The Quad 606 Power Amplifier is another classic amplifier design from Quad utilising their patented current dumping technology. Essentially a current dumping circuit like the Quad 606 Power Amplifier consists of a very high quality low power class A amplifier feeding a high power low quality amplifier which is used when required. 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 also very popular with professional audio people 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 Power Amplifier was discontinued in 1997 to make way for the Quad 707 power amplifier which was another current dumping design that improved slightly on the Quad 606 and was one of Hi-Fi World's recommended amplifiers at that time.

Rotel RB-1050 Ideal for demanding custom installations, the ultrastable RB-1050 combines audiophile sound quality and “bullet-proof” circuitry. A multi-mode amplifier, the RB-1050 develops 70 watts per channel for stereo reproduction. Individual sensitivity adjustments and “auto on” signal sensing circuitry allows use with a variety of distribution devices or processors. Buffered line level outputs allow multiple amplifiers to “daisy chain” from a single source. The toroid-based power supply and high damping factor ensure precise control of virtually all speakers. 12 volt “trigger” jacks and a detachable AC cord make this amplifier ideal for remote operated distributed audio systems. A front panel LED array shows clipping and protection modes for quick system analysis. Power Configurations: 2 x 70 watts Watts/Channel: all channels driven, unbridged, 8 ohm load, 20 to 20k Hz, 0.06% THD 70 watts THD (20-20,000Hz): cont. rated power one-half rated power one watt per channel 0.03%, maximum 0.03%, maximum 0.03%, maximum IM Distortion (at rated ower, 60Hz:7kHz = 4:1): 0.03%, maximum Damping Factor (8 ohms): 500 Input Sens. / Impedance: 1.0V / 33 kohms Frequency Response: 10-100kHz (±1dB) S/N Ratio (IHF A): 116dB Power Consumption: 250 watts Dimensions (W x H x D): 433 x 92 x 334mm 17 1/8 x 3 5/8 x 13 1/8" Front Panel Height: 80 mm, 3.1" Learn More

One set is in excellent condition. http://www.marklevinson.com/downloads/products/prod_186_634722476892713969_no33_om.pdf The Nº33 Reference Mono Power Amplifier uniquely combines extraordinary power delivery with effortless control and unparalleled refinement. Rated at 2,400W continuous into 1-ohm loads, it is the most powerful high-end amplifier in the world. The Nº33 incorporates two 2.45 kVA low noise toroidal transformers in a fully balanced power supply. In this design, there is a separate power supply (each with its own power transformer) for both the inverting and non-inverting halves of the amplifier. Twelve 39,000 μF low ESR capacitors are used in each amplifier. The power supply of each Nº33 provides almost 1⁄2 a Farad of capacitance and 1200 Joules of energy storage. Heavy oxygen-free copper bus bars enhance the efficiency of power distribution within the amplifier and eliminate variances introduced by the wiring harnesses, etc. more commonly found even in high performance amplifiers. High frequency power supply bypass is accomplished on individual PC boards by a total of 56 components of several film types. The resulting uniformly low power supply impedance seen by the various circuits within the Nº33 lays the foundation for both the massive power and the extraordinary finesse that characterizes this amplifier Learn More
