Sorry for posting this here, but as a new member I cannot post it in the headphone amps section. Also, I'm not a circuits and soldering type of person. Just a long time hi-fi user.

FX-Audio recently released an updated version of the DAC X6 and I have two questions. BTW, I'm not referring to the X7. This update is called the M6.


FIND IT HERE:

AND HERE:
https://www.aliexpress.com/item/FX-...bf-4bf4-a6f5-0cd5986ac974&transAbTest=ae803_4

KEY Chips used in the X6 are:

DAC chipsets: CS8416, CS4398, OPA213

• Headphone amplifier chipsets: OP275+TPA6120

KEY Chips used in the new M6 are:

SA9023 + CS8422 + AK4452VN + OPA2134 + MAX9722

-----------------

QUESTION 1: Are the chips use in the new M6 a true and beneficial improvement as to performance and/or durability?

QUESTION 2: The older X6 uses a 12v 1a (or higher) standard power supply. For the M6 they are using a USB wall adapter that is 5v 1a and a mini USB connection on the rear of the DAC. Again, I have zero technical background so I would like to know if this USB wall plug at only 5v should be concerning as to performance and/or durability?

Thank you for any opinions you can offer on these two issues.
