If you do extend your investigation to A/B Comparisons. I f carried out at the Dealers do make sure both TT's are demo'd on identical mounting along with identical supporting Audio Devices downstream. The identical Cart' set up may be more difficult to achieve.
If a home demo' can be arranged, this will be even better for your deliberations to follow.
The more effort put into discovering methods that can be adopted to mount a TT, with the intent to decrease ambient energies being easily transferring to the Styli. Creates a TT, that can become unrecognisable to when it has been used on a Mount that has not been considered to substantially reduce / resolve the transferral of ambient energies.
