Vintage Turntables compared to modern?

I have ditched modern decks for vintage but with modern arms. I am using a totally hot-rodded Thorens TD124 mated with a 12" Reed 3P and I have a mint grease-bering ivory Garrard 301 being worked on with a 10.5 Reed 3P. The Thorens has a much more robust main bearing that was custom designed by Greg Metz of STS/Classic Thorens and implements a ball on ball design and as you can see, a heavy cast aluminum top-platter. On the Garrard I am also replacing the main bearing with a more robust one made of brass from Peak HiFi in England and also from England is a matching PSU from Classic HiFi in England that will reduce motor vibration as well as controlling speed.

I sold my VPI Avenger after getting an Artisan Fidelity 301 Classic. I have been working on it over the past couple years upgrading it piece by piece. The table is a couple pieces away from the Statement Level.  After getting to the Statement level I would like to try the Acoustical Systems Special Decouple Platter (SDP).  My goal is to maintain the drive of the idler and get near belt like quietness. At this point the table is more of an ultimate performance quest than a value proposition. Its fun too with a sense pride in ownership.

I don’t care about modern turntables at all, 99% of them are so ugly that i don’t want to use them even for free, also i would like to avoid belt drive and idler drive as well. The prices for modern turntables are insane, except for the new Technics. All i need is direct drive like Luxman PD-444 and Victor TT-101. There are many more things to improve, but those turntables are so good that i don’t even what to think about replacement.

Yesterday i’ve watched this video from Capital Audiofest and recognized that people at Zu Audio also uses Luxman PD-444 with low power First Watt SIT amps and their super high sensitive Druid mk6 speakers with full range drivers. I believe these guys could use any modern turntable, but they are uzing the Luxman PD-444.

I have no idea why do we need those $30k modern belt drive turntables if we have DD like Luxman for under $3k designed for two tonearms?

I'd like to get a hold of a minty older Sony (PS-X800-700-555ES) or some other vintage auto table.
