I'm very interested.
- 50% of the time it will be a bitbucket behind my V3.
- 40% of the time it will be a bitbucket behind my V3 + SBD.
- 10% of the time it will be Onstage mics > v3 > bitbucket + SBD + ambient mics + patch from a buddy as a comp.
So in my case anyway, that's 4 line-in, 2 via digi-in, and one pair using the Tascam preamps. Even if the preamps are reasonably (on par with a stock UA5/R4/R44/HDP2), I'd be perfectly happy.
At this price point I expect to make some concessions. I don't care if it has a built in Mid/Side decoder. I'd rather record the raw tracks and mix them at home. If it does "digital resampling" like my R4, that doesn't bother me either.
The thing that concerns me is how configurable the inputs are... for instance on my R4, you can't record channels 3&4 alone, you record 4 channels and the front 2 are empty. That's tolerable to some extent especially with an R4's hard drive. But if I had to record 6 blank channels to run SPDIF only, that would not be acceptable to me. I'll need that info before I write a check.
