End of lp distortion. What does it sound like

Typically it's time to replace cartridge.

Some alignment schemes are better than others at reducing end of LP mistracking. I believe the Stephenson specs are intended to address this. Not sure what protractor you are using or what specs your Mint will be based on.

I have a Scout with a new DV 20x2l so it's not worn. As for AS there is only the natural twist of the wires, I did not add any more. I have not messed with VTA or VTF yet.

Your new DV cart is a good one. Since its new, start at the upper end of the recommended tracking force - between 2.1-2.2g. See if that helps. When the mint arrives, be patient and dial it in then.

The Mint Best Tractor is the way to go; I have one. But, it's really important to use the Stevenson geometry to avoid inner groove distortion. This is a highly debated subject because on paper and in theory the Baerwald geometry produced less tracing error earlier on the LP side. However, the Stevenson alignment geometry is more modern than the Baerwald, and puts the inner null point (where the stylus is tangent to the groove) on the industry's standard inner groove limit so it produces 0 tracing error where the grooves are the smallest, slowest, and most suseptible to AUDIBLE distortion. This is a case where Baerwald is better in theory and on paper, but in practice Stevenson is better. The increased tracing error induced by the Stevenson geometry is where the grooves are longer, traveling faster, and therefore not be as audible. Yip at Mint can make you a custom protractor for your table with the Stevenson geometry and I highly recommend it. You'll have the best case scenario with his protractor and the Stevenson geometry. Not every record has grooves cut to the maximum inner groove limit, but for the ones that do, why not have them sound the best they can... which will be with the Stevenson geometry.
