I think I have tried about everything. The higher output cartridges definitely make it more sensitive. The only way I have ever been able to eliminate the problem is by suspending the TT from the ceiling. I have used black chains and cables. 1/16 cable looks real nice. I have it supporting a piece of 3/4 granite. My TT is a Pioneer PL7L running a Ortofon Cadenza Red. My speakers are 3 feet away from the unit and I have zero issues. I can crank it up and it hits nice and hard.
