I was one of the first tapers that used an MR-1. I recorded over 70 shows with
my unit before i sold it. The sound is great, very transparent and clear.
My issues:
hard drive based, will skip if bumped into or dropped.
system software not perfected, some freezes
needs pre in front for quiet stuff, if you push the MR-1's gain, it will add horrible noise
internal battery sucks, only 1.5 hours with full charge
problems when connecting external battery source, unit does
not automatically switch over to external power, sometimes it just
shuts off......this was the deal breaker for me
ymmv
