fmaderjr, yeah, no sweat, the Sony M10 is still the better and best buy of them all out there so far and especially now that its price has dropped lower! The Sony is also better built but a bit larger and bulkier than the Roland R-05. As for the preamp noise levels and sound quality characteristics, I cannot really say right now as I've not had any experience with them yet to say conclusively. Only time will tell yes. From what I know now owning all these units, the Sony PCM-M10 is the best designed and offers more features. Unless later other folks measure the R-05 noise levels and dynamic range capabilities and it turns out better than the Sony M10, right now I think they are about equal in that category. But like I said, considering features, build quality, price and all, the Sony PCM-M10 is IT ! The R-05 is very close. I have no idea about the R-09HR as I skipped that generation. I have the R-09 of course, but we all know that one has a noisey mic preamp and is only good for recording loud concerts where preamp noise is buried and a non-issue.
