I still have the MSR16 Dolby version. It arrived via ebay with the Dolby not functioning, and after a few hundred dollars of a highly recommended TASCAM tech, no luck still. He believes the problem may be in the chip as he replaced some (capacitors??) or something on the boards. Anyway, the Dolby version, if you do a search, seems to have some intermittent problems...not every machine I'm sure, but that is what I can offer. I haven't given up on the MSR, it's just on the shelf until I decide to give it a second chance some day and maybe purchase some outboard NR units for it.
I did post some raw clips of the MSR recording drums vs. my HD24 drums at
www.soundclick.com if you want to hear. There are other clips there, but the MSR and HD24 are clearly labeled. Search artist for Dale O'Brien and you'll find them. MSR tracks were a newbie attempt so the levels may be off, and the machine was calibrated by the tech for GP9 tape and that is what was used.
For what it is worth, I hear a lot of people saying good things about this machine. Also, have you considered the MS16 1" 16 track?
EDIT: I haven't listened to them for awhile but just did...if you do, the MSR samples 1 and 2 I believe I was indulging in some red wine both separate times I recorded the tracks. I think I was making the newbie mistake mentioned above of hitting the tape too hard, as well. Anyway, should give you an idea, if you ignore the playing and shitty recording technique, of a ballpark sound and "charactor" of an MSR, nothing fancy on outboard injected.
