Great replies thus far! Most get the drift....an accumulation of stuff not being used, for say, in a second or third system some place else in the house. Just stuff for whatever reason you cannot part with....
For instance, I have 5 turntables, all worth about the same, yet I can only listen to one...I realize I could sell all 5 and spend the money on one that may be substantially better, however I cannot bring myself to part with them...maybe I like the variety of having different types and/or flavors...
"So, having a bunch of stuff around is just having lots of stuff with different weaknesses."
Great point, and something I have not given much thought about....
