Congratulations. I remember when I upgraded from a “common table… the reissued AR) to a VPI Aries… it was one of those jaw dropping moments I have never forgot. A completely different world.
If the system was mine I would upgrade the cartridge… get a good one… think ~$2K or more… I don’t know your tastes or am I familiar enough with the current round up of cartridges… I have a Koetsu Rosewood Signature… a beautiful natural sounding cartridge. You need one for your tastes and system. Then the phono stage for sure. I am a big Audio Research proponent… 30 years ago after purchasing my first a PH2… that was it. I own there flagship now after many upgrades. Phono stages are way more important than you think… a really high end tube phono stage improves naturalness of the sound, detail an quieter the background even more. If you don’t get it right at the cartridge and first level amplification… it doesn’t improve more.
