The problem is common to most DACs that can play MQA. However, the degree of click depends on the audio player and DAC used.Hi, i am have issue with MQA tracks (on TIDAL and Foobar2000), then start play or scroll track it make 'clicks' then change mode from PCM to MQA, same as here https://audiosciencereview.com/foru...dac-and-headphone-amplifier.24341/post-902276
this bug or feature?)
valve/transistor just increase thd to mimic the sound of tube, to -50dB.New firmware 1.38, wich adds also
a "sound mode" option valve or transistor,
and a balance option.
Upgrade went flawless
No documentation about these new features
and the "dither" one in previous firmware.
Hopefully an eq feature on next updates ?
I can't hear any difference between sound modes !!
attached an oscilloscope and spectrum analyzer, can't see any difference !
defective unitI received my DX5 from Amazon 3 days ago and tested it immediately and found that there were many problems with the DX5's operation. None of PCM, DSD, MQA works properly like the E50 and DX3 Pro + I have used so far.
Pop noise caused by switching to songs with different sample rates or switching songs between DSD and PCM. Occurrence of sound interruption or pop noise that occurs several times at the start of MQA playback. In addition, the volume may suddenly drop extremely and no sound may be output from the left CH. The sound quality is good, but I am not in a state where I can listen to music with peace of mind.
I immediately learned about the new firmware V1.38 and installed it in anticipation, but nothing improved. I will investigate the symptoms a little more and then return it to Amazon.
you need chmod +xApologies if this has been covered before, but I just bought this on Amazon and tried to upgrade the firmware to the new 1.3.8. Unfortunately I'm on a Macbook Pro M1 Max, and when I try to run the mac application to do the update, it says: The application "Topping USB DFU" can't be opened.
It's not a security/permissions issue, the file doesn't say "This application can't be trusted" like most firmware update tools (where you then go and grant it permission). This just straight-up won't run. I assume this is because the firmware updater is written for Intel macs, and there is no native firmware updater for ARM based Macs.
Can anyone confirm this?
Also in the 1.38 firmware zip file, the actual firmware bin is v 1.3.7, which is weird.
Seems like I can't update firmware on an M1-based macbook?
as long as the desired level could be reached, there's zero benefits for hp outs to be internally balanced.@amirm :
Thank you for making me aware of the Topping devices.
I searched the Shenzeaudio site but cannot get a definitive clarification to the question :
- is there a Topping DAC (with the usual digital ins : USB/SPDIF/BT LDAC) which also has a true Balanced headphone amp outputs ?
They have some DACs featuring 4pin XLR and/or 4.4mm headphone output sockets which are traditionally for Balanced headphones.
Sadly, Topping do a very poor job at making it clear in their product description/specs whether the Headphone amp is truly Balanced or not.
Most seem to be just Single Ended amps with XLR or 4.4mm sockets for convenience only.
Being as knowledagble as you are in the Topping products :
Can you please help clarify this and point us to the specific Topping products which have a true Balanced Headphone amplifier (and not just physical output sockets which 'look' like they may be Balanced) ?
Failing that :
Could you suggest such a DAC/HPA device which is in the class of Topping as far as spec and price range ?
Thank you very much.
