While I know the 722 is a giant step forward in the tapers evolution I still have yet to hear any SMOKIN' tapes from them. A bunch of really nice ones but none that just make you want to sell all your shit to buy one. I feel like the 722/744/MicroTracker/etc. are really just the first batch of new recorders to hit the market. The 24 bit market is still in its infancy. Hold on to what you have. Its a proven winner, the 722 isn't yet.
