IOTAVX AVXP 7-230

The AVXP 7-230 stands as the flagship of the IOTAVX amplifier range, a British brand renowned for its uncompromising approach. Delivering a colossal 230 watts per channel at 4 ohms when all seven channels are driven simultaneously, this amplifier offers performance typically reserved for devices three to four times more expensive. Its design focuses on the essentials: high-quality amplification, carefully selected components, and robust construction, without unnecessary frills. Designed to satisfy the most demanding audiophiles and cinephiles, the AVXP 7-230 stands out for its ability to reproduce the most delicate musical passages as well as the most dynamic action scenes with remarkable precision.

Masterful Power Serving Sonic Dynamics

The AVXP 7-230 first impresses with its considerable power reserve. Capable of delivering 150 watts per channel at 8 ohms when all channels are driven, it climbs to 230 watts at 4 ohms. This generosity allows it to power even the most demanding speakers without ever showing signs of weakness.

At the heart of this power are two massive shielded toroidal transformers, totaling a power supply capacity of 2,640 watts. This oversized power architecture ensures exemplary stability, even during the most intense passages or sudden explosions in your favorite movies.

To handle dynamic peaks, the amplifier is equipped with an impressive array of filter capacitors offering a total capacity of 280,000 microfarads. This instant electrical reserve allows for faithful reproduction of percussive drum attacks or cinematic explosions without any dynamic compression.

Uncompromising Technical Design

The AVXP 7-230’s design approach prioritizes component quality and audio signal integrity. Its robust steel chassis not only provides a professional look but also helps shield internal circuits from electromagnetic interference.

Its high-gain design reflects careful consideration of real-world amplifier use. This feature is particularly advantageous when paired with AV receivers whose preamp outputs offer limited voltage. Despite this high gain, the amplifier maintains remarkably quiet operation, with an excellent signal-to-noise ratio of 112 dBA.

The extremely low distortion rate (≤0.015% at maximum power) ensures faithful reproduction of the original signal, without coloration or artifice. The extended bandwidth (10Hz to 35kHz) guarantees full reproduction of the audible spectrum and beyond, preserving the subtle harmonics that contribute to realistic sound.

Well-thought-out functional details complete the package, such as the power LED that automatically dims after startup to avoid disrupting the visual experience in a darkened room, and a configurable remote trigger function.

A Balanced, Reference-Grade Sound Signature

The AVXP 7-230’s sonic character is distinguished by its balance between analytical neutrality and engaging musicality. Listening tests reveal a harmonious tonal balance, combining energetic attack, solid bass, body in the midrange, and detailed yet non-aggressive highs.

Its ability to create a precise three-dimensional soundstage enhances immersion in both cinematic and musical content. Instrument or sound effect localization is remarkably accurate, while the amplifier manages to recreate a convincing sense of space.

Unlike some high-power amplifiers that only shine at high volume, the AVXP 7-230 retains its qualities even at low listening levels. This versatility makes it an ideal companion for all types of use, from discreet nighttime listening to full-power cinema sessions.

Flexible and Practical System Integration

The AVXP 7-230 adapts to a wide variety of setups thanks to its comprehensive connectivity options. It features both unbalanced RCA inputs and balanced professional XLR connectors, allowing optimal integration with all types of preamplifiers.

It is the ideal partner for the IOTAVX AVX17 multichannel preamplifier but integrates just as effectively with any preamplifier or AV receiver equipped with preamp outputs. This flexibility allows you to either build a complete IOTAVX system or significantly upgrade the performance of existing equipment.

For particularly ambitious home theater installations, it is possible to pair two AVXP 7-230 units to create a configuration of up to 9.1.4 or 7.1.6 channels, thus offering a reference-grade three-dimensional sound experience.
