What rock song sounds the best on your system...

Jeff Beck and The Yardbirds... with Rod the Mod... Stewart. :-)
That's the Beck I'm talking about...

if i had to choose one, it would be "Babe I’m Gonna Leave You" from Zed Zepplin 1, 15 ips, 1/4" master dub, followed right behind by "You Shook Me" and "Dazed and Confused" also on that same ’reel 1" of that same master dub.

played at warp 9 on the Studer on my big rig it takes no prisoners.

Rock n’ Roll was never the same after side 1 of that album. Rock n' Roll may not have ever been as good again as it was after side 1 of that album. and it just happens to be a great recording too.

Almost every track from side two on from the Rhino Records two volume Roy Orbison Anthology LP set.

Anything from Dire Straits!!

Rock? Pretty much anything... But going big, Sevendust kicks ass! I have to agree with MC on the Joshua Tree comment. Sounds fantastic on my system. The vinyl just kills it!
