Thanks @bkeske - was having a hard time finding a picture to illustrate. Good to hear that you are not having any issues. As Lewm indicated, not every tonearm/table may have issues with recessed armboards. Not to cloud things, but there also is a platter to plinth or top of armboard height requirement that most tonearms require.
