Buy a $40,000 10 year old amp for $4,000 or new amp for same money?


Hi. There are bargains to be had on really high-end components that are more than a few years old. DACs change too much and we need the newer technology. How about amps and pre-amps? I know it can depend on the specific amp but in general is a 10 year old amp that was $40,000 in 2009 and now sell for $4,000 a better value than a new amp that sells for $4,000 in 2019?  How much has amplification evolved in the past decade or so? (I posted a similar questions about speakers in that forum). Thanks for all the input and wisdom.

@mcmanus has posted the same questions about DACs, Speakers and Amps.  Silly questions!
Hi,
from 40k to 4k in 10 years time something is not right.
Well, think of Wilson Speakers...

I think there was a pair of wamms for sale for close to 75% off their original pricebut the wamms are probably far inferior to the alexandria xlf'sive also seen some older wilsons sell for about 50% off, but i think the new ones like daw, alexia 2 will retain value a bit better. at least until the daw 2 or alexia 3 comes out.
