The Grado will hum with the Classic due to lack of shielding.
Dynavector Karat or Grado Statement Reference 1
I have been using Dynavector's 17D3 MkII on my VPI Classic TT (w/Krell, amp,pre,ref phono-B&W 802N) but have read the Grado is very musical in the midrange without loss in the high or low frequency. I read Harry of VPI swears by the Sonata but I would be willing to spend double possibly for my system. The Dynavector is a $1K acrtridge with great sound and reviews. Would The Grado be an improvement or am I possibly taking step backward?
