.1k 16bit -94dB sound-to-noise ratio.

Only three weeks left, gentlemen. Get your money ready! :ksc75smile:
I am going to have to wait until after new years, but I am fairly excited to see what can be done, the 12v power and lamp has me as giddy as a school girl

It's a prototype, don't know what the color will be.
Silver, black, I just wanna hear it, looks awesome, can't wait for the reviews, I expect there to be some flaws, but the modification potential really has me excited
