  • PS Audio Stellar M700 mono amplifier  CALL FOR PRICE!  TRADE-IN'S ACCEPTED

    PS Audio Stellar M700 mono amplifier CALL FOR PRICE! TRADE-IN'S ACCEPTED

    PS Audio Stellar M700 mono amplifier CALL FOR PRICE! TRADE-IN'S ACCEPTED The Stellar M700 mono amplifiers are a massively powerful engine capable of effortlessly driving demanding loudspeaker loads to concert levels. Stellar’s best. A pair of these placed on any loudspeaker brings forth the lush, rich and soul-satisfying power of two completely independent power blocks with headroom to spare. One listen to a hugely loud and complex musical passage effortlessly rendered by the M700 pair and you’ll know you made the right choice. Rated at 350 Watts into 8Ω and 700 Watts into 4Ω, the M700 combines the best of two worlds: ultra linear, high-current, Class D technology for the output stage; a discrete, Class A MOSFET based Analog Cell for the all-important input stage. The M700’s rich, warm, and engaging sonic character comes from the Analog Cell. Its powerful, authoritative control over the loudspeaker stems from its high current, ultra-low impedance Class D output stage. Stellar’s design imperative was to produce a truly musical sounding power amplifier that proudly competed with any amplifier under $5,000. Its designer, PS Audio engineer Darren Myers, took the challenge and set to work on a new concept—a hybrid that would combine the best of today’s technology with time-honored techniques leveraging PS Audio’s forty plus years of experience. The results are extraordinarily musical. Even from the earliest prototype we knew the Stellar power amplifier series was going to be something special. Stellar amplifiers never draw attention to themselves, a rare quality in amplifiers of any price. After hundreds of hours of tuning, voicing, and perfectionist tweaking, we were confident the ends justified the means. Audition the Stellar M700 pair and you’ll appreciate Myer’s dedication to musical truth without compromise. Learn More

  • Dynaco ST 150 power amplifier

    Dynaco ST 150 power amplifier

    Dynaco ST 150 power amplifier The Dynaco Stereo 150 is a basic two channel power amplifier employing all silicon semiconductors. They include 24 transistors, 2 zener diodes, 16 diodes, and 2 thermal sensors. The output circuitry is of the full complementary symmetry design. The entire amplifier, except for an input network, is direct coupled. It's measured distortion levels approach the threshold of much laboratory test equipment, not only at the commonly specified full power ratings, but more importantly at very low power outputs as well. This is the result of circuit techniques which eliminate any discernible crossover notch at low levels, and contributes to the Stereo 150's freedom from listening fatigue. It's accurate, uncoloured sonics have been achieved on a wide variety of loudspeaker loads, including electrostatics and multiple drivers with complex crossovers. The design of a very fine power amplifier implies the necessity of several protection techniques for the amplifier, and for the speaker load. In addition to the AC line fuse, four separate B+ fuses are supplied. Electronic volt-amp limiting ensures safe operation of the output transistors, and a thermal sensor mounted directly on each output stage reduces the input if high temperature occurs. An unusually large radiating area for the heat fins, which are coupled to an aluminium back panel, form a highly efficient heat sink. Speaker fuses protect the load. The Stereo 150 has been designed as two independent 75 watts (at 8 ohms) amplifying channels with a common power supply having a high degree of inherent regulation. In addition, where higher powers or higher volt-amp capabilities are required for lower load impedances, easy internal restrapping permits monophonic operation for 150 watts output (at 8 ohms). An accessory kit is planned at additional cost for two output meters and meter switching, which includes alternative inserts for the front panel. Specifications Power output: 75 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.25% Damping factor: 50 Input sensitivity: 1V Signal to noise ratio: 95dB Speaker load impedance: 4Ω to 16Ω Semiconductors: 24 x transistors, 2 x zener diodes, 16 x diodes, 2 x thermal sensors Dimensions: 14.5 x 13.75 x 7 inches Weight: 29lbs Learn More

  • Thule Audio SPIRIT PA100 power amplifier

    Thule Audio SPIRIT PA100 power amplifier

    Thule Audio Spirit PA100 power amplifier Thule Audio is a Danish company, specializing in audio equipment, ranging from basic entry level models, to models which are High End stuff. The product line is well thought out, and as we shall see, very rationally conceived and executed. For other reviews of Thule Audio products, look over the site. Both cases are virtually identical, and share the overall look of the entire Thule Spirit range. They are made of uncommonly thick, heavy and well finished cases, while front panels are made from 8mm thick aluminium, machined so that they have a gentle slope. In the center, one will find a "gold" knob in case of the preamp, and a decoration in case of the amp. The preamp has an alphanumeric display above the knob, which provides the user with all relevant information on power on, volume and input status in red LEDs. All this is fully remote controllable, and a remote control unit is supplied. The power amp is a very simple affair, with only a red LED power on indicator on its front side. Both units have rocker power on/off switches at the back, as they're intended to be left in standby mode all the time. [Thule PR 100 inside view] Both units share much more common componentry that I would have imagined. Both use toroidal power supplies, where the amp's toroid is rated at 500VA, while the preamp's toroid is rated at 300VA. No, you're not seeing things, it's not a typo error, I did say 300VA. That's enough for a 2x75W/8 Ohm power amplifier, let alone a simple preamp. In fact, the preamp is EXACTLY the same as the IA60 integrated amplifier, minus the power amp circuitry and heat sinks. Put another way, the preamp consists of the preamp section of the IA60 integrated. Hence the 300VA toroidal transformer - that's what they use in IA60 (see review on this site). The power amp, on the other hand, is once more the same board, but minus the preamp circuitry and with heftier power supplies - bigger transformer, and 4x10.000uF capacitors, instead of just 2x10.000uF. This is no accident, this is rational thinking. Use the same board, use the same case, use the same power supplies and you increase the numbers of your serial production, thus pushing the cost per unit down. The only thing that spoils the show is the preamp's price - it's simpler than the integrated model, but it's not only not cheaper, it's actually somewhat more expensive. That is most odd, I must say - probably for "complex marketing reasons" (a phrase I first heard in the early seventies, and it's gotten worse since then). You still have 5 line level inputs, with no option for a phono RIAA board of any kind. You still don't have a headphone output - somebody should inform the Scandinavian audio industry that headphones have been invented some decades ago, they seem to have collectively overslept that event. As usual, all input and output sockets are gold plated. Like elsewhere in Thule's product portfolio, volume and balance are controlled by a ladder of laser trimmed resistors, contained within an LM1792 digital volume control, a good point - no mechanics, no wear and tear, no aging, unparalleled precision. The amp is rated at 2x100W/8 ohms and 170W/4 Ohms - that should be enough for most of us. It has an RCA Cinch and a balanced XLR input, just as the preamp has the same outputs. Acting on logic and Thule's recommendation, I used balanced lines to link the two, except when using other units. Learn More

    Crown Reference 1

    Crown Reference 1 ships to you in 6/2017 Reference I (120 V, 60 Hz models) The Crown® Studio Reference I power amplifier shall be a solid-state two-channel model employing multi-mode (AB+B) grounded bridge(TM) output circuitry with a variable impedance (VZ) power supply for each channel. The outputs shall be switchable as stereo, bridged-mono or parallel-mono modes of operation. The bridged-mono mode shall bridge the outputs to provide increased output voltage. The parallel-mono mode shall parallel the outputs to provide increased output current. The output impedance of each channel shall be less than 10 milliohms in series with less than 2 microhenries in stereo mode. The variable impedance power supplies shall reduce unnecessary voltage across the output devices by automatically switching to a parallel mode when less voltage is required by the output circuitry and to a series mode when more voltage is required. The amplifier shall contain protection circuitry which limits the drive level placed on the output devices before their SOA (Safe Operating Area) is exceeded. This protection circuitry shall calculate the instantaneous voltage across and current through the output devices while factoring in their simulated junction temperatures to predict how close they are to their operating limits. This protection will be called “ODEP.” The amplifier shall contain controlled slew-rate voltage circuitry to protect it against radio frequency interference burnouts. It shall also be protected from current overload at its output stage. The slew rate of the amplifier shall be greater than 30 volts per microsecond in stereo mode. The amplifier shall temporarily go into a stand-by mode if its power transformer becomes excessively hot and shall automatically resume normal operation once it has cooled to a safe operating temperature. Front-panel controls shall include an enable on/off switch and a detented input level control for each channel. Rear-mounted controls shall include a ground lift switch to isolate the signal ground from the chassis ground, a switch which selects between stereo, bridged-mono and parallel-mono modes of operation and a reset switch for the AC mains circuit breaker. Internal controls shall include an input sensitivity switch to select between 0.775 V, 1.4 V or a fixed voltage gain of 26 dB for full rated output. A Crown P.I.P. and P.I.P.2-compatible expansion connector shall be provided behind an access panel in the rear to accept auxiliary input modules. It shall be fully compatible with the Crown IQ System. Front panel indicators shall include an amber power enable indicator, an amber ODEP protection system indicator for each channel which shall normally be illuminated to confirm the availability of reserve thermodynamic energy and which shall dim in proportion to limiting when the power demands of the output stages have been exceeded, a green IOC indicator for each channel, and a green Signal indicator for each channel which shall normally flash at moderate intensity to show the presence of an audio signal. The power amplifier shall meet or exceed the following performance criteria. Input sensitivity for rated output: 26 dB voltage gain (unbalanced). Rated FTC output in stereo mode with less than 0.1% THD: 780watts per channel (20 Hz to 20 kHz) into 8 ohms. Hum and noise: at least 120 dB (A weighted) below full rated output power. Phase response: +5 to –15 degrees from 20 Hz to 20 kHz at 1 watt. Frequency response: 20 Hz to 20 kHz, 0.1 dB at 1 watt into 8 ohms per channel in stereo mode. Damping factor: greater than 20,000 from 10 to 200 Hz into 8 ohms. Intermodulation distortion (SMPTE): less than 0.005% from full bandwidth power to 78 watts rising linearly to better than 70 dB at 20 kHz. Harmonic distortion: less than 0.02% at rated low-distortion 1 kHz power. The amplifier shall be safe when driving any kind of load—even highly reactive ones. The power requirements shall be 120 VAC at 60 Hz. At idle, the amplifier shall draw 90 watts or less. The amplifier chassis shall be constructed of steel with a durable black finish and shall be designed for flow-through fan-assisted ventilation from the front panel to the side panels. The amplifier shall have an aluminum front panel with super-gloss Imron finish and Lexan overlay. The dimensions of the amplifier shall allow for 19 inch (48.3 cm) EIA standard (RS- 310-B) rack mounting. The amplifier shall be 7 inches (17.8 cm) tall, 16 inches (40.6 cm) deep behind the rack-mounting surface, and 2.75 inches (7 cm) in front of the rack-mounting surface. The amplifier shall weigh 60 pounds, 11 ounces (27.6 kg) and shall have a center of gravity approximately 6 inches (15.2 cm) behind the front panel. The amplifier shall be designated the Crown Studio Reference Learn More

    Balanced Audio Technology VK-6200 three channel version

    Balanced Audio Technology VK-6200 3 channel verison Balanced Audio Technology’s groundbreaking VK-6200 multichannel power amplifier satisfies the demands of the most sophisticated home-theater system while simultaneously playing music with the characteristic open, uncompromised sound that has become a BAT hallmark. Until now, the compromises required to fit several channels of amplification into a single chassis have restricted sound quality—even for high-end components. Competitors’ best designs often require an expensive commitment to buy a “fully loaded” configuration. The VK-6200 is different. Its modular design accommodates up to six discrete 200-watt amplifier modules. Fully balanced, the VK-6200 can also be purchased in any configuration—from two to six channels. Output per channel at 8Ω/4Ω 200W / 400W Conversion to Mono? 2,3,4,5 or 6 channels Output in Mono Configuration 8Ω/4Ω n/a Frequency Response 2Hz to 180kHz THD at full power 0.1% Input Impedance 50 kΩ Gain (Nominal into 8Ω) 23dB Balanced / 29dB Single-Ended Tube Complement n/a Number of Power Cords 1 Remote Control 12V Trigger Input & Output Power Consumption (Idle/Full Power) 80W/1800W (w/ 6 channels) Dimensions (WHD) Inches 19" x 10.5" x 23" Dimensions (WHD) mm 480 x 280 x 580 Weight 100 - 180 Lbs Learn More

  • Linn AV 5105 Stereo Power Amplifier

    Linn AV 5105 Stereo Power Amplifier

    Linn AV 5105 Stereo Power Amplifier, tested 5/18 The Linn AV 5105 Stereo Power Amplifier is intended for use in high performance audio and audio/video systems. It combines high output power, ruggedness, and ease of use with our passion for quality. It draws on years of experience of designing and making high quality audio power amplifiers. Inside the compact case are two completely independent electrically isolated channels with fully regulated power supplies giving ‘dual mono’ performance. The signal path is DC coupled and servo controlled for the lowest distortion, cleanest, least colored sound. The output stage is highly derated for cool, reliable operation, and the protection circuitry protects extensively against accidents or abuse. A signal sensing circuit detects the presence of audio above a very low level and turns on the main power supplies to the amplifier, bringing the power amplifier channel from a very low standby power consumption to full operation. It reverts to the standby condition a few minutes after the input signal disappears. This is particularly useful in multi-channel surround sound systems. The AV 5105 accepts the Linn active crossover modules, automatically detecting their presence and switching them in circuit as soon as they are plugged in. This makes playback system upgrades easy. Type Two fully independent channels, isolated from each other and chassis (earth). Fully regulated dual power supplies per channel. Inputs Dual RCA Phono (Line in/out) Outputs Four pairs per channel Protection Fully protected into any load; overload, over-temperature, full short and overdrive protection Remote control Signal-sensing auto switch-on/off for energy conservation or remote operation Output power 100W/channel/8Ω, 200W/Channel/4Ω Input signal 1.05V rms for maximum output Output voltage 28.3V rms maximum Gain x27 (28.6dB) Input impedance 4700Ω Frequency response (-3dB) 2Hz-50kHz Output offset 150μV rms Mains supply 220V–240V T3.15A antisurge, 100V–120V T6.3A antisurge Standby power consumption Learn More
