Hello Rob/Phil/others,
Have a Sennheiser ME-66, a 1" diaphragm MXL V63M Condensor (for
ambience and voice over), some cheap lavs (to be upgraded)
I connected the ME-66 to one leg of a Y-adaptor in recorder's mic-
in...placed mic under pillows. At highest record level, meter showed
20dB on mic'd channel... -35dB on the open channel (recorder's self
noise).
Headphone monitoring: mic'd channel 'sounded' 2x louder and of
a 'rougher' nature ...like rain on a window versus the Sony's
smooth 'rain on a solid roof'.
So I need to be willing to shell out for very quiet mics before
expecting magic from super-quiet external pre-amps ???
...darn! I just had my eye on a snazzy Sign Video ENG-44
mixer! ...unnecessary candy???
You're quickly getting my thinking straightened out, thank you!
(will restructure my needs and look for suggestions of quiet mic
capsules...for parabolic)

Manufacturer doesn't even list the product on their site anymore. Too
fishy.

mic pre's in my Sony PCM D50 ...though their circuit noise has a
smooth far off ocean quality, it is very much there at high recording
settings. Clean line levels would bump up that S/N ratio. That is why
I am returning a $300 (overpriced! ) BeachTek dual phantom xlr box
because it is passive ...no amplification. I just want clean
amplification ...seems that paying extra mostly gets you extra non
essential fluff on these devices. Until you pay enough for marketing
fluff AND good circuit (Shure's or Sound Designs) the important specs
just aren't that great. I'd be happy with a clean circuit in a rusty
can ...hobbyists build such circuits fairly cheap. This new recorder
I have takes care of the extras like limiting tremendously well as it
simultaneously records lower level tracks and instantly uses them if
things get loud.
