Усилители Audio Research — винтаж и современные

ТАААК написано что The “Impedance” switch isn’t really that. It’s a resistance switch, selecting different values of cartridge loading for MM cartridges and a variety of MCs. The preamp gain, by the way, is high enough, and its noise low enough, that it will work fine with any but the lowest-output MC cartridges, without the need for a signal-fouling step-up device. Thus, there is no sound quality sacrificed through one’s choice of MC rather than MM cartridge.

или я что то не так понял?
