Hi there, watching and reading some reviews about the Topping DX3 Pro+ I noticed several comments saying the older
Topping DX3 Pro is quite better, but no one explained why. Could someone please shed some light on this? From the spec sheets I'm not knowledgeable enough to tell a real difference. Thanks a lot!

I am only guessing here, but I guess it's either due to the different DAC chip used on the Pro+ and/or the difference in output impedance?
