The long wait is finally over. New Gustard X16 DAC and Topping A90 headphone amp arrived today from ShenzhenAudio in China.

Glad to know that the balanced headphone cable from Audiophile Ninja works (had no easy way of testing it before now).

So far so good. Not much to say that hasn't already been said elsewhere, although it is worth noting that it has plenty of power in low gain for the Hifiman Sundara cans using balanced headphone cable.

Oh, and it's surprising how much heavier the X16 is vs the A90. You'd think that because the A90 is an amp that it would be heavier, but that's not the case.

Worth the almost $900? You can certainly get a stack with plenty of power, Bluetooth, and USB inputs for less, but these are both high quality units. So far I'm pretty pleased with the purchase.

That's still an endgame stack. In some ways the A30pro is better than the A90, especially for single ended headphones.
I see. Still a noobie audiophile person at the moment. Nice to know it's a good stack I'm thinking about.
I'm going to get HD 660S headset then the Topping stack. Purely for desktop computer use.
Separate components needed as in a few months I am going to purchase a turntable, to listen to vinyl through headphones.
