The Guthrie-mixed sacd 5.1 version of DSOTM is quite good, certainly quieter.
But Parsons' original quad mix from the '70s, (4.1 on dvd-a), is a much more exciting recording than Guthrie's "safer" mix, IMO. DSOTM is the one album that screams for the envelope to be pushed, not throttled back. As far as I'm concerned Parsons had it right.
