E-600 Fully Balanced Amplifier (Chinese) warning

Did they fix this thing in the end?

I issued a warning after discovering some of these units had a flaw with reversed or crossed polarity in the 4-pin. If you use the 2 xlr’s with an adapter it will work balanced.

Ok, so i completely missed your warning (I havent been getting updates from this forum for some reason). So all I need is to get rca to xlr adapters to make everything work?

I don’t even know how I would go about checking for a reversed or crossed polarity. Can you enlighten be?

So is it actually balanced in and out or not? Any new updates on it?

Hello.

My first post here. Also interested in the latest assessment: has the manufacturer perhaps addressed the issues mentioned here, is the amp really balanced in and out, the one here for example: https://www.aliexpress.com/i/33040446809.html ? There is also a version by Audiophonics (https://www.audiophonics.fr/en/sedentary-headphone-amplifier/audiophonics-ha-b6120-full-balanced-headphone-amplifier-tpa6120-muses8920-p-14573.html), anyone had experience with them (perhaps better quality control is to be expected from them? or is it just wishful thinking?)

Thanks in advance!
