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

Curiosity empties wallets.   If you're happy, go no further  

That is true.
But also is true then that we would all be stuck with Tandy and Radioshack pieces if we did not let curiosity out of the bag now and again.....

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?
