Topping D50 III Balanced DAC with EQ Review

[johny_2000]

Hi folks,

I've been using the Topping as a generator for my tests, and it suddenly refused to output signal from RCA or TRS outputs when fed by my computer.
I installed the latest driver, ensure RCA+TRS outputs are active, it is pre mode and not muted. I tried with different USB cables too.
Strangely enough, the computer sees it and when I change the sampling rate, it synchronizes correctly but it will not output any signal.
I'm using REW software, as always, and when connecting an SMSL PS200 to the computer instead of the D50III, no issue.
Clues?

Thank you

Have you tried performing a factory reset? I've had to do that several times over the couple of years I've been using it, as my device would go into a lethargic state and wouldn't work until I performed a reset.

Yep, I forgot to mention that I tried, but no success.

Yep, I forgot to mention that is tried that too, but no success.

Did you opened it?
Sometimes these have some smd self-healing (or not) fuses (don't know about Topping though)

They appear to work at PC when they go bad but the rest of the board doesn't.

I agree with this. Open the device and look for SMD fuses or zero-ohm resistors connected in series with the power supply lines of the output stages.

Do you run linux on your computer?

@TOPPING DAC that has this kind of performance but also supports aptx Lossless, when? Fiio already has the BTR17.

Home Assistant Lovelace + Zigbee2MQTT IR Script for Full Control of the Topping D50 III DAC

Hi everyone,

I wanted to share a clean, fully functional Home Assistant Lovelace setup that gives complete button-by-button control of my Topping D50 III DAC using a cheap Zigbee Tuya IR blaster (the one that appears as `IR_Tuya` in Zigbee2MQTT).

This works perfectly and lets me integrate the D50 III into automations, dashboards on tablets/phones, etc.

Here's what the Lovelace card looks like (exact replica of the remote layout):

Lovelace YAML (vertical-stack with three grids):

      topic: zigbee2mqtt/IR_Tuya/set   # ← CHANGE THIS to match your own IR blaster entity in Z2M
      payload: "{\"ir_code_to_send\": \"{{ ir_codes[command] }}\"}"
description: ""

How to use:

• Create the script first (the IR codes are already captured and tested).
• Create the Lovelace cards (copy paste the YAML).
• Point your Tuya IR blaster or another similar device at the DAC’s IR receiver (mine is about 1.5 m away, works flawlessly every time).

This gives you every function the original remote has: power, mute, volume ±, input selection via left/right/OK or direct C1/C2, FIR filter, Line Out toggle, Auto mode, and brightness.

If you run Home Assistant + Zigbee2MQTT (or any MQTT-based IR blaster), this is a very cheap and reliable way to get full remote control.


Hope this helps anyone who wants tight integration with the excellent D50 III!

Cheers,
