For that budget I would investigate
Brinkmann Balance 2 arm with Ront Tube power supply
Techdas Air Force 3 Premium
both of these would be around the $40k mark before negotiation.
For the Acoustic Signature you would have to go to the Ascona Neo @$50k retail to meet the performance of the Brinkmann/Techdas.
As an aside - if you want to explore vintage a mint Micro Seiki 8000 mk1 can be had for around US$25k, which according to some owners of both is as good as the Air Force One ( north of $100k ). It may require a little extra effort for any parts, maintenance etc but the performance is at Airforce 1 level.
