Hi project86, did you have a chance to test:
1) MA8 with optional balanced amp card;
2) MA8 with MA9 amp card;
3) Colorfly C4Pro (priced slightly higher than MA8)?
Very interested in your opinion and comparison versus stock MA8.
Both would likely be pretty nice. I'd probably choose the MA8 for my AS-1b, since it has a more lit up top end. Which is helpful on the somewhat dark AS-1 series. Not sure about the AS-2 though - you may do better with the smoother 960.
