Current draw is dictate by the device, not by the charger. So it is a pure myth if you use higher power charger it will damage the device. Fast charging is also dictate by the device, not the charger.

Hmm I live in Korea and actually called iRiver service number, and that's what they've told me. Recommended using 5v below 2A.

I will post my charging measurement in my review later. No matter high the charger current, AK70 draws less than 1A, only around 900 mA when battery is empty. I will try again using older USB charger, non fast charging, 2A output, and will observe. Btw, highest 5V charger this days only rated around 2.4 A, and theoretically should be save to use. But since AK told you so, I will give it a try. Though as an electronic engineer, I'm confused of the reason behind that advise. Thanks!

AK has indeed said to not use chargers over 2A

It's not the DAPs fault, it's the HUGO I'm afraid. It can't receive DSD unless you put it in the proper container. If I remember well

Works fine with my Samsung S4 - S6 edge + via USB OTG using the same files via micro SD card
 
Phone outputs DSD (DoP) no problem and Hugo's light turns white meaning it reads DSD fine so I highly doubt that it's Hugo's fault.

  The DPX1 worked flawlessly on the Hugo but usb output was limited to 192/24 I believe when I tried some DSD files. 

 
Nope. DP-X1 can stream DSD to most DACs I tried. I have Mojo, will try later. But I think I tried before, no issue streaming DSD from DP-X1 to Mojo. But haven't tried with Hugo.

Any idea what's the reason?

If I remember well the communication by Alex just said it could damage your player. No details.

Must be the settings my friend hand his DPX1 during the time we tested it. Can you try it with the Mojo. He has a mojo but I think he he hasn't been able to make it output dsd via USB yet.
 
If it works for you what settings did you have.
 
Only iffy thing about the DPX1 is the 2.5mm balance port that falls off...my friend's unit still has the same gap around the port which makes me try to get the AK70

Works with Mojo. Make sure that USB settings are at DoP on your player and not PCM.

That is with the new FW, correct?

i will try later at home. Only brought DP-X1 to office now, Mojo left at home.
In my DP-X1, I set the DSD Output Format to DoP as shown below.

My DP-X1 is up to date.
Onkyo at one time updated the firmware with the release note that they fixed a bug related to USB DAC connection, so depending on how old your firmware is by "original" (some of the newer batch may have newer firmware) I would say there's a possibility that you may have the pre-fixed version.

FYI, just measured AK70 maximum play time.
 
Testing methodology:
Headphone output set to : 100 mV rms (0dB sine wave) - Volume at 123
Load : 16 ohms IEM
Screen off most of the time.
 
Result: 9:43' (9 hours 43 minutes)

thanks for all the comments guys...well since I don't want to be too OT in the AK70 thread...I hope that the pops, ticks and stutters playing DSD with the AK70 get addressed
