The most dramatic sound differences typically come from a stylus or cartridge upgrade, but there are some tweaks you can do to help optimize what’s there.
- Build or buy an isolation platform....Google some ideas
- Add a few orthodontia rubber bands or orings along the tonearm.
- coat the underside of the platter with Flexseal or rubber undercoating
- setup and alignment are always critical...for both the TT and the whole system
- Add a record weight to increase mass (helps reduce resonance)
- Add some weighted grip tape around the counterweight to move it closer to the pivot point...you’ll need to rebalance the arm and tracking force (shortens the moment of inertia and requires less energy to move the arm, essentially making it more nimble)
No guarantees any of this will lead to audible improvements, but are a step in the right direction and shouldn’t hurt anything. The rest of your system will be a factor in how much you can hear.
