Just got quoted ~$490 with late November expected arrival.
Not likely D50 has even close to quality mic pre in D1.
Specs give
NO preamp mic input data,
ONLY LINE input-to-line output specs of 93 dB S/N, which seems not so great. but no reference at what output level or if weighted measurements, so too vague to know for certain the meaning of 93 dB.
So far, compact, long 12 hours running time on 4 AA, track mark/split ability, and classy refined easy manual controls is best news.
Expect the nice attached mics makes this a good 'all-in-one-deck' for on-the-spot good quality recording deck for interview, sound designers, musicians, those tapers looking for a low profile, affordable deck that does at least okay for starters or as a backup unit.
Definitely good news for those looking for that elusive moderate cost, small size 24/96K 'bit-bucket' alternative to the Microtrack.
