  • Mark Levinson 33 set of monoblock amplifiers

    Mark Levinson 33 set of monoblock amplifiers

    King of the HIll! one owner These were top of the line for Mark Levinson and will drive any speaker. These are one owner 120V units. As of 1/19 only one pair available, 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

    Linn LK85 (2 available, price is for each)

    Linn LK85 tested 5/18 This model of Stereo Power Amplifier operates at 85W per channel up to 4 Ohms. The Linn amplifier is fully upgradeable, so users can update it when other components of their stereo systems are upgraded. There are four sets of speaker wiring on the Linn LK85, which makes bi-cabling convenient to put in place. The Linn amplifier is designed to conserve energy by going into sleep mode after 10 minutes of inactivity. This feature also preserves the circuitry, which can become damaged from frequently turning it on and off. The Stereo Power Amplifier is all black and is often referred to as the Black Box. There are no frills, and the basic look of the Linn LK85 allows it to go along with many other components of the stereo system without looking out of place.

    Krell KSA100 MK II

    Krell KSA100 MK II excellent cosmetics, there are some green markings in the picture which were removed. We can ship this in your desired voltage Description provided by highendclassics.com: The Krell KSA-100 Class A poweramplifier was the first stereo amplifier from Krell Audio Industries. At the start of the eighties Connecticut witnessed the birth of another highend audio company within its stateborders: Krell Industies. ‘Class A power to the people’ could have been one of the inspiring thoughts for Daniel D’Agostino chief designer of Krell Industries. Of course there were already some Class A designs in the domain of the power amplifier but most and probably all of them were confined to relatively small powerratings. Even the huge monaural Class A amplifier from Levinson, the ML-2’s, could only muster 30 to 40 Watts of power at 8 Ohms. Other noteworthy low power Class A designs were John Bedini’s 25/25 Class A amp and Jean Hiraga’s ‘Hiraga Classe A’. The only high power Class A amp in those days was a stereo 125 Watt Class A design from the SUMO electric company named ‘The Gold’ designed by James Bongiorno. D’Agostino envisioned and designed an array of high powered Class A amps in which the KSA-100 (abbreviation KSA stands for Krell Stereo Amplifier) was the most powerful stereo amplifier rated at 100 Watts Class A power at 8 Ohms. Technical The KSA-100 is a configuration of two completely separated amps only sharing the same huge chassis. Each amp has its own powersupply (one Avel Lindberg 1250 VA toroidal, two 40,000 uF Sprague or Mallory large cans per channel), driverboard and poweroutputsection. Another so called true dual mono design was the ML-3 from Levinson but this amp was biased in AB mode. To get rid of all the Class A generated heat from the outputsection Krell opted for forced cooling with Papst fans blowing down (the MK II version blew upwards in sync with the natural convection flow of heat) trough circular arranged heatsinks with eight TO3 encased powertransistors per channel attached to it. As a matter of fact the ‘The Gold’ from the SUMO company also used fans to cool down the amp. Using active cooling instead of natural convection kept size and cost in check because huge expansive heatsinks would be needed to drop off the 650 Watts continuous power consumption. Seven years later Krell did make huge convection cooled mono-amps as their reference series (KRS-100 & KRS-200) with the same Class A output but with a significant raise in price and weight compared to the forced cooled versions. Although Krell has always been strongly associated with Class A biasing it’s their ability to drive extremely tough loads, like the renowned amplifier killer the Apogee Scintilla (1 Ohm version) fullrange ribbonspeaker, that really illustrated the kind of DNA a Krell was made of. Only a few other amplifiers in this era, and most of them were amps with low powerratings, could drive speakers at such low impedences. Opening up the “hood ” of the amp gives you a strong visual indication of the ‘brute force’ method used to get an unflappable amp that could drive anything on the market then and today. D’Agostino’s assault on the highend poweramplifier market was very successful worldwide due to these first designs. After Levinson and Threshold, Krell established itself as a strong contender on the highend audio-market. Sound quality This range of first Krell designs redefined the meaning of bass-slam. The KSA-100 sounded much more powerful then it’s relatively modest rating of 100 Watts with acceptable levels of refinement in the middle and high regions of the frequency-spectrum. This stereo-amp is a alround workhouse that was often mated with tube preamplifiers from Audio-Research and Conrad Johnson. Not delicacy and transparancy as the best offerings from Levinson and Threshold but nevertheless highly recommend.
