Topping DX5 Review (DAC & HP Amp)

[Phantomuser]

I was one of the 3? folk that reported the update loop problem here.
i bought my Dx5 from Amazon so return was super fast and easy.
I couldn't find another device that did everything quite as well as the dx5 and I like the form factor so I just bought another dx5.
No problem at all so far , its working great.

Topping DX5 Headphone Amp Measurements
Let's measure how quiet the unit is:

Not sure if it appear later on the thread but is there a dashboard for the amplifier section?

Hi, first post, I've been visiting here frequently over the years, great site!

A quick backstory into my decision of finally buying a DAC;
I have been using my trust old Focusrite Saffire 24 Pro audio interface for year, but recently I've been doing some research and want to build a dedicated hifi listening setup which consists of a Tablet+FLAC+DAC+Headphones for better experience, especially when the PC is off and there is minimal room noise from fans, etc, plus it is much more portable.

After researching for a few weeks the Topping DX5 looks like the winner for performance/feature/price ratio, but I am concerned about this "endless update loop" malfunction, 450$ is not cheap for such critical (hardware?) bug.
Before I buy one from Aliexpress with questionable return policy, would you suggest waiting until this bug is officially resolved?

PS.
I have a HiFiMan Sundara 2020 and AT-M50x.

Thank you,
James

I bought it on amazon,
no problems at all, it works and update flawlessy

Hey guys, i got a DX5 yesterday, works fine, much better than my Aune X1S 10th Ed. - but it gets quite warm.. like a lot of warm on the alu case..
I set gain to Low and i manage to use it on like -22 db just fine with my Beyerdynamic DT 900 Pro X.
On the quest to set it proper to generate less heat i got to the setting Auto Power ON/Off setting and here i am a bit confused: is Auto ON the setting to make it enter stand by or Auto OFF .. ?

Unfortunately that doesn't matter because power consumption is not lower in standby.

Uhm is there a technical advantage of me using low gain (with like -20 db volume) instead of high gain (with -30 db volume) with my Beyerdynamic DT 900 Pro X ? Maybe less distortion (that i don't hear anyways at all) ? Thanks !

 

[James-F]

is there a technical advantage of me using low gain

Yes, Low gain has -10db lower noise floor.
The volume control is digital (in the DAC chip) so it doesn't add noise when you turn up the volume, but the headphone amplifier Low/High gain setting is configured by analog components on the PCB which add noise.
Always use the Low gain setting if you don't max the digital volume.
Switch to High gain only if you need more volume than maximum with Low gain, it depends on how power hungry the headphones are.

I set it in DAC mode. I set it to the PO, volume cannot be adjusted. requested to modify it.

Be a little careful not to blow the drivers of your headphones, so use Low Gain.

>>>The power rating is unusually low for a PRO headphone. 30mW continuous and 100mW peak power is kind of asking for blown drivers. With normal home usage this isn’t an issue but in studios headphones can be lying on a desk and when the volume is turned up accidentally you might end up with blown drivers.<<<

So, i am quite newbie at audiophile stuff and i am trying to understand the three filters provided by DX5 so i can choose the best for my ears from the FFT Spectrum of white noise graph. So filter 1 seems to be the less distorsion free ? Then filter 2 and filter 3 is the noisiest ? Am i correct ?
In practical testing i am not sure i can hear any difference with mostly fast music like metal and rock that i listen..

later edit: wow, i have just read some more on this wonderful forum and found very valuable information, i think i understand now what pcm filters do and will test them some more !

Weird that my DX5 came with filter 3 by default.. and that's was what i used mostly but now i am gonna test filter 1 more.

You must have bat ears to hear differences between the three filters

Hey hi, what is the best solution to connect an HD 650 to a DX5?

Hey hi, what is the best solution to connect an HD 650 to a DX5?

Just the 6.35mm plug.
No special requirements.

 

[woodbass]

Juste la prise 6,35 mm.
Pas d'exigences particulières.

Pour le casque le son est plus équilibré sur les prises xlr arrière du dac ?

 

[maxxevv]

For the headphones the sound is more balanced on the rear xlr sockets of the dac?

It has dedicated headphone output. 6.35mm and XLR-4 connectors.

Why do you want to use the XLR output at the rear ? Those are connections to preamps/ amps / active or powered speakers.

 

[woodbass]

Désolé je veux dire

dois-je utiliser un câble "pro xlr" c'est bien pour le dx5 est-ce vraiment une sortie symétrique ?
Ou faut-il simplement utiliser les câbles fournis par le casque hd660 d'origine ?

sorry i mean

should I use a "pro xlr" cable is good for the dx5 is it really a balanced output?
Or do you just have to use the cables provided by the original hd660 headphones?

That is a XLR 4-pin cable to be used for the dedicated headphone output. I have that too.
The DX5 has a dedicated headphone output for that.

The rear XLR outputs are 3-pin for each channel.
Different from what you seem to think how they are supposed to be used.

Addendum:

The original cable provided by Sennheiser for their headphone with 6.35mm connectors are fine.
