The Onkyo M-5890 (M-588) from 1992 delivers an exceptionally clean and authoritative audio performance by leveraging its twin-mono construction to virtually eliminate crosstalk, resulting in a wide, pinpoint-accurate stereo image. Its high-current 3-parallel push-pull output stage provides the muscularity needed to grip demanding speakers, ensuring deep, controlled bass and effortless transients even during complex musical passages. The integration of the Super Balance Circuit and Double Super Servo minimizes distortion and noise floor, allowing micro-details and subtle textures to emerge with lifelike clarity. Thanks to the LASER transformer’s shielding, magnetic interference is neutralized, preserving the purity of the signal for a warm, musical character that remains transparent across the entire frequency spectrum. The Onkyo M-5890 delivers a continuous power output of 200 watts per channel into 8 ohms, with dynamic power reaching an impressive 750 watts at 2 ohms to accommodate low-impedance loads. Precision is further refined by a 70μm thick copper foil circuit board and a custom-made detent volume control featuring gold-plated sliders and a high-internal-loss brass shaft to eliminate micro-distortions across the entire frequency range.

The Onkyo P-3890 (P-388) preamplifier is the critical counterpart to the M-5890, designed to establish a totally balanced configuration from source to output. It mirrors the amplifier’s high-end architecture with its own dual-mono structure and "Super Balance" circuitry, featuring a double-differential input and double-servo design that eliminates noise induced during transmission. By utilizing two dedicated AEI LASER transformers—one specifically for line sources and another for phono stages—the P-388 ensures that delicate signals remain unpolluted by power supply fluctuations. For vinyl enthusiasts, the P-3890 offers a sophisticated phono section with independent MM and MC circuits, built using discrete components rather than integrated circuits to preserve a pure, analog warmth. Its design philosophy of "simple is best" omits standard tone controls in favor of a direct signal path, which results in stunning dynamic contrasts and authentic detail. When paired with the M-5890 via XLR balanced connectors, this duo functions as a singular, cohesive system that delivers superior bass slam, cleaner midrange, and a more expansive soundstage than previous Integra models. Size (W/H/D) 466x90x418mm | Weight 8,9kg
