What's happened to the used high end market recently?? Sales are tough....:0(

Given inflated high end prices, the collapse in secondary sales prices may reflect what this stuff is really worth

Maybe, except what you stated doesn't account for the 'collapse'.

Don't get me started on MQA enabled mobile phones which Bluetooth to Hi Def earphones. There are more than enough millionares/billionaires/moguls/movie/TV stars in this world to make all Hi End manufacturers millionares themselves. Some of us aren't that privileged!

let's face it, with time the great sounding old designs become progressively more obsolescent, and to keep paying higher and higher prices for them becomes foolish.  they must have a distinct investor grade quality to keep climbing in value, i.e. they must retain or gain in value, to be worth buying.  when the prices start to drop, that's the signal it's not an investment, rather it's just a trend that has been played out, or it's been surpassed by newer developments in technology and sound.  I'm seeing this same phenom in everything vintage or antique.  what drives the prices up to the sky is big money getting interested in buying it, and when that wanes, the prices can only go down.  all these cheap knock-off Chinese-made tube amps don't help any. hopefully we can get nasty tariffs on them all, and then you'll see vintage tube gear pick up again.
