The urge to tinker is awash. What TT might better mine and why?

If you haven’t already, try a tubed phono.

Just MY opinion-it delivers a more convincing, realistic presentation. They may be a wee bit hissy at stadium level volume, if that’s your thing. Ever notice in some SS unit reviews, the reviewer writes- "almost tube like" or something similar?
Hmm...??

Look used/demo and get half of retail. Pass on specific suggestion. Something in the 2-5K range will get you a keeper.

Your system profile looks solid. Audio Nervosa seems to flare up among us, now and then.

When that happens, I just play a new bin find.

Perhaps I could have phrased it better
Yes I can change the tone/ sound with a different cart or phono stage but that’s not what I am asking.

What makes a better TT than I already have and why?
What features would be improved upon and how much will that cost?
Better motor?
Better platter?
I mean I know there are considerably more expensive TT out there so what/where do I need to be looking?

Try an idler drive turntable. Garrard 301/401, Lenco, etc

The sound is more dynamic

Why might an idler drive TT be superior to what I have?
I am a little surprised that nobody has come forward with their particular TT of choice and giving some good solid reasons for choice of same.

Definitely not going to splurge any moolah without some basis for what I can potentially expect.

Seems like there are mixed reviews on your table. If I was starting from scratch, I would look at a 301/401 with new massive bearing and heavy platter in the right plinth with a top notch arm. I don’t know your budget but as a starting example of cost, my rebuilt 401 with custom idler in a slate plinth and decent arm set me back less than $4k. It sounds wonderful - musical, transparent, resolving, and utterly involving. It is also a respected reference class transcription table that has stood the test of time.
