Hi Tony--
The main strengths of the Rode NT1A's are their
extremely low "self-noise" and high output. Used
in conjunction with a recorder that also has
low-noise/high-gain, like the HiMD's, one can
record ambience with spatial clarity that would
have cost several thousands 5-6 years ago.
However, for robust sounds like music and voice--
or situations in which your recorder's gain is
set about 1/2 way-- one would probably have to
prefer the _sound quality_ of the Rode mics over
that of the 4033's to justify the change. "Good
sound quality" depends on many things, but most
people can readily hear the noise differences
like hiss. If you are experiencing noise with
the 4033's (and they do have about 20dBA more
self-noise and also less output), then an A/B
comparison with a Rode could prove to be
interesting.

To use condenser mics with the HiMD recorders,
one also needs portable phantom power supply like
the Rolls PB224 or an Art Phantom II ($40-70).
Then use a "Y" cable adapter like this to connect
the phantom supply to the HiMD's 1/8" stereo mic
input: http://tinyurl.com/cm5qm. The ECM 717
will power on the 910's mic jack but it may not
be your first choice after you compare it to the
WL-183's wired for the mic jack:
http://tinyurl.com/8gv8o. The Tram TR-50 is
among the better lavs, but the 183's lower
self-noise and higher output has people recording
ambience with them/ finding them a bit more
versatile. Note that the WL-183's do "bottom out"
with very loud sounds though.

Sam, you might be referring to the Crown stereo
"SASS" fixture. I'm very impressed with the
stereo and low Hz imaging of this design as well.
Some people have been purchasing a SASS fixture
separately from Crown @~$100 and fitting it with
lower noise Omni-directional mics like AT3032's
or expensive Sennheiser MKH-20's. If people are
interested in some of the more budget DIY rigs
field recordists are building-up, contact me
off-list and I'll assemble some links. Best, Rob
D.
