Happily, as result of a youthful indescretion, I have a LUNATEC V-3 in
need of a flash memory recorder.

If I am going to use the recorder for 16 bit 44.1 or 48 kHz sampling,
is there any SONIC difference between a less expensive (MicroTrack) as
compared with a more costly (PMD670), or other, recorder?

I was looking at the Sound Design 722 untill I read on their site that
even the $2300+ 722 would benefit from a better preamp -- of course
they were recommending one of their own products, but as I already have
the LUNATEC...

The recorder wouldn't use any on board AD or DA processing,
preamplification etc.

Any suggestions, observations appreciated,

TIA, alan
