The 550 implemented Dolby-B in discrete transistors, and the 350 uses an IC. The 550 is adjustable, the 350 is not (or if it is, I don't remember). The 550 Dolby circuit sounds incredible...it sounds great. [Anyone taken it apart to find out the implementation? -tjk] -- "Worship the Lord your God, and serve him only."
