Oh come on Charlie, who are you trying to kid?
Any piece of audio gear that you would be happy with for the rest of your life?????
You're talking to your audio buds here not you wife.
The only way you would be happy with a speaker for the rest of your life is if you got hit by a bus 20 minutes after they were delivered.
The day you stop fiddling with audio hardware will be the day they throw the dirt on you..... and I don't think that makes you any different than any of the other AN members.
My wife tells me that she has visions of me reaching out of the casket at my wake, grabbing her arm and saying "Please, just one more record before they close the lid."
