Straight off I think I like the new Zoom Q2HD better than the Olympus LS-20M. Turned on the amp to make sure everything was working. $200 this thing is a steal, IMO
It sounds good, I wasn't warmed up though! I just tested the Zoom w/ the YJM-100. Came out great. The Q2HD has some kind of side-mic that picks up a (user setable) width
The Q2HD is like the new generation of the Q3HD. All the things you wish the Q3 did the Q2 does: manual level control, streaming, better microphone coverage, etc.
