Hevac1,
Just so you know, Audiogon members like to have a little fun now and then. The posts to your topic are not meant to be disrespectful. My own personal system thread has many jokes and jabs, including those I've put there myself.
What's distressing is the opposite reaction. Put in the work to post a new topic and NO ONE responds. At least you got answers, serious responses and some fun comments that everyone shared.
For what it's worth, my reply was serious. I do play all the music I listed as well as others I've probably forgotten.
I love rock and roll, I grew up listening to it on the radio and have tons of it in my collection today. As I got older I discovered other worlds of music that were worthwhile and as I learned about each new exciting type of music it opened me up to reach for another to add to my collection.
If a stereo has very low distortion, enough power to avoid clipping at all your listening levels and is reasonably flat (or runs toward the warm side), lots of types music works, or is at least pleasant.
That's what I strive for with my own system and although it's impossible to get every album tonally perfect, it's a goal worthy of pursuit.
The more kinds of music that sounds good on your system, the more likely you are to included it in your collection, adding to your enjoyment and choices.
