I love DSOTM and The Wall on my system - Bryston B60, Rega Apollo, and Audio Physic Yara Evolution Bookshelves. I also have them on vinyl, and my Pro-Ject 1Xpression with Speedbox II and Dynavector 10x5 presents them in an equally well, yet different way.
I've heard both albums on several systems. My favorites were ATC active floorstanders with an ATC preamp and Linn LP12 with Lyra cart, and Mac seperates with Totem Arros.
My only criticism of both albums is I think they used a bit too much echo in the vocals. Sometimes it gets a bit distracting to me.
