Just a remark on this DAC.

  • They state MQA, but actual using it is a different balgame.
  • With a vast majority of MQA tracks, this DAC fails. It can’t perform the full encoding and start switching MQA off/on/off/…
  • They have decide that it’s nice to have the LCD screen on all time, which results in a LCD burn in.
  • Support is not on par. Filed complaints more than a year ago. On the MQA part => nothing they can do. On LCD part => Silence. (Raised a support request again)

Carefull with that one connected to raspberry pi with volumio.
I’ve managed to burn one of the clocks three times by playing tracks of 44,1 or multiples followed by 48 or multiples (or vice-versa). The first times it occurs, it just makes some noise, and a power cycle resets it. But eventually it would stop working.
A pitty, as I loved the sound, specs and form factor.
Support from the retailer was good, they changed or repaired the unit every time, until I’ve decided that was enough and trade it for another model.

With the Pre Box S2 Digital, i use a SPDIF Cabel. I bought a Hifiberry Digi2 Pro.

Who updates the TOC? It appears a bit out of date compared to what’s been listed.
I know two of mine aren’t listed int he TOC.

Nobody, the community member who used to do this does not visit the forum very often anymore.

Updated the list. To be honest, this will happen occasionally as it’s a very time consuming thing to do.

Yes, I figured it’s time consuming. Easy enough to search :slight_smile:

Is there really no hardware volume mixer with Topping E50… that sounds weird…

Sorry:

I was surprised about this when I first heard about it over a year ago. It’s a side affect of supporting MQA and it applies to a lot of MQA DACs.
