I recently purchased a Denon DL301-II cartridge for my DP-47F turntable and before I install the cartridge I did some research using the tools here on the site. Using the alignment calculator it appears the Baerwald alignment will offer somewhat better max and avg rms distortion values than the Stevenson alignment.
Being on the learning curve, I've reached a conclusion or two about the Baerwald and Stevenson alignments and would appreciate your critique of those conclusions.
The Denon DP-47F has a pivot to spindle length of 204, overhang of 16 and an effective length of 220. These values are very close to the values in the Stevenson alignment at 204, 16.679 and 220.679 respectively. I conclude then that Denon uses the Stevenson alignment for the DP-47F.
The Baerwald alignment specifies pivot to spindle length as 204, overhang of 18.698 and effective length of 222.698. I conclude then that the overhand will exceed the factory recommendation by 2 millimeters. The ability to achieve this overhang will depend on the length of the slots in the shell.
The Stevenson alignment calls for an offset angle of 23.826 degrees. Though the Denon literature lacks this specification, I "assume" the shell has an offset angle of 23 degrees based on my earlier conclusion that Denon uses the Stevenson alignment.
The Baerwald alignment calls for an offset angle of 25.135 degrees, 2 degrees more than the assumed 23 degree angle of the shell. This means the cartridge will not be parallel to the shell as detailed in the Denon literature. Again, the length of the slots in the shell will determine whether or not the Baerwald alignment can be achieved.
So, are my conclusions correct, or am I off in the weeds somewhere?
One final question while on this subject, considering the equipment stated above, will the differences in max and avg rms distortion between the Stevenson and Baerwald alignments be discernable?
Your comments are greatly appreciated.
