msxmsxThere are some reviews by Chinese audiophiles in Chinese. Since it was released in Mid August. Basically, It has a neutral but little bit warm sound. It has a Triad Power Transformer FP24-500 in side. The amp is not very powerful but enough for lots of headphones. Good for HD600, and One guy even paired it with his HD 800s..................... Magni 2 and Asgard 2 have more powerful but rougher sounds comparing to this one. I sold my Asgard 2 because of its sound signature.
L047Typically speaking, a symmetrical board design is a bad sign, as it is rarely the optimal component layout in terms of signal paths and generation of unintended RF/EMI loops within the amp design itself. I am not an EE, but this is what I have gathered from reading and watching many different in depth board teardowns.

"Forget Aesthetics – It’s apparently hard for some to resist but the optimal layout rarely has everything arranged in neat tidy rows and columns like a spreadsheet. Electrons have no concept of aesthetics but they don’t generally like going further than they need to because someone thought an IC or resistor looked better over there. See the next item."
The entire section is relevant here, but that in particular addresses the layout issue I'm referring to.
