I don't understand, what is the SU 1.5.1 and SU 1.3.0? Are they newest custom fw from Dimitry who create the SU 1.3.3? AFAIK SU 1.4.0 is the new one..

 

[CoiL]

Maybe SU 1.3.0 is just one of older versions and SU 1.5.1 is just mistake by someone because it is based on original 1.5.1 FW and shows up like this on player info.

 

[dragonsan16]

Oh I see..

 

[cyrano13]

Anyone tried the SU 1.5.1? Is it better than the SU 1.3.3? 

 

[CoiL]

Probably not (if it even is legit newest version?), but depends also lot of personal preferences and gear being used. So far, with all the gear I`ve tried, and hardware upgrades, SU 1.3.3 @ flac only / iir off / cpu default has been superior FW, IMSHO.

It's hard to tell, because link to Dmitry's hub is erased (error 404).

so posted this as a new thread but didn't get any replies so I'll try here:
 
I bought a DX50 a few days ago and straight out of the gate it has been having issues.  Sometimes after 3 minutes of playing, sometimes after 20 or more, the unit will just turn off by itself, even though it is fully charged.  I have the latest firmware and tried doing a factory reset, which didn't fix the problem. 
 
Is this a common problem that you guys have experienced, and if so any fixes?  Is my unit defective and I should return it? 

 

[raulendymion]

Never had such an issue. Have you tried to reset the player or upgrade your firmware?
Try to update firmware again and choose 'Factory reset' in Advanced options.
Maybe it helps.

 

[mrselfdestruct]

hey man, did both of those things.  updated firmware as soon as I got it, then did the Factory Reset.  when that didn't work, did the reset again and still the same problems.
 
the player also has trouble scanning my memory card, occasionally getting only maybe 10% of the files, and then being unable to capture the most recently updated files.

 

[mrselfdestruct]

also there's that very loud pop when the player turns on that is kinda painful on the ears.  is that a thing you experience?

 

[raulendymion]

Nope, pop was silent (I recently switched DX50 for AK100 MkI). IMHO is better to contact service.

Has the card you are using worked on other players? You could try a tag cleaner. There is a Batch Tool on the 1st page of the DX80 thread that works for the DX50. There are instructions for its use with the download. The BT wipes the internal memory and does a clean install. Please try this and see if it resolves your issue.
 
Depending upon the sensitivity of the IEMs there can be a pop on the DX50 when turned on. We advise that you plug in your monitors after the DX50 is turned on.

hey Paul, the card worked totally fine when I used it on my Fiio X3v2, which I had previously.  I'll try the tag cleaner.

 

[mrselfdestruct]

Paul, is there a version of the tag cleaner that would work on my Mac?  
 
It also seems a bit strange for the device to need a wipe the first day it was used, no?

I depends upon what information another dap has placed on the card. Some put coding that some daps do not work with. To clean the card you can use CleanMyDrive2. It is free and works well to get rid of junk that may have accumulated on a card without affecting the music files. There are tag cleaners but I have no specific one that I have used lately.
