THE ART OF RECORDING
Part 1 - Part 2 - Part 3 - Part 4
Part 3. ANALOGUE TO DIGITAL CONVERTER COMPARISON
Procedure:
In all cases except for the KORG MR1000, SOUND DEVICES SD744T and METRIC HALO[used with an Apple Laptop], I fed the outputs of the Stellavox SM8 to the A-D converter inputs [using my ENOSIS cables in all cases], then the SPDIF output of the A-D's was fed into the BNC SPDIF input of the Sound Devices 744T.
Absolute Reference:
For those of you who aren't used to the sound of a "holographic" recording, I have included some short samples of the legendary work of Bob Fine [Mercury Recordings] who was using essentially an AB set up wiith a middle "mono" channel. He was using the Telefunken ELAM 251s [AKG C12's]. His contemporaries Lewis Leyton [RCA RED SEAL] and Ken Wilkinson [DECCA] achieved similar results using the legendary Neumann M50s.

The Concert:
BENAUD TRIO [violin, cello & piano] perform LED ZEPPELIN'S "STAIRWAY TO HEAVEN".
You can view a track from this concert to see how the mics/musicians were lined up. I was using Neumann M150s in AB and TLM50s in XY: http://www.reel2reel.tv/SCREENERS_WMV/__benaud_stairway-1a.wmv
Listen to the huge "weight" in the sound and the "dimensionality" or 3D realism of the instruments. To me this is the key. And this is the problem with all the digital location recorders I've tried. In general, they knock out the bottom octave [or "bloom"] and flatten the soundstage. Music through them sounds artificial and dry.
