I understand the wife factor. In the case of the XP-25 it was she who wanted me to get rid of my tubed gear, so I had prior approval. I went to TMR and found the Pass Labs phonostage. I had an XP-25.Pass Labs preamp of the same vintage, and neither of them seem to have been much improved upon by the Pass Labs XP-32 over my XP-30 or the Pass Labs XP-27 over my Pass Labs X-25.
I begin with the tone arm parallel to the record, but lift a bit for extra treble. I cannot drop the arm beyond parallel because my tonearm is parallel to the record at the lowest setting.
Thanks for the information. That makes it a bit clearer. In the end, though, I just go by my ear. Although, I can't hear things right away. It can take me months. I'm pretty dialed-in now to the changes made by impedance and capacitance. I know capacitance is not supposed to make a difference with my MC cartridge, but it does. The general concensus is to set capacitance to 100 with a moving coil cartridge, but to my ear 200 sounds better. 320 is too zipped up. Too weighty or however one might put it.
