  There is not any increase in temperature in my x6, even with 12v 2.5A it always cool normal.
Yes x6 much better E10K smile.
 
 

Hi again,
 
I wanna ask you about one issue that I noticed recently.
 
When I give a little jiggle to the jack of x6, I can hear a distortion. Also the port is little loose-slack. 
 
It reminds me the time when my motherboards jack is little defective...At that time when I jiggled/shaked the headphone jack on motherboards or turn it to left-right it was giving a some sort of distortion. Sometimes I was loosing a channel. 
 
On fx x6 the channel seems solid and proper but same as my mobo when I turn or jiggle the jack it gives distortion. (I was never had this on Fiio) So I'm wondering if I had a defective unit. 
 
Can you try it on yours please ? That way I can truly understand if my unit is defective or not. And I wonder if its a serious issue or not. Will it cause a problem in the future? Because when I'm not shaking the jack on x6, everything seems okay. Should I send it to RMA ?

Only show defect p10 jack, I already discard it and today use a new p10 jack without distortion, this was the only defect that my x6 present, poor quality of the p10 jach.

Thank you. When you shake the jack there are no distortion, right ?

Yes.

Hi, Even with 12v 1A powers supply the X6 is quite hot. Do you think 12V 2.5A will increase the heat or did you observed any increase in temperatures of X6 ? 

By the way fantastic DAC. Way better than Fiio E10k. 

Seems unlikely the amp will actually draw the 2.5A. And it seems unlikely the power supply will push that current to the amp.

I have recently used this DAC, I have a USB ASIO driver modification for Windows. I have used it to solve sound crackle issues during OS operations while using foobar in a low spec machine.
It has been tested only on win7 32bit on a 1st generation intel atom cpu. I works flawlessly in ASIO mode.
Use at your own risk, backup, use restore points etc.
 
This DAC uses the VIA 1630A chipset: http://www.viatech.com/en/silicon/legacy/audio/vt1630a/
The device id is: %USBAudioDriver.DeviceDesc%=USBAudio10,USB\VID_040D&PID_340B&REV_0010&MI_00
 
Instructions:
 
Download the USB32 driver version 2  (probably better for x64)
 
or
 
http://www.audio-gd.com/USB32driver2014v3.rar  (probably better for 32bit and older CPUs)
 
The second one, 2014v3, I think is better for low spec machines / 32bit (tested). The first includes some x64 ASIO files for better compatibility with x64, atom CPUs might have issues with them.
 
So I suppose 2014v3 for 32bit and driverversion2 for x64 is a good start. But this is not a rule, test them both and keep the best.
 
This driver responds to various devices from www.audio-gd.com that use VIA USB chipsets.
You have to edit some files:
 
You can see the changed lines highlighted in bold. There might be some differences depending on the driver you will choose.

  What do you guys think is better, this or the SMSL M3?

I'm also thinking about getting either the SMSL M3, SMSL SD793-II or the FX-Audio X6 for the HD650. Would love to hear some thoughts about these...

I would not recommend any of these dac amp to use with the HD650.
Will lack strength, dynamics in the sound, recommend the double Schiit Modi + Magni top price in the classified used or Ebay.
X6 is good until HD598 but lacks breath, strength for HD6xx.
I recently sold my dac x6 and I'm hoping to get the Schiit Modi 2 + Vali.

What about for the Superlux 681, wud the X6 or M3 be better? Not planning on upgrading past the 681.

Wow !!
Very good for these 

 

[istinnstudio]

In my opinion this unit sounds better as a line out dac than a headphone amplifier. I think although it sounds clear and detailed, more or less it lacks power on low frequencies. As a standalone dac connected to a tube buffer can sound really good for the price. Very pleased with the sound. This is the way I use it so my quick headphone sound test may be subjective, anyway I prefer the headphone amp sound of Emu 1616m sound card (same chip cs4398, totaly different price level).

I had noticed that some units include different parts especially on capacitors. There are 6 capacitors in the main board, the bigger ones, my unit has 6x330uf 35v while othes might have 390uf 16v or 470uf 16v as advertised. I do not know if those capacitors affect the headphone or line out or both.

 

[GouryellaIV]

How do this sound with a 16 ohm headphones?

 

[freshmind]

I wonder if anyone know what op-amps will be compatible with X6... It has opa2134 in stock.
 
I would like to change and try diffrent opamps to test sound signature in different ways. It can be changed very easly, but I don't know what are the requirements... to work properly.

Are you saying the RCA output on the back is a line out? meaning the volume knob on the front panel will not have effect?
