Woofers getting workout, but no bass

Well so far I've reversed phase, add damping fluid to my Triplanar arm, double checked level, tried raising lowering VTA, all to no avail.

Kevin at KAB suggested that his filter would be a bandaid and that damping should be the real solution, but unfortunately that didn't work.

Apart from trying a filter, I'm left with the notion of replacing the table, arm and/or cartridge, all very painful thoughts. :-(

Madfloyd, I dont think those choices will solve the problem. It's a phenomenon we all deal with when it comes to vinyl. Oh, I think the title of your thread is hilarious btw. lol

Agree with Vandermeulen and others. Don't change your table, tonearm or cartridge. There's almost no chance that would reduce woofer pumping.

I find Kevin's suggestion regarding damping fluid rather odd. Perhaps it would help on one of his tonearms, I don't know them, but it wouldn't on a TriPlanar, at least IME.

Did you experience less woofer pumping when you had the Doshi preamp in your system (if you remember)? Compared to our c-j, the Alaap reduced WP a lot. Nick doesn't include a rumble filter per se, but his circuit is designed to roll off around 16 Hz or so IIRC, which helps.

Thanks, Doug. I did remove the damping fluid as I didn't like what it did to the sound (I've now removed the damping trough as well).

I wish I knew whether the Doshi worked better in this regard, but it was only recently that I removed the lower grills; I have no idea how long this has been going on.

I did try an old Project Tube Box SE II phono stage that I still have - it has a subsonic filter (18hz with 24db slope) and that worked (not that I would use it as my phono stage).

there is the answer. there are a few highend stages that have built in filters. Tom Evans comes to mind
