I wonder what theory stood behind Denon VL12 tonearm geometry design in order to obtain optimal two null points cartridge (stylus and cantilever) alignment? If we are to follow the published specifications the result is more than disappointing, leading to tracking errors of about 11 degrees, which may be a serious design flaw.
The only way of achieving optimal two null points alignment seems to be as follows:
- increasing the offset angle by twisting the cartridge about 4.5 degrees, which is quite a lot, in order to obtain an offset angle of 25 degrees.
- adjust the overhang to about 20 mm in order to shorten the tonearm effective length
The assumptions made in here are as follows:
- effective length: 238.76 mm (according to the official published specifications)
- overhang: 25.4 mm (according to the official published specifications)
- mounting point (spindle to pivot point length): 213.36 mm (deduced value by subtracting the overhang from the effective length)
- tonearm offset angle: 20.5 degrees
If the official published specifications are wrong and someone has the correct specifications, please, feel free to post them.
