This explains a lot for me, and it's definitely something to think about.
Thanks for the explanations/examples. I really liked the R1 - not a lot of what you call floor noise, what I used to call hiss, or recorder noise. I like that very much. Wonder how the R09 will be.

And I like the way the R-1 sounds. Does it do stereo? Is it overall decent
as far as quality? Is it portable?

Yes, stereo. In fact, recording in mono isn't even an option, except for only recording from the left channel. It still outputs to stereo. Kinda dumb, really.

The r1 is portable, however, it's also just recently been discontinued
by Roland, to be replaced by the R09, which may or may not lose. They've
either just been shipped or haven't shipped yet, thus, we don't know

I personally think the mic preamp in the r1 could be a bit better,
although it's certainly nicer than anything I've seen in a Sony minidisc
The signal-to-noise ratio of the line-in is pretty low, definitely lower
than the mic preamp, but not to those scary high standards set by sound
devices and such.
The thing about the r1's line in is that no matter how high you turn the
input level, the noise floor never seems to get any higher (definitely
not the case with the mic preamp), which means
theoretically if your output signal is clean enough, you could get away
with quite a hot signal at a relatively low input level, and thus achieve maximum snr given the
specifications of the unit.
Even if you have to crank the input level a bit, the biggest factor will
be how low the initial noise floor of the device you're connecting it to
happens to be, given that it is above the noise floor of the device
you're recording with.

As for high quality portable tape machines, all I have to say is
"Merantz". Probably not overall practical in terms of price vs.
maintenance, but as far as I know, some are still around.

Given that cassette media were never meant to be used for as much as it was, some of the stuff they've come up with has been very
scary clean even to today's standards.

For example, there is a file on www.quietamerican.org that someone
recorded in a theatre in Israel during an air raid. He used some merantz
portable tape deck and an ev 635-a omni-directional dynamic, and there
wasn't a lot of noise in the theatre -- just a quiet radio giving
instructions, a very faint air raid siren, and someone putting duck tape
over the windows, so you could get a pretty good idea of the noise
floor. If not for the occasional tape drop-outs, I wouldn't have thought
it was cassette, especially given the portable status of said recording.

I think, though I could be wrong, that super-scope had some offiliation
with Merantz? I know they made some nice portable field stuff too,
although this is mostly all before my time.
