OK, I’ll play. I love spending other people’s money!
I’ll assume your listening room is already sorted out.
You haven’t mentioned any sources - streaming, vinyl, CD/SACD, so I’ve chosen to focus on CD/SACD. You’ll notice that I’ve stuck with one company (except for the digital source). I’m a big believer in component compatibility (i.e. components that have been ‘voiced’, or designed, to work with one another). Plus, you have much more room to negotiate (price) when buying a complete system from a single company.
So, here’s my list:
Speakers: Coincident Reference Extreme II new - $30,000, used - virtually unobtanium
Amplifier: Coincident 211PP Dragon MK. II new - $11,000, used ~$6,000
Linestage: Coincident 300B Statement new - $7,000, used - $5,000
Digital Source: Esoteric UX-1 (Modified by APL HiFi NWO) used only - $7,000
IC cables: Teo Audio GC Ultra Balanced (2 pairs) new - $5,000
So, total budget comes in around $60,000 (buying mostly new). I haven’t recommended speaker wire or power cabling but you have enough left over in your budget for your favourite flavours (e.g. Shunyata, Nordost, Cardas, Duelund, etc.).
Good luck in your search!
