By far the most incredibly stunning performance on SDAs I've heard so far is,
QUEEN; "A Night at the Opera" All of Side 2, yes this is the side with Bohemian Rhapsody, 21 foot soundstage, 6 to 8 feet deep. Absolutely incredible. I played the MFSL LP. It was like I heard it for the first time.
I first listened to Abbey Road, then Eldorado (ELO) and was really on a roll then this just blew me right into SDA Heaven. The a cappella of the first track was so realistic.
This was an eyes closed, all night, speaker disappearing act.
