I suppose you have a good point there. Good part is thought, that you can mod it without loosing warranty. And that makes a difference. I have sent my amp8 to get moded and it worked out well.I had a DX300 it was big ole POS, sent it back. You will like the SE200 better. What a lot of people dont realize is that DAP's with swappable amps have scaled down parts in them. They have to sacrifice part quality to cram all that stuff in a swappable card, smaller caps for example, it is not worth the sound quality loss IMO. Only cool thing about them is a dedicated line out card, but still, I would rather have the room for larger components. That is why the SE180 looks cool, but in reality is a really bad idea. Lots of sacrifices have to be made to keep those cards small enough.
But yeh if size is limitation there is only so much you stuff in to that module.
Though seeing how se200 is not that big with 2 seperate circuits, must have some sacrifices too. The only way to find out really is wait to see what future modules or mods can achieve. To compare dx300 to se200
