Slappy, the question was regarding the $1,000,000 to spend on audio, not that you had only a mere $1,000,000!
I would build an amazing room in which to keep the system. Then I would buy a pair of Kharma Exquisites (I think is the name, there's $130,000 down the tubes). I would have Stan Klyne build me a cost no object pre-amp (there goes another couple of hundred dollars) I would get the Halcro monoblocks. A Sota Millenium TT with an SME 5 arm and a SHelter 901 cartridge. I would have modwright upgrade my Sony SCD-777es with all the whistles and bells (digital really isn't that important to me). All my cable would be Purist Dominus, unless they make a better cable before this windfall.
Then I would have an opening night concert for my friends and have a few of my favorite bands play my favorite song.
