Jag läser innantill i beskrivningen för min RIAA förstärkare det står:
"The substitution of the model 104 for the step-up transformer, not only provides RIAA equalization, but significantly reduces the frequency discrimination, phase shift, ambient pick-up, and impedance limitations associated with, and inherent in, transformers. In addition, the extremely low impedance output of the model 104(3 ohms) and the Ortofon cartridge(2 ohm) reduces, by more than two orders of magnitude, the ambient hum pickup and capacitive high frequency attenuation found in normal high impedance shielded cable connctions. Thus, for the first time, long cable runs may be used between cartridge and subsequent amplifies without adverse effects."
