How many hours weekly do you listen to your system

Definitely not enough...

Being retired I get to listen daily.The children are all grown and out of the house.The serious listening is on the 3 days a week my wife works.
On these days it's just me and my music.

Maybe 8-10 hours a week. I listen to classical FM in the mornings monday through friday for about an hour or so each day. And another 4 or 5 hours mostly on weekends. I'm getting back into enjoying more listening since I've recently bought some JM Lab speakers with a fabulous midrange. A newer CD/SACD player is on the horizon too!

Goldeneraguy ... I like your response ... it reminds me a bit of my own situation and how I work it

Typically 1.5 hours a weeknight. And up to three hours on Saturday and Sunday. So about 10 to 15 hours a week. This will increase a little if I ever retire...
