Another variable to consider is Chris Church's modification of the R-09's internal mics. I haven't had this done to mine, but I'm thinking about it. I'd be surprised if the resulting sound quality isn't very good.
Being a Church mod, I'm 100% sure the sound quality must be very good

. I'm also thinking about. The only thing that makes think more is that the final product does not look exactly awesome

. And I don't think the whole think could be reversed to it's original condition.
But this is pretty much a matter of personal taste

. It's a nice option anyway.
