Quick report for ya. Def Leppard (Greatest Hits - 1980 Vault 1995) and Journey (Greatest Hits) sound really good! Steve Perry's voice is very smooth, Neal Schon's guitar is smokin and Steve Smith's drums are solid. I was surprised at how good the Def Leppard cd sounded. I hadn't listened to it on the M60's yet. These old bands sure bring back a lot of memories. I was listening to some Motley Crue the other day and the bass and drums were unbelievable. If you can swing it, go for the M60's.
Cheers,
Shaun
