On My New Topping DX3 Pro

Finally, folks, the long wait was over and my DX3 Pro black unit came in this morning, Jan 4. I ordered it on Dec 18 from eBay topssale seller for $193.59 total.

Nice form factor and feel! I have set it up with my laptop (Windows 10, MusicBee player with ASIO) over USB connection and played some lossless files with varying sample rates. I noticed two things that bother me and would like to consult fellow DX3 Pro owners here:

1. Does the remote come with the battery? Mine doesn't.

2. I installed the driver v4.47.0, as well as the firmware v1.04. In my understanding, the update should fix the clicking noise from the unit each time one switches playing files with different sample rates, e.g., from PCM 44.1 kHz one to 96 kHz one. But this clicking noise issue remains after I applied the firmware v1.04. Have I missed something here?

Thanks!!

It's on Massdrop again for $174.95. I ordered one when they first appeared and it was lost in shipping. Since then I see reports of issues with units failing etc so I'm pretty leery of buying again. Especially since you have to send them back to China for support.
Would love it if JDS labs made a DAC to match the Atom Amp.

EL DAC performs damn well. you just don't care for the size difference?

Hi all,
I also received a DX3pro kit and testing it since a couple of days... sounds good (at leas as good to my current DAC)...
but it could be much better if i could remove my preamp and connect the DX3pro straight to the Amp..
and then come the problems !!!
I someone press the LINE OUT button or double click on the volume button, then the DX3Pro switch preamp mode to DAC mode and the full signal (at -0.0dB) is sent to the Amp...i let you imagine the consequences....

apparently i'm not the only one to report this issue...

what can we do to make TOPPING sending the Alternative firmware to fix this "bug" for the one who want to use it as preamp ?

Just use the remote.

The little micro that handles the user interface is apparently not field upgradable according to Topping. I use the remote as noted and have not had this happen to me.

Hi all,
to [U]ascorbyl[/U] and [U]amirm[/U],: I do confirm you : when your DX3pro is in preamp mode ("DAC" lighted on the screen, and knob allowing to set the output volume), if you Press "LINE OUT" on your remote controller, the DX3pro switch in DAC mode ("DAC" lighted, but knob can't change the volume anymore) and the signal is sent full (-0.0dB) in the RCA output. If you AMP is connected straight on the RCAs i let you imagine... ;-)
Warning guys... do use your DX3pro as a preamp....

When I press Line Out once on the remote, it is in variable output mode so no issues. I drive my active NHT monitors that way and so far, I have not had an instance of it going full volume (which requires a second press on the remote).

I can say from experience, if you do it once, you won't do it again. :D

I do agree that a firmware update to change this to perhaps a long hold on the Line Out button would be a good idea. Especially when you are in the learning mode on a new devices, your testing functions and pressing buttons quite a bit. I knew about it and still managed to do it. Fortunately my powered monitors were not at full tilt but certainly scared the crap out of everyone in the room. :oops:

It's on Massdrop again for $174.95. I requested one when they previously showed up and it was lost in transportation. From that point forward I see reports of issues with units falling flat and so forth so I'm quite suspicious of purchasing once more. Particularly since you need to send them back to China for help.

Would love it if JDS labs made a DAC to coordinate the Atom Amp.
