Well, leased receivers are replaced at no cost (if you have protection plan) or for cost of shipping (about $20) if you don't. Cost to replace owned is whatever you have to pay to buy (or lease) another receiver. So with leased, you won't get obsoleted. However, to each their own, and there are some arguments for owning (which is becoming hard to do).
As to vinyl LPs, they do sound good to me (as long as you are careful and don't get them scratched).
Not true receivers are replaced whether leased or owned ....if one has the protection plan then owned receivers are replced as owned...otherwise any receiver will be replaced for S/H $19.95
