That's three very different results. To my ears the MicroTrack sounds sligh=
tly
better, but it also sounds like it might have some roll-off on the low
frequencies? Am I listening for the right thing? The noise there sounds lik=
e
it might be supposed to be there, i.e. distant ambient rumble from
traffic/city. Or is that actually noise introduced by the equipment?

Nice page - I'll need to study that a bit to comprehend it fully. But rugge=
d
sounds good to me so I might settle on the Tascam HD-P2.
Anyone recommend a fast source for a recorder like this in the UK? I'm
familiar with music type suppliers (e.g. Turnkey) so I'll check those too.
Regards,
Kevin
