Choosing a MC phono preamp for my new cartridge

I may have asked this before, but do you teach?

No. I appreciate your comments; I put myself through engineering school by repairing consumer electronics. I somehow seemed to have a knack for explaining technical issues in layman's terms so I got asked to do that a lot when customers picked up their repaired equipment.

I have to say Ralph that I always always learn something new from your posts, but I you got me confused here.

Are you saying that the loading with a switch is worse than loading direct with resistors in the circuit because of the electrical condition of the switch

Or you are saying than with the switch you have not the the granular adjustment you could have with resistors and you have to go through steps of loading that might not be optimal

By the way off topic but I learned recently that for the MP-1 to sound perfect in my rig needs 2, ideally 3 hours warm up. With 3 hours warm up it gets completely out of the way, totally different than for example after only 1 hour, on MY system.

Neither. I am saying that if a loading switch is present, its an indication that the designer of the preamp did not take the electrical peak that is always present into account. He may have even been thinking that the loading is there to prevent ringing of the cartridge, which it doesn't (the inductance of the cartridge is so low it simply won't ring at audio frequencies).

use it in balanced input mode for best exp
