Review and Measurements of New Topping D50s DAC

[Gradius]

Of course it’s working fine, but it’s a safety concern.
Looks like the ac current connections aren’t protected.

Is very hard to put a finger there, you need to force your way for that.

I would like to unpair the USB socket of the PC from the dac by taking iFi iDefender

Don't waste your money on snake oil. Just take GND out directly from USB connector or cable.

It's not necessary snake oil. iDefender fixed noise issue on my DAC.

What I find is that the D50s sounds exactly the same as the DX3 Pro as long as the Lehmann is between it which is quite a warm colored amp (personal preference).

But (un)surprisingly the D50s and DX3 Pro sound practically the same to my ears (AKM vs ESS).

D50s still wins, they are close, this is why it appears the "same":

I call it snake oil since a single electrical tape can isolate the GND (ground).

It will cost you near nothing (yes, it works), as the other costs the absurd minimum US$ 50 !

did you have to connect additional power to make it work?

to work it works but does not decouple the dac from the pc power supply the ifi is not cheap for the simplicity of the project but it does its job well

My dac is self powered, it worked without additional power. For USB powered dac you need to connect power supply.

I did roll in a Burson V5i-D that I had laying around for review material. The V6 doesn't fit.

Can't say anything useful about it since I didn't do serious A/B listening but I did compare the LME47920 with a Muses 02 I pulled from another DX3 Pro project. The LME47920 was more transparent and well fit for the job. Another sign of good engineering from Topping.

You can find/buy the very same for just $9 bucks. $50 doesn't justify a thing:

A more expensive one (if you like to burn $$$):

ok I like this very much also for the price is there the version with separate power supply like ifi?

gradius I looked for some reviews and evaluations and in fact you are right you also the various usb purifiers are useless just a good linear power supply and a modified cable. I wanted to try to make me a cable with separate power supply but my only doubt is the shielding of the cable must also be interrupted and left connected only from the PC side?

Well, I did got a much better USB cable quality.

I didn't noticed a difference with GND on, and GND off the cable really, more like a placebo effect. I mentioned that here:

I can tell a good dedicated power supply and cable will do just fine.

I know its not the place to post it, but I had the Topping D50s power plugged using a Apple charger. Now Im using a external battery between the DAC and the apple charger.
I feel like the soundstage opened and corners are rounder, treble is much less harsh. I know lots of you will call me insane, but that's what I feel.
My setup is Volumio (raspberry pi4) --> USB cable (Wireworld Ultraviolet)--> Topping D50s --> Marantz PM8006--> Dali Oberon 3 speakers. I use the Audirvana in a MacBook Pro to play songs.

This is an audio science forum, sir.

Can you give me the link for Thesycon USB drivers for Topping? Thank you

No worries.

I got mine today.. it's just WOW, the old SMSL M8a was ok but this is really another level.. Impressive DAC

It's even better with Dolby Atmos.
