Most expencive stereo ever

Just curious, has anyone ever sought out all the most expencive gear on the planet and gotten a price tag on what a system would cost?

Lets say it has to do 7.1 HT duty as well as 2 channel and vinyl, just to keep the total price astronomically high. I think it would be kinda fun to see what kind of price tag can be possible for a stereo system.

Im pretty sure the amps would be the Wavac Monoblocks for $350,000 a pair.

I know speakers can get up to a couple hundred thousand a pair, but im not sure which brands hold the Uber-high price gear. Ive seen cables for 10k, turntables for close to 100k.

So, what are the most expencive of the Uber-priced?

I dont think there are any amps more than 350k, so how about CD transport, DVD transport, DACS, PRE, Cabling, Projector, Screen, Turntable, Stands, tweaks, etc etc?

List the most expencive gear you have ever heard of that is still in production or avaiable to be produced.

So far we have the amplification,
Wavac Monoblocks, 350,000 a pair,

Total Amplification = $1,225,000.00 (+ $80k sales tax)

Lets see how insane this can get!!!!!!!!!!!!!!!
