Woofers getting workout, but no bass

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

Is that not a subsonic filter?

"Is that not a subsonic filter?"

Technically, perhaps not, but essentially the same effect most likely from a practical perspective, and perhaps not switchable in/out. Probably a good thing still.
