We're still using the same methodology we have described in the post about the typical tonearm resonance measurements
. The accelerometer is attached to the top front of the headshell, and the vertically modulated 0 to 20 kHz sweep recording is played. The output from the accelerometer is conditioned, amplified and converted to g
. We're keeping our tradition of using the Audio Technica AT7V
cartridge for the vibration measurements.
Here's the comparison of the Korf CB-A01 spacer, the Audio Technica AT633, and the Rega RB300 without any spacers at all. The Korf spacer is made of the same material as the AT, has the same geometry and mass, so it should perform the same. Right?
