"...the system is powerful, engaging and very listenable, even when pumping the bass cones as though there was no tomorrow." Each channel's +/- 80 Vdc B+ and B- supply rails use high-speed rectifier diodes and two Rubycon custom-made 10,000uF electrolytic filter capacitors, chosen for their low Equivalent Series Resistance (ESR), dielectric absorption and resistance to high temperature. Lightning-fast (60 MHz) transistors respond instantly to complex demands in the musical signal, virtually eliminating distortions that occur with "slower" transistors. I just tossed that issue over the weekend and as I recalled it was within specs, think it missed the 5 channel driven by 2 watts at 0.5% distortion. The Parasound product is very hard to beat for the money. ", Alta Fidelidad (Spain), August 2003 Parasound, based out of San Francisco, was founded by a former audio retailer Richard Schram. They currently have the 3b3 on sale for … Pure Class A operation provides the purest sound. The Halo A 52+ has a custom 1.5 kVA encapsulated toroid power transformer with independent secondary windings for each channel and 100,000 µF power supply filter capacitance.

I’m not sure how much demand there actually is for three-channel amps, but I do use one to drive the center and surround speakers of my home-theater system, so I can see the utility of the A 31. "Even in the biggest 'encounters' the Parasound never lost imaging, and even the strongest explosions or deepest bass attacks of a kind like 'Star Trek' could not distress them at all." With 44% more power output than its predecessor, the A 52+ will drive just about any speaker with even greater explosive power and captivating grace. Electrostatic speakers are notorious power hogs, and the Martin Logan Summits are no exception. Each channel's output stage employs four pairs of high current (15-ampere) bipolar transistors to insure long-term reliability, even with continuous high power operation and challenging speaker loads. This advanced circuitry never needs adjustment or maintenance. "Now about sound, it is powerful, well balanced and not deformed on the dynamic range edges. This sale is offered to anyone Club Polk member who … Encapsulating this massive power transformer in an epoxy-filled steel canister assures ultra-quiet performance. It's my understanding, that the Parasound A52+ (Halo) five-channel amplifier is based on their highly successful A 52 amplifier. Diapason D'OR Award Address. Parasound power amplifiers incorporate ingenious and fast-acting DC servo circuits, completely eliminating the need for coupling and blocking capacitors. It also makes possible the use of passive cooling and avoid fans, whose noise can be heard over the music. Full power is rated all the way down to 5 Hz for unrestricted low-end bass. The reality of sound sometimes seems unbelievable - Ian Holm's voice in 'Fifth Element' is just amazing. Please provide a valid price range. I currently have and will use the … Polypropylene and mica capacitors are used extensively for their superior linearity and low dielectric absorption. Looking to replace my Yamaha MX-A5000 with one of the above 5 Channel Amplifiers. It uses hand-matched JFETs for the input stage, hand-matched MOSFETs for the driver stage, and beta-matched 15 amp, 60 MHz bipolar output transistors (three pairs per channel). - Ghislain Prugnard, What Hi-Fi (Russia), January 2004 Price. Parasound says that the Halo A 31 was developed in response to the increasing demand for a high-performance, high-power, three-channel amplifier. These precision input JFETs are also cascaded to produce the current necessary to drive the MOSFET drivers in the following stage. Please comment! Legendary designer John Curl designed the critically acclaimed JC 1, JC 2, Halo Integrated, and other no-compromise Halo components. - Miguel Riera, "The Parasound Halo A 52 is a magnificent performer and should be considered by any audiophile looking for multi-channel audio performance." > 63 dB at 20 kHz, Input Impedance: Unbalanced: 47 kohm ; Balanced: 94 kohm , 47 kohm per leg, Input Sensitivity for 28.28 V Output into 8 ohm : Unbalanced: 1 V; Balanced: 1 V per leg; Total Gain: 29 dB, S/N Ratio: > 112 dB, input shorted, IHF A-weighted; > 102 dB, input shorted, unweighted, Power Requirements: Standby: 1 Watt; Idle: 125 Watts; Maximum: 1500 Watts, Dimensions The chassis is made of heavy gauge steel to safely house the internal circuitry.
