mmm....just got this message from AK via FB Messenger:
Since we don't have enough information regarding specs of both AMPs mentioned above, we are unable to guarantee whether it will be compatible with AK70 or not. So it would be better to ask those AMP's manufacturers to check its compatibility. Thank you.
So, what amp did they test with the AK 70's USB out before manufacture?? l mean, there aren't a lot of amp or amp/Dacs that accepts USB Audio. WA8, CDM, Aurender Flow, the Chords, iFi iDSD Micro, CEntrance HifiM8 are the more prominent examples.................................lol! At the very least, they should disclose in the AK 70's product page or documentation the amps that are USB Digital out- compatible with their product. It's just common sense and goes a long way in empowering their potential customers in making an informed decision. I mean, this is their debut product for USB Digital Out!
I'm glad that WA8 is compatible with the AK70, out-of-the-box.
