This is incorrect. Just the opposite is true since most tonearms are designed with stable balance, which means that the arm CG lies below the vertical pivot point. This causes increased VTF as the stylus height increases. After reading this thread it sounds like the 4Point arm is designed with...
Interesting review from Jeff Day on new Acoustic Revive Headshell

Compared my Valhalla 2 and a friend’s Synergistic (forgot the model). Both of those sounded unnaturally bright in comparison, surprisingly. The Arhat exhibited a relaxed presentation with an enveloping soundstage and without masking detail or blunting transients. It just seemed to make acoustic...
Yes. Here is an example: this Jazz Messengers modern mono reissue exhibits severe distortion on plucked bass notes when played with my Miyajima mono cart, but plays perfectly fine with my stereo cart. This implies the presence of spurious vertical information due to the stereo cutter head used...
Much earlier. Professor Erik Löfgren of the Royal Institute of Technology in Stockholm, Sweden, developed and published the first tonearm alignment equations in 1938. Baerwald, Bauer, Stevenson and several others who came after Löfgren produced identical equations differing only in notation and...
L? = (L?² + D² ? 2L?D cos?)½ , Arm effective length with A-style SPU
? = arcsin (L? sin? /L?) , Arm offset angle with A-style SPU
L? = Arm effective length with G-style SPU
D = 21.5 mm difference between SPU-G and SPU-A mounting collar to stylus distance
? = arm offset angle with G-style SPU...
The RMG-309 null points are 60.0/115.4. If you want to maintain these same null points then with the SPU-A, you should set your pivot-to-spindle distance at 287.6 mm. This gives an overhang of 11.8 mm.
This is the identical one I used to have long ago. To be precise, as shown on this spec sheet, it was a SD 900/E+ Super. After this cart I had another Supex - the SDX 1000. Not sure if it was also a Sugano design. It had a boron cantilever. The body was rounder and more petite. Anyone remember it?
If your platter has a recess for the record label then any weight much over a pound will lift the edge of the record noticeably. In which case you could benefit from an edge clamp.
The Telarc, despite its Soundstream origins, has arguably the best sound of any version on vinyl, along with a top class performance. The reissue by Craft Recordings is excellent though the original issue might be preferred by some. They’re very close.
These are great comments. Thank you. I especially found fascinating your experience with a power cord plugged into an outlet but unplugged at the IEC end. That situation exists currently in my system and I will do some experiments.
Also I just ordered a Hammond 171A isolation transformer to try...
Interesting thesis. This suggests that perhaps running the motor controller off of an isolation transformer could be useful to keep the nasties from infecting the rest of the system. And I have also observed that the effect is of the same magnitude as on a preamp.
