WOW, I guess that usb cable was soaked in snake oil for at least 3 days. Mate I bet you won’t hear any difference if someone changes that cable without you knowing it...

What?! And how do you actually think this would happen? Don't get fooled by the snake oil vodoo magic - there's nothing to "break-in" inside. Electronic digital circuits don't "break-in", with time your brain just gets used to the sound you hear from the device and you start to think it sounds...

what about the amps? what are the power ratings? Can it drive high impedance headphones?

Thank you very much for your answer and the link. I'm actually from Europe, so this offer is very interesting. P.S. It's a tough choice now :) I really like the looks of the Topping stacks, but also daart canary has good reviews too.

I'm rather new to this, so pardon me if the question has been asked. I'm looking at getting a DAC+AMP combo (Or maybe a single unit). So far I liked the looks of these D30 and the A30, but there are several other offering with the similar price tag, like the Sabre ES9018K2M based yulong daart...
