Ozfly, depends on the school of thought, but I believe substance is defined as the core and essence the extension of that core (mode). Substance is not subject to change while essence will depending on a number of extended attributes. As such, essence does not exist without substance. I guess in audio terms, substance would be the recording, it's essence (what we hear) being extended by (our equipments) applicable attributes. What does this all mean, I have no idea. Actually, an intersting side note, it was "audiophilism" that got me off the lost lands of philosophy. Or rather, it was philosophy that lead me here. Not sure if I'm better off, but I'm having a heck of a time.
