Most expensive Audio disapoinment?


Over the past decade, many different types of technology have come and gone.Some of the components made though quite expensive,they never lived up to consumer satisfaction.I guess I am wondering how many people jump to buy the first of all new technology only to later realize the price always drops after while.Example Pioneer AX10 $5or $7k new, now they are out dated,Door stops.

My most expensive audio disappointment is more than likely someone else's pride and joy. I don't think I'll go there.
I agree with Vegasears that this could become a sensitive thread..so the following is purely personal:
A few years ago at the FSI Montreal there was a 5.1 Linn set up consisting of probably $50,000 of gear to play Dark Side of the Moon SACD 5.1.....bad is an understatement...was it Linn, was it DSOM in 5.1 that lost me based on my 2ch reference, dunno but I came out immensely disappointed.
Krell KSA 250 - arguably one of their classic amps.
Power, bass and nothing else.
Karaoke--When is it ever going to die......?!!!!!!

Oh, never bought one...I just laughed when I saw it.
My friend's Marten Coltrane Prime, 70k price tag, Maybe the system is not right, not the speaker itself? But my friend does not want to hear it anymore after he listened Tidal Sunray.
