Don't know if I'm suggesting this to my brain but connected via USB C/B Input on the SONY ZH1ES it seems next Level Resolution and signature with DENON 9200 & Black Dragon.
Really Brainshaking

So your Sony is doing decoding and then feeding the PCM stream to DX300 or did I understand wrong?
Is that sounding better than straight out of your Sony?

Viceversa... DX300 feeds the SONY

Via LO?
Just wondering cause u wrote usb before.
I wasn't aware that DX300 has usb out feature.
LO would make more sense like others are connecting C9

Dx300 can do coaxial or usb out to act as a transport...

This Headphone is so gorgeous...
Never I met so beautiful thing like this.. all finishing to the small detail is oustanding....

You focusing on looks or sound ? Soundwise it is average.

true, valid point.... below are my impressions if you want to know

My impression at that time


take this as grain of salt, since the unit is just arrived, and not yet finish its cycle of burn in...

MG, open back, Agile sounding, Focal sound house, BASS tight decay yet puncy. Vocal a bit forward, smoother treble (compare to original Clear). Better in height soundstage. Impressive Depth (good imaging)

R10, Close back, more relaxed, laid back (like Sony IMO), more articulate Bass and Mid, with smoother treble. Wider Soundstage. a bit flatter Depth still above AVG imaging IMO...

Well, I will get back again to demo.
for now, My interest is on R10...

and yet, my head still stuck with Verite Open, so my bench of expectations is a bit to high...

that's how I exp at that time...

edit : R10 image... just to give better understanding... the R10 build quality is so sad compare to MG... in many aspect (except the wood cover)... with price that I can consider similar

What questions? I don't have any questions.


FPGA is a programmable gate array chip that you program via VHDL or Verilog , then it does what you want it to do. If you want it to add 2 and 2, it does that. If you program it do DSP, it does that. If you place it between a camera and controller and program it to manipulate video data, it does that. If you program it to support jitter correction, it does that. If you program it to act as a device to be controlled as, for example, a USB device connected to an internal USB bus, it does that. If you program it to act like a SPI master or slave it does that.

When I check the ALSA information:

DX300:/ $ cat /proc/asound/cards
0 [sdm660sndcardi2]: sdm660-snd-card - sdm660-snd-card-i2s
sdm660-snd-card-i2s

Before starting playing on Mango application:

DX300:/ $ cat /proc/asound/card0/pcm0p/sub0/status
closed

After I start playback on Mango:

DX300:/ $ cat /proc/asound/card0/pcm0p/sub0/status
state: RUNNING
owner_pid : 3212
trigger_time: 29618.818513646
tstamp : 29627.003569112
delay : 3840
avail : 0
avail_max : 1920
-----
hw_ptr : 362880
appl_ptr : 366720

Checking the HW parameters while playing 44 kHz audio:

DX300:/ $ cat /proc/asound/card0/pcm0p/sub0/hw_params
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 1920
buffer_size: 3840

Checking the HW parameters while playing 352 kHz audio:

DX300:/ $ cat /proc/asound/card0/pcm0p/sub0/hw_params
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 4
rate: 352800 (352800/1)
period_size: 15360
buffer_size: 30720

...meaning there is no bypassing of ALSA, and the sample rate setting has been done by the audio subsystem. This can be confirmed also by checking a 3rd party application, such as Qobuz:

Checking the HW parameters while playing 96 kHz audio using Qobuz application:

DX300:/ $ cat /proc/asound/card0/pcm0p/sub0/hw_params
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 96000 (96000/1)
period_size: 3840
buffer_size: 7680

What do we have here?

- The resampling has been by-passed at the software level, but without bypassing the kernel, _before_ the data reaches the FPGA.
- This is most probably done by manipulating the Android audio subsystem, because it also works for 3rd party applications.

Thank you so much for the verification .... I don’t know why so many conspiracy for Dx300 By some people ?

I wasn't aware of that feature.
Thank you guys!
Edit: great potential for experiments and connecting different DAPs.
Am looking forward connecting DX300 to DX Max once it's back from repair
I mean you could potentially make use of DX300 DAC tuning and MQA decoding capacities and afterwards superior amp sections from successive devices avoiding any analogue connection loss.
If that works it can mean an even better desktop setup when combined.
Very curious about the outcome of that experiment.
Wondering a bit why no one else besides WiseRooster has been reporting about that or maybe I missed it during the last few hundred pages

Not sure if this has been discussed before, but is there any idle off timer functionality on the DX300? Because I can't find it on mine.

Which one do you mean
- display idle timer (That's an Android setting in the display section that should be easily found)
- music play timer

The Voltage swing on the Dx300 Amp11 is about 6V, and the Max is about 8V. So the Max has a better driving power and so on is really a thing. Better dynamic, different textures, more enveloping soundstage, but they are so close though when using Z1R. It is literally a 9.5/10 in width and 8.5/10 in depth from Dx300 VS Max

Yes, different signature and textures as mentioned. However, the dx300 is more fun with Digital filters to have some real differences rather than the Max

My conclusion is that Dx300 can serve as a Miniaturized Max just fine and while offering alternative signatures

*Noted* talking about the latest Dx300 Amp11 MKII

Practicality side: Dx300 can keep on going and going and going...heck, listening all night and is sitting at 56/67 batteries for PCM files 44.1. Then it also does not get warmed up and so on. The UI is blazing fast like “the flash” VS “King Shark”. The screen is awesome! Though if it was AMOLED .... well!

Vince, have u tried connecting DX300 to Max on USB?
Does it work and will it bring like a married sound signature combing both strengths?

something like what the R8 and Android based Walkman has where the player will shut itsef off after being idle for a set amount of time.

Wow! I have not, and stacking them both this way is not something I want to look into lol!

Technically the Max will only be digital transport into 300 to take the pros of FPGA but losing in Sabres and powerful amp, and the other way around you will lose out FPGA merits
