Do you ever just listen to music

The only moment when i do critical listening to a system is when buying. Other than that, i enjoy the music.

Nope. Unless i'm listening to my Sennheiser 650s

Mrtennis....I agree with much of what you say, but where does the math come in with the exception of Bach?

I've noticed I am overly critical of my main system and tend to enjoy it less(even though it's much better) than my secondary system of which not much is expected, just music

strong correlation between musical talent and math aptitude

Correlation is a dangerous word, since it might suggest that one thing is causing another. For instance: There is a strong correlation between tattoos and motorcycle accidents (tattoos are causing motorcycle accidents)

Washington DC has three times more police and eight time more murders than Denver (same population). More policemen = more murders (strong correlation).
