Hi Karl...I can't believe it will get better...

@james1969 What tonearm are you using for your RSP? 

I'm using the tonearm that came with my Technics SL1210MG5 with a KAB fluid damper attached.  I've loaded the tonearm with mass so that I've achieved a resonant frequency of 11Hz which helped quite a bit with tracking and better bass.  Tracking force is set to 1.92 grams.

Do you know what resonant frequency you have achieved with your RSP?  I'm curious if I should go lower to the optimal 10Hz?

Hard to answer that if it is sounding so good!  I use a Fidelity Research FR-64S which has an effective mass of 35 grams.  I am currently using a Jelco-Rosewood headshell at 16.7 grams.  I would assume that the resonance Hz is below ideal, but this combo won't even fit on the vinyl engine calculator. Might have to try a lighter headshell for fun.

I'm using the HiFi News Analogue Test LP to measure resonant frequency: side 2, track 2.  If you are curious to see how your setup measures.  It's an audible/visual test.

I have an Audio-technica AT-LH 18, 18 gram head shell coming in soon, I will use that, and recalibrate to see if I can make the optimal 9Hz - 10Hz frequency.
