Moonachie, New Jersey 07074 Perhaps the most remarkable feature of the preamplifier circuit in the SX-1250 is the unheard-of phono overload level of half a volt (500 mV). That means there's no magnetic cartridge in the world that can drive the preamp to the point where it sounds strained or hard. And that's the down fall of more than a few expensive units. The equalization for the RIAA recording curve is accurate within ±0.2 dB, a figure unsurpassed by the costliest separate preamplifiers. THE CLEANESTFM RECEPTION THERE IS. Turn the tuning knob of the SX-1250, and you'll know at once that the AM/FM tuner section is special. The tuning mechanism feels astonishingly smooth, precise and solid.
