Question- I don't have the ability to change VTA or azimuth on the fly which I understand is recommended for Micro Ridge , MicroLine or similar stylus profiles.Then again I don't play LPs very often- maybe 4hrs per week. So is a spherical- aka Denon or elliptical -aka Denon 103 OK? Kenwood KD500 w/ Grace 707 arm. I have those carts.
