At what vol level do you get rumble / flutter?


Hi everyone. I hope my Pro-ject Xpression has not started the dreaded rumble / wow / flutter problem. I recently tried a heavier MC Ortofon on my table and after switching it in and out (professionally done), my table will make the woofers rumble / wow / flutter as soon as my normal cartridge (Ortofon MC-3 turbo, HO MC) hits the record with the volume at about twice as high as my normal listening position, which is not party cranking levels, but twice as high is and that is where I see the rumble. Would you say this is normal for Pro-ject and similar tables? Will a Rega RP3 act similarly? Rest of system is posted and it is less noticeable with the rumble filter on. From what I remember, my table did not do this before the cartridge swap. Luckily, it is still under warranty.

TIA

There is rumble recorded in about 50%+ of the records I own, and it has NOTHING to do with set-up or placement or arm/cart matching. When I go to the audio shows I always notice woofer pumping, even on super $$$ set-ups. On a lot of LP's it is unavoidable. KAB's rumble filter is a God-Send and seemingly transparent, at least in my system. When I play LP's, I flip on the KAB.
