At What Age Does An Audiophile Buy His Last Amp?

I am 74.5 years old and I just ordered a pair of Herron Audio M1A mono
amps. I plan to enjoy them until I am at least 85.

I retired a few years ago and bought a Brystom amp with a 20 year warranty. Since my last amp served for about 17 years and was great, and the only reason I upgraded was i had a big pile of money to throw away...
I am pretty certain this Bryston 4B-SST² will be my last amp.

If I blow money on equipment, it will be on 20.7 Magnepans.

Well that's a bit revealing, Elizabeth. Why don't you already have them? I sure would and I'm only 56. As Airegin stated, hearing is probably going to be the major factor in answering this question. But I mean in terms of satisfying one's hearing deficit which will most likely include hearing aids, and/or of sorts.

so have another hit of crystal clear music. It's the trip, man, not the destination! What does bother me though is the congregation of the audiophiles getting older than an episcopalian assemblage
( judging from how many of you recognized those misquotes). We've got to get younger people involved. Start a thread about how to best do that....and don't go passive on us. We're counting on you.

Each his own, but I decided to stop now in my 40's when I listened to several $500.000,-- ++ Systems which were sonically so inferior compared to mine that it made no more sense to continue ..... my amps are matched to my speakers btw.
