Looks like a nice upgrade to the DR-1:
DR-2d: 24/96, two AA batteries. recessed, stationary on-board mics, dual recording mode.
DR-1: 24/48, proprietary lithium battery, sliding on-board mics, no dual recording mode.
I love the DR-1 so far. 2 years running and countless shows, and still using the original lithium battery. AA's are king for festies though. Sliding mics are a tiny nuisance when taping down the line-in connection. 24/96 capability and dual recording mode is a big huge plus.
I'm wondering if the sound quality is the same. Will have to wait for Wingfield's samples. The DR-1's Mic-in is superior to the Line-in, for its warm butter smooth. Looking for an upgrade to the Line-in sound. If it is upgraded to the Mic-in sound, I might make the jump to this in `10.
