Congratulations @ozzy62, nice table!
I have an Aries 1, and the only difference between the 1 and 2 is in the platter and its bearing. The 1 is fitted with a 1" outer diameter, stainless steel bearing housing and threaded (for a reflex clamp) spindle. The platter is comprised of 1- a 7/8" thick bottom section of aluminum, with a sheet of cork-covered lead bonded to it’s underside; and 2- a 3/8" thick sheet of black Delrin bonded to its top, for mechanical impedance matching to the PVC of LP’s.
In the Aries 2, Harry Weisfeld switched from the aluminum/lead/Delrin "sandwich" platter to a solid frosted-acrylic platter (2" thick, I believe). He also dropped the "standard" bearing and went with an inverted bearing. VPI still uses inverted bearings in their current line-up, but Harry eventually decided the move to an acrylic platter was a mistake---a step back in terms of sound quality, and now use only metal platters (aluminum I believe, not stainless steel).
Some regular posters on the company’s forum site remain fans of the Aries 1/TNT-3 & 4 platter (all use the same aluminum/lead/Delrin platter described above), as well as the TNT-5 platter, which is a bottom section of 5/8" thick stainless steel (no lead) and a top section of 7/8" thick Delrin. But both platters use the standard 1" diameter bearing, so can’t be swapped for the inverted bearing of the Aries 2, whose housing has a larger outer diameter. But I believe a current VPI aluminum Classic platter can be used in place of the acrylic, as it too uses an inverted bearing
Then there are all the different versions of VPI motor pods, flywheels, and even a rim drive to replace the belt. As far as I know the Aries 1 & 2 had the same motor/pod, the motor itself the same Hurst used in the HW-19 table, and even the various iterations of the TNT.
As for the basic thrust of your post, that I can’t comment on. I’ve heard older tables like the Oracle Delphi in the same system as a TNT (it and the Aries are more alike than different), but that was a long time ago. There are now a lot of mid-priced tables available, all with their own sound it is said. You’re probably going to be hearing from owners of them ;-) .
