In playing the Studer plug-in video, am I an aberration in much preferring the unprocessed sound?
I don't think so. The plug-in emulates the sound of a Studer multi-track tape recorder. It adds coloration to the digital recording to make it sound as if it was recorded on the Studer, with the gentle compression of tape saturation, various distortions, etc. It is a nice, fat, warm sound, capturing the artifacts of recording to tape.
To me, it is like the artifacts, compression, etc. necessarily introduced when cutting to vinyl. It is a nice which and I appreciate why some are really drawn to it.
I prefer the clean digital recording without processing, but fully understand why others may opine otherwise. (The comparison is unfair as the processed version is a lot louder - louder is always compelling, to which the loudness wars attest.)
Diana Krall recordings emply a great deal of compression, especially on the vocal. But few would like the sound of an uncompressed close-mic’s vocal; it’s raw and brutal. To me what would be much better would be to record her a couple of feet from a superb ribbon or a flattering tube mic - think the sound of Sinatra.
