| Woofer pumping possibly due to tube amp when playing vinyl Larry,I know it’s the TT per se, but it seems like some sort of interference is ramping up the pumping, because it doesn’t pump in the other room in the same set up - TT, cart, rack.to you comments:1. I have bought the ring. Hasn’t arrived yet2. I... | |
| Woofer pumping possibly due to tube amp when playing vinyl Sorry guys. It’s NOT THE TT’s. All three do it on all different rack types. There is no way you get the exact same results on three different TT’s, sorry, that’s not the case here. Is not induced by the music. It happens on quiet passages. No mus... | |
| Woofer pumping possibly due to tube amp when playing vinyl Muteur, It’s not about better equipment. My equipment is just fine and many people have the Same gear without any issues. | |
| Woofer pumping possibly due to tube amp when playing vinyl Big gregthats not the system that pumps, that one is the one in the “other room”. I don’t have pics in the Woofer pumping room. | |
| Woofer pumping possibly due to tube amp when playing vinyl Psag,Thanks. But compatibility isn’t the issue. The same equipment and rack in another room doesn’t cause pumping. | |
| Woofer pumping possibly due to tube amp when playing vinyl definitely don’t agree with the “need a better table than the ones listed” comment. All 3 of these tables have been in another system with No issues. Today I brought my other system in the same room as the offending system. Mind you the other sys... | |
| Woofer pumping possibly due to tube amp when playing vinyl Yes the KAB is an option, but I want it to be my very last, but only after every other variable has been looked at. While I know some say it’s transparent, others have said otherwise.To be clear the rack has not been constant. Anything but. The TT... | |
| Woofer pumping possibly due to tube amp when playing vinyl And now I tried it with a third TT and cart. A Technics 1200 GR with an AT33sa (MC cart) and the pumping still goes on. And this time the TT was carpet, so no way vibration traveling through the walls or floor. Also, this same turntable and phono ... | |

| Woofer pumping possibly due to tube amp when playing vinyl I can also tell you the clamp isn’t the solution. I’ve got the VPI clamp that is dished on the underside and comes with a washer, but unless your clamp goes all the way to the edge of the lead in grooves, It ain’t gonna flatten those slight rises ... | |
| Woofer pumping possibly due to tube amp when playing vinyl Thanks for your input guys. I just tried the mono switch on the preamp and it did somewhat reduce the pumping. About 30% less excursion as a best guess. I did relocate to a concrete floor to a completely different part of the room no avail. | |
| Woofer pumping possibly due to tube amp when playing vinyl All my carts I have tried fall within the correct EM range. Some of the carts are suggested by VPI themselves. | |
| Woofer pumping possibly due to tube amp when playing vinyl Thanks for the responsesto answer some questions:no sub is in usemy preamp does have mono but didn’t affect the pumpingI will try different speakers to see how that goes. | |
| Woofer pumping possibly due to tube amp when playing vinyl Larryrs,I have considered this but the nearest appliance is a gas range opposite Side of the wall. If there is a phone app I’ll certainly give it a try. Got nothing to lose. One thing I don’t understand is the speakers go down to 32hz, but sub-Son... | |
| Woofer pumping possibly due to tube amp when playing vinyl Dekay- I did hook up another amp, my CJ MF2100, still the woofers pumped. |
