Audioguy85, buy a Hi Fi news test record and run the resonance test tracks. You will find the warble starting above 12 Hz. You have to stop making assumptions and learn to measure the performance of your system on your own. The OP complains of lack luster bass. No review that I have read says this of the Hana. The Hana being a typical Japanese MC cartridge was designed for their favorite heavy tonearms. The OPs arm will run best with cartridges in and around 15 X 10 (-6) cm/dyne like Ortofons and Lyras. Jeff, the screws are not expensive. If you get them please tell us what you discover in using them. It would help this discussion in a major way. This is where the truth is :)
Paulgardner, yes, you might benefit from some additional weight. You can get the afore mentioned Soundsmith screws an play around empirically or spend a little more and get a test record to get an idea where you are. I prefer having a test record. I don't like guessing. I have subwoofers that run perfectly flat down to 18 Hz and have found with a number of cartridges that running your tonearm resonance frequency down at 8 Hz produces the best bass performance, as good as high resolution digital.
It is important to remember that between 8 and 16 Hz is an entire octave!
