Hard to say since I have no experience with the LP Gear Vivid Line stylus you're using, and it's been decades since I've heard an XSV-3000. For that matter, it's been about 30 years since Stanton/Pickering stopped producing Stereohedron styli (if memory serves, it was in 1993 that I bought a 681EEE Mk III because styli for my 981 LZS had been discontinued), and I would not care to trust that even if old stock styli could be found that their rubber suspensions would still be at factory spec. As a guess I'd say your Pickering/Vivid Line might be comparable to an Ortofon OM body with the Stylus 20 (which, by the way, is an excellent performer).
I do appreciate your bringing back pleasant memories. Some of the best sound I've heard was with a reasonably modest system of TD147 turntable, XSV-3000 cartridge, NAD 3020 integrated amp, and Klipsch Heresy speakers (properly located on the floor in the corners of the long wall of the room and toed in 45 degrees). This was owned by a friend, now deceased, and in the fairly large front room of an apartment he lived in prior to his marriage (he never did have as optimum a room set-up in the house they bought). Just amazingly dynamic, spacious, well-focused sound. Maynard Ferguson sounded better in his apartment than at the live shows we attended.
