New TT vs Cartridge/isolation upgrade

New table and cart.

The Hana EH is an elliptical stylus, Moving Coil, specs nothing special

Do yourself a favor and buy a cartridge with an advanced stylus shape: linear contact; micro linear; SAS, Gyger ... 

MM or MC with advanced stylus. Existing is MM Elliptical. New MC if prepared to get proper SUT with proper x factor and impedance.

any advanced stylus shape, MM or MC will be superior to an elliptical. They cost more, however, they have longer life, therefore overall, you get better performance for not much more at all.

This explains various stylus shapes easily

Now: better imaging: remember, center is phantom, created solely by L/R matching volumes. A cartridge with tight channel balance will do a better job of locating anything anywhere as intended.

Wide channel separation combined with tight center balance will yield better imaging than you are used to.

Here is a very good affordable MM cartridge with advanced stylus, wide separation, and tight center balance:

compare to your present 2M red specs

Wide Channel Separation, on some recordings, can be too wide.

Toe-In. I recommend the ability to adjust toe-in: for single centered listener; in a bit more for single listener IF too wide imaging, and toe-in much more for two listeners, each off-center. Toe-in whereby the left person is closer to the left speaker, but the right speaker is facing them; opposite right listener is closer to right speaker but the left speaker aimed more directly. Both listeners retain decent L/C/R imaging that way.

Just enough 'slip' material relative to speaker weight to allow movement.

As for TT, I do not like any of this level TT with a fixed headshell.

Easy for the maker to pre-align it, works out of the box for anyone with zero alignment skills or tools.

However, any worn stylus cartridge replacement; any upgrade like you are intending, any cartridge change will require basic alignment skills, several inexpensive tools.

A dealer, a friend, and I certainly recommend you eventually learn and acquire the simple tools and skills for the rest of your life.

A removable headshell gives you the freedom to have MM stereo; MC Stereo; Mono; Elliptical; Advanced Stylus, as you may 'grow into' as your vinyl interest develops. This freedom of flexibility is far more important than the 'fixed is better than removable' bs. SME's, others, world renowned, were removable headshells. They became famous with that feature.

Whoever introduced the fixed headshell might have saved themselves some money but they didn't do anyone else any favours.

Another classic case of manufacturers selling folks short whilst telling them it was for their own good.

If you must upgrade then Option 1 seems better to me.

All turntables benefit from better isolation - some of them incredibly so.

Especially when as you say, "either TT will sit on a pretty solid wooden credenza".

If that doesn't satisfy you then you'll need to save up for something substantially better.

Decks such as the Technics SL1200GR or Rega 8 will also benefit from an improved isolation platform.

The best form of turntable isolation is probably another question altogether possibly involving the use of accerometers and stethoscopes.
