I have an original Aries Extended which uses the 12" arm vs. the 10" arm of the standard Aries, which I assume is what you have. I've changed a lot on it; aluminum platter (used) and periphery ring (came with table along with frosted acrylic platter), Unipivot Needle Assembly (new), an early 12.7 tonearm base assembly (demo from VPI), and IsoAcoustics Gaia II feet (new). I still have the original JMW-12.5 arm and motor assembly. I also have the single motor flywheel (used) but not using presently, mainly because I don't have (or really want) a 30" wide platform on top of my rack (I can't use a low table, I have cats ...).
I agree with most of what the others have said, you have a very nice table and it can be a very expensive journey, but from a cost standpoint there are a few things you can do relatively "cheap". First, if you haven't already, replace the Unipivot Needle Assembly ($115 from VPI; note: it's not really a knife edge, it's a very sharp very pointy and very hard needle). The needle point is likely dull if it is the original. A new one will have less resistance to movement and resultant better detail to the music.
A second, more costly upgrade, would be a used replacement arm, either a stainless steel version (pretty rare) or a 3-D printed version (more common, but stay away from the early ones with the finger lift built in, the finger lift breaks). My only hesitation on the arm is VPI moved from a 10" to a 10.5" arm along the way and getting the 10.5" to work on a standard Aries may require moving the arm base. Slight aside, the VPI forum used to have a LOT of information on this (and a lot more) but a lot of that data was lost a few years back. Matt is trying to recover as much as he can but it's not going well.
A third improvement, as mentioned by others are the feet. As I mentioned I use the Gaia II; for a standard Aries, which is lighter than my Extended, the Gaia III ($200, work with up to 70 lb. total for the four feet) would likely be a better, and cheaper fit. There are a couple of offerings from VPI, but they are pricey. I think the HW-40 feet are the best and most likely to provide a noticeable improvement, but they're $475. I tried the mini-TNT feet and they were ok, but they're in storage now ...
One last thing, if you have the original platter, i.e., the composite one made of aluminum and black composite (can't think of the actual material) stick with it, that's a very good platter. The only downside is it can't accommodate the peripheral ring, which I really like, but others not so much.
You can be very happy with what you have, the cartridge is very important and you have that part of the battle covered. Piecemeal upgrades can help but they can be a rabbit hole (I know from experience). Good luck with your (continuing) journey!
