Sure, a great producer with some cool and timely ideas, but I wouldn't position him above a lot of other greats like George Martin or Jerry Wexler or Quincy Jones. I think Jimmy Page has more going on, and better ears, or least did. Peter Asher is another.

As for his sins, Spector was an utter asshole who, I suspect, never had to come to terms with his evil because he was alright with it.
