Thoughts? I was surprised to get worse sound with e Baerwald given what I've read on this forum.
No, you definitely
shouldn't get worse sound quality. I'd echo watercourse's comment about mixing and matching alignments? You don't say how you've aligned it, but a common mistake is to set the overhang using an arc protractor but leave the cartridge square in the headshell. In a Rega this will increase tracing error/distortion at the inner and outer grooves.Red: Standard alignment
Blue: Rega offset angle / Baerwald overhang
If you've aligned correctly to Baerwald null points, tracing error and distortion should be lower virtually everywhere.Orange: Standard alignment
Red: Baerwald offset angle / Baerwald overhang
PS Rega alignment in the first plot looks a bit lumpy but this is due to the scale used - as can be seen in the second plot, it's actually very close to Stevenson.
PPS This is all based on the inner recorded groove having a radius no smaller than 60.325mm, which is the IEC standard for 12" records. If you play a lot of 7" singles it might be worth using a custom alignment optimised for tighter inner groove radii, like Stevenson or Rega geometry?
