ΔM

US mastering engineer, Has worked at Disc Makers, NJ.
Was a contributing editor for the magazine "Modern Recording" in the late 70s and early 80s.

He is often identified by "F/W ΔM" in runouts. Not to be confused with mastering engineer Alan Moy who worked in the same era and used a signature that may closely resemble "ΔM" but did not contain "F/W". If "F/W" is not present it may still be Dave Moyssiadis so please research carefully or ask in the forum when in doubt.
