Audio Research LS-25 (mkI)
Brand: Audio research
The Audio Research LS-25 (mkI) is a highly regarded integrated amplifier that was produced by the American audio company, Audio Research, in the 1970s. It is a tube-based amplifier that delivers a warm and lush sound with impressive clarity, detail, and dynamics for its class. The LS-25 (mkI) is designed to drive medium to high-impedance speakers and is known for its low-level detail, smoothness, and harmonic richness. Its input stage uses hand-selected JAN (Japan military) tubes, while the output stage uses ED30 (a sixties-era high-performance version of a tube famously used by Western Electric and Bell Labs) tubes. Some notable features of the LS-25 (mkI) include a detachable AC power cord, adjustable input levels, and a built-in polypropylene frequency compensation capacitor. The LS-25 (mkI) is considered a classic and sought-after piece from the golden age of tube audio, and it remains popular among audiophiles and collectors today.
