+1 that SINAD is not the most important thing to look for. synergy between cans and amp is more important.
both A2 and A3 should have much better bass than the microstreamer (which is likely a chip amp based design given its tiny size). but I think the A2 may be a better match for you as the A3 also has a bit brighter top end vs A2. Consider buying the A2 from Schiit directly on www.schiit.com/b-stocks as these have the full 5 year warranty (lower risk when using your nicer, more-expensive headphones versus a used unit with unknown usage / age). use a short (0.5m or less) RCA cable between the DAC and amplifier.
