Steep Angle Needed for a vdH Black Beauty

This vdH Black Beauty needs plenty of tilting forward. With its top level, the IMD is unacceptably high at about 12%. Lowering the arm high makes it even worse. Raising the arm on the SL1200G to the limit and slight improvements start to show. Eventually need to shim 3 pieces of cards in its front to get the numbers into the 2 to 3% range.

這個 vdH Black Beauty,調整到上緣水平時,IMD竟然高達12以上!降低一些更差,到14。SL─1200G的唱臂調到最高,稍微好一些到11左右。最後竟然前緣要墊3張名片的厚度,才到不錯的數字範圍。
