Guess I'm a man of slightly simpler tastes than some. Ignoring the room (cause if you have money the room is a given and rather uninteresting), my system would be:
1.0 CD Transport - OPPO BD 105
2.0 Ripping software - dbPowerAmp
3.0 Computer - Intel NUC 9 (or latest version depending on date)
4.0 Router - Asus Rapture (latest version)
4.0 Storage - Qnap TS Series NAS with Intel Optane SSDs
5.0 Cables - Mogani gold
6.0 DAC/Preamp - Benchmark DAC 3 HGC
7.0 Amps - Benchmark AHB2's
8.0 Speakers - KEF Blades
9.0 Sources - Ripped CD's (but have someone else to do it for you and add in all applicable metadata). Spotify for identify what to buy / rip.
10.0 Player Software - Foobar (cause it is just cool)
11.0 Headphones - STAX SR-009S
12.0 IEM's - Stereo Pravda SB-7
Cable lifters and "All that Jazz" - none
Only audio component I have not seen/heard in this MtDream system are the KEF Blades. Selected these on discussions (late nights involving Bourbon) with a friend of a friend (whos' opinion I highly respect and has auditioned alot of "high end" equiptment), as they are the only speakers he has ever raved about.
