Pre-pre-amp".>

many outboard phono preamps are capable and switchable between mc and mm. a pre-preamp boosts the signal from a mm preamp so the mc can be heard at about the same level as the mm.

i had a terminology disagreement here or at aa with another fellow regarding line stages which are now erroneously called preamps. we ended up having to agree to disagree.

my pre-preamp provides input impedance selections via plug in resistors. i am also borrowing an ortofon transformer which obviates the need for impedance matching. vinyl really is a hobby with experimentation involvement. lotsofun.
