Is it worth upgrading my current turntable setup?

A more solid plinth and platter will yield more solid bass and all fundamentals of any frequency will be more firmly begun, then overtones, time decay all synergistically work together in an improved way.

my friends LT-22 has been here competing with my 3 arm setup for over a week. I put my nearly new AT440ML cartridge on it with Microline Stylus. Sounds terrific.

It’s one of the easiest TT you could own, and use.

Adjusting the arm, mounting the cartridge is pretty easy, I could help you thru it.

No anti-skate needed. No two null points to align with.

Easy arm height adjustment

Easy balance, accurate tracking weight scale.

On, start, walk away, plays, returns, stops spinning.

Up, move arm manually, play any specific track with hands free scratch free no needle drop damage assurance.

Here’s a very nice LT-20

That cartridge will sound better on this TT IMO.

As @pindac says:

Make a few contacts to see if visits can be arranged to those in possession of devices you have shortlisted and make inroads to see if you able to be offered demonstrations of items.

Take along your newly cleaned LP’s and if there is something new to pick up on and a good impression is being made, usually the improvement on offer will be noticed instantaneously.

The ears are the very best tool for such investigations.

This method of gathering experiences does not require too much of an outlay either.

If it is good now, then you really don’t want to be risking wasting funds on something that is the same, or lower, performance.

I also run a 2M Black, and a couple years ago went from an old Technics 1200 to a JVC Victor TT-81 with a JVC Victor UA-7082 in the big JVC plinth. While the turntable and arm made a noticeable improvement, upgrading my phono preamp to an E.A.T. E-Glo Petit made an even bigger difference. I haven't heard your Tokyo Sound, but I'm guessing you could do considerably better.

I’d grab either the music hall mmf-5.3 or 7.3...they both can be had with a 2m Bronze already mounted. Then, take off the stylus from the black and put it on the Bronze, both cartridges are compatible. Then, put your 2m black in a drawer as an extra...both music halls will sound better than the Pioneer.
