With any passive speaker, I'd agree with you 100%.
Plus, I've never had an amplifier, in either my 1979 Yamaha integrated amp, nor my 2009 Yamaha receiver, go bad.
But, now, my "powered" sub (which I bought new in 2009) had its amp burn out after two years, I was not happy about that.
But, that's just one data point.
I'm not much help, am I?
I still buy used things, in fact I just bought a used, rather expensive, camera lens a couple nights ago, haven't received it yet. I
don't buy "factory-refurbished" anything anymore; I bought 3 items in that category over the years, and all three were not worth the headache. Again, not statistically meaningful, but when its your own money involved, them data points become more "weighted".
FWIW.
