Amplifiers:A Keeper for Life. Do you know of one ?

Just wondering, with this audio merry-go-round of buying and selling, if anyone has an amp that will be a keeper for life. I haven't yet but came verrrry close once...
I've got 20+ amplifiers and there's only one that i wouldn't want to part with, even if i just kept it as a spare. Since i own it though, i don't want to taint the results of this poll, so i won't post what make / model it is : ) Sean
I thought my Jadis JA80s would be the ones, but since I just sold them I didn't keep them for life, so they're disqualified. Perhaps my current Lamm ML-1s, though I still lust for the Siltech monos I heard earlier this year. Now they would be the ones I'd keep for life (or at least the life of the transmitter tube in them).
Russ, I guess I forgot to tell you when we got together last week that those JA80s were supposed to be kept until I was of the age where I could afford them...
Yeah, I know, sorry about that, Joe, I should have waited for you, but with all the remodeling jobs I've done and am doing to my house I needed the money, and my wife felt that the art deco look of those amps was nice but not suitable on her living room floor. Hey, I saw in another post that your Orchestra Reference's tubes were 6 years old, maybe you'd like one of my EI KT90 mk III quads, a lot cheaper than those 80's and certain to breathe new life into that amp!!
