Looks like that PCB was laid out to look pretty, not to optimize performance. I cringe at all these symmetrical layouts with their components in neat rows and columns. This is almost never optimal for the circuit performance, and raises more questions, in my mind, as to the design priority.
More detailed measurements and a better, more complete set of specs could go a long way to all these concerns. If the design truly has merit, it should be apparent in it's quantifiable performance.
The circuit is a symmetrical, dual-differential design, so yes, that will be reflected in the board layout. Also, I'm sure the paralleled output transistors are easy to spot. We'll publish a larger set of specs however MD has a standard list that they use for amplifiers. Most likely this amp will end up measured by a 3rd party as well. Innerfidelity has measured both our Pico Power and GS-X mk2 amplifiers and both were top in class in measurements.
