QUAD 606 MKI Power Amplifier (Price Revised)
QUAD 606 Power MKI Amplifier
Description :
The Quad 606 Mk2 has a totally different sound to Quad 606 Mk1. The 606 Mk2 was a major improvement upgrade, having a totally different style of mains transformer, increased value smoothing capacitors and other circuit changes too. The Quad 606 mk2 has the top corners of the case "beveled at 45 degrees" and has the serial number above 21,000. Although several hundred 606 mk2's escaped in the old cases to use up stock on hand. If the serial number is above 19,500 and has a torrodial mains transformer inside, its a 606 Mk2.
The Quad 606 Mk2 still utilises Quad's patented current dumping technology. The dumping circuit in the Quad 606 consists of a very high quality low power Class A amplifier operating in parallel with a high-power Class AB amplifier. The low-power section controls the loudspeakers at all times, and the high-power section providing the muscle when called for. The Quad 606 Power Amplifier was originally launched in 1987 and essentially was a new improved version of Quad's 405 amplifier with extra oomph and a whopping 140 watts per channel into 8 ohms whose sonic improvement compared to original Quad 405-2 was significant. The Quad 606 power amplifier was used by many professionals and broadcasters as well as audiophiles possibly because of the sheer power of this amplifier coupled with Quad's reputation for producing solid well built amplifiers. The Quad 606 was a real power horse intended for driving the ESL-63 and professional speakers.
