Integrated amplifiers - Hifiverse audio equipment catalog

The new NuPrime Class A+D hybrid amplification technologies deliver the essence and warmth of Class A amplification, as well as the efficiency and speed of Class D technology in an environment of immeasurable noise. The spacious, transparent, dynamic and luxuriously textured sound stage of the IDA-8 inspires confidence.

The amplifier is equipped with a built-in phono corrector for working with the pickup heads with a movable magnet (MM) with advanced input resistance and capacitance settings. The phono corrector circuit uses MUSES 8820 operational amplifiers. The input selector here is a relay one, which ensures minimal interference during switching. The volume control is stepwise, with 99 levels of gain.

The device is equipped with a separate AV input. Users will be able to select a fixed or variable gain on the line output. This will come in handy when the 3510 model is used in conjunction with the front-facing acoustics of a home theater. To ensure a "low noise level on the power supply buses to the amplification stage," the device received a hybrid power supply circuit.

The Exposure 2510 Integrated integrated amplifier has a concise design, but it takes into account everything that can affect the sound quality. The device is equipped with a powerful custom-made toroidal transformer capable of delivering a total power of up to 200 watts. This is enough to supply power to the terminal amplifiers, which produce 75 watts per channel in the 8th. The amplifier is equipped with dual output terminals, providing for the possibility of connecting speakers according to the bi-wiring scheme.

The Luxman L-595A SE integrated amplifier provides direct selection of the active input via large square keys. The volume, tone, and channel balance controls are rotary. Moreover, the gain level knob is illuminated with a soft LED light. The case is covered from above by a 6 mm thick aluminum plate with ventilation holes for efficient heat dissipation.

The L-505uXll received the latest version of the proprietary negative feedback circuit, ODNF4.0, (the L-505uX had version 2.3), with improved high-frequency performance and reduced output impedance. The output stage of the preamplifier has the same discrete element buffer circuit as the flagship C-900u, which improves the ability to efficiently work with the power amplification section while maintaining the purity of delicate musical signals.

The Luxman L-505Z integrated amplifier, like the older L-509Z and L-507Z models, implements proprietary LIFES technology, which is an integral part of the Luxman next-generation amplifier circuitry. LIFES (Luxman Integrated Feedback Engine System) is based on the ODNF (Only Distortion Negative Feedback) feedback concept, which provides excellent performance without feeding any musical input signals back to the input of the main amplifier.

The Luxman L-550AX II is a modified version (Mark 2) of the L-550AX amplifier, released in 2011. The L-550AX II debuts with a precision electronically controlled LECUA attenuator and the latest version of the proprietary Distortion-Only Negative Feedback circuit, ODNF 4.0, which are used in Luxman's highest-end amplifiers.

The Luxman L-507UX Mark II is equipped with a new LECUA 1000 attenuator and a buffer circuit on discrete elements in the output stage of the preamplifier, and is also equipped with a new version (Version 4.0) of the LUXMAN ODNF feedback circuit (with distortion–only Negative Feedback).

The Luxman L-590AXII is a new flagship in the proprietary integrated amplifier series, operating in the pure A-class. The device continues the evolutionary line of the L-590AX and embodies the best practices of the company over the past fifty years.

The Luxman L-507Z integrated amplifier combines advanced technology and rich functionality, going far beyond its price segment in terms of acoustic capabilities, Luxman claims. The novelty is the first model in the Z series, which the manufacturer calls innovative. The company's pretentiousness is based on the successor to the ODNF feedback circuit, which has been present in Luxman amplifiers since 1999. It was replaced by the LIFES scheme, developed through painstaking research. The technology debuts in the L-507Z.

The device also uses the original LUXMAN ODNF feedback circuit (with negative feedback only based on distortion) and a power supply with independent storage capacitors for the left and right channels, as well as many circuit solutions commonly used only in the highest-end models, which together ensures high-quality music playback.

The Luxman L-509Z power amplifier consists of three cascades of four parallel transistors operating in a push-pull mode. The output power declared by the manufacturer is 220 watts when operating on a load with a nominal resistance of 4 ohms for each channel.

The flagship of the new generation Z series, the L-509Z, has evolved into something that goes beyond the concept of integrated amplifiers. For the first time, the amplification feedback mechanism of the new generation "LIFES" is used simultaneously in the circuits of the preamplifier and the power amplifier. The volume control part is equipped with a new "LECUA-EX" mechanism, which suppresses the deterioration of sound quality and provides an accurate sense of operation. The "one case, separate" concept, which aims to create the perfect all-in-one amplifier, has reached unprecedented heights.

The LUXMAN SQ-N150 integrated amplifier has three line inputs and a phono corrector input, which is compatible with both MM (movable magnet) and MC (movable coil) cartridges. The RCA connectors are gold-plated and extended by as much as 18 mm to accommodate high-quality cables. To minimize crosstalk between the left and right channels, the same input selector chip (IC) is used as in the top-end LUXMAN C-900u amplifier.

The LX-380 represents a new era in the development of the "Golden 38th" Classic series of integrated tube amplifiers from Luxman. Designed for exceptionally deep insight into recordings from audio sources of various times and genres, the Luxman LX-380 is equipped with LECUA (Luxman Electric Controlled Ultimate Attenuator), a computerized signal attenuator that can carefully reproduce the dynamism of any concert, and the power amplification cascade scheme allows you to unleash the rich musicality of 6L6GC type output lamps.

The Mastersound Gemini stereo amplifier. Push-pull integrated amplifier, class "A", Automatic Bias, 2X50W (pentode), 2X25W (triode), 2xESS802, 4xKT150, XLR inputs, remote control.

The MastersounD Evo 845 is a top–class integrated tube amplifier with a remote control. Its output power is 2 x 50 watts, and its net weight reaches 53 kg. It has 3 line inputs and one Direct to RCA with gold-plated connectors. Like all Italian MastersounD amplifiers, the integrated Evo 300B amplifier operates in pure Class A.

The MastersounD Evo 300B is a top–class integrated tube amplifier with a remote control. Its output power is 2 x 24 watts. It has 3 line inputs and one Direct to RCA with gold-plated connectors.
