Audio Research HD-220 Hybrid Stereo Power Amplifier

General : Heavy and excellent-sounding Hybrid Tube / Transistor power amplifier. This Audio Research HD-220 has been fully restored to like-new condition by Audio Research USA, including new driver tubes.

Technology : The Audio Research HD-220 features a tube driver stage that drives the latest Thermo Track transistors. The result is a typical beautiful tube sound with a generous output power of 2 x 220 Watts at 8 ohms and 2 x 400 Watts at 4 ohms. Sufficient for virtually any speaker. The driver tubes are therefore new and have zero hours on the clock. Audio Research specifies the tubes for 4000 hours, and they are relatively affordable. The Audio Research is the perfect power amplifier for lovers of the famous Audio Research sound quality, but who need more power than fully tube-equipped power amplifiers. Reliability is also higher.

Sound : The Audio Research HD-220 exhibits the typical Audio Research sound quality. Very much musicality and authority. A very analog sound picture, lots of dynamics and warmth, and a quiet overall sound. Not nervous at all. The large work is reproduced by the Audio Research HD-220 with great ease and much pleasure. This Audio Research HD-220 is now available to listen to at Ohm-Audio bv.
