I found a photo online of the inside of a Grace design m903.



I am curious as to whether from what you see you can make heads or tails of the headphone amp design (not the DAC) from this image? Besides the slick packaging and nice interface, electronically do you think that this is a decent HF amplifier?


Perhaps there is not enough information to glean from a photo, but if there is; I'd love to hear your thoughts.
