I'm located in WA state. I listen to more types of music now but opera I just can't listen to. Classical is fine but not knowing much about it, it's hard to know what was a good recording. I mostly listen to rock and have a bad habit of playing it loud from time to time. Problem is some rock is so poorly recorded it doesn't sound good no matter what you do. I listened to the quatros at Advanced Audio in Tacoma WA. We even played some vinyl and it made me want to get into vinyl again... just more $$$$.. It's just that when we played Pink Floyd Dark Side Of The Moon (on vinyl) it didn't have the punch and authority like when I heard it turned up on some Martin Logan Summits. The Summits actually impressed me allot. They have 2 10" powered subs built in also. They are more efficient than the Vandie's, you should give them a listen. For the type of music your dad enjoys, I would say he made a very good choice in speakers.
