NORMA REVO IPA-140

Pre owned. In excellent condition. Free from visible signs of wear. Supplied with remote control and manual, original packaging not included.

The Norma REVO IPA-140 integrated amplifier stands as a reference-class component in the high-fidelity audio world, designed to deliver absolute-level sonic performance and built for long-term reliability. Its dual-mono architecture and meticulous circuit design make it a true cornerstone around which a high-quality audio system can be built, capable of driving and enhancing any type of loudspeaker regardless of technology, sensitivity, or load requirements.

Its sonic character is defined by authority, refinement, and a remarkable absence of limitations, achieved through an extremely fast and ultra-quiet circuit topology with a wide bandwidth exceeding 2 MHz and a design philosophy focused on maximum signal transparency. The power stage employs high-current MOS-FET devices capable of delivering peak currents up to 150 A, while the overall structure integrates twelve power devices for a total power handling capability of up to 1500 W, ensuring excellent control even with complex and demanding loudspeakers.

The power supply is one of the key elements of the design, featuring a fully separated architecture for gain, driver, and output stages, with fast, low-noise regulation for the most sensitive sections. The filtering capacity is particularly substantial, with a total reserve of 70,000 µF distributed across multiple low-impedance capacitors, while the custom-designed audio-grade toroidal transformers ensure low magnetic leakage, reduced mechanical noise, and low output impedance.

Operational flexibility is provided by five user-configurable analog inputs, allowing easy adaptation to different audio systems and sources. A dedicated direct AV input is included for home theater integration, while the outputs can be configured as pre-out, active, or passive, offering maximum versatility when connecting power amplifiers or active subwoofers. A balanced XLR input completes the connectivity package for professional-grade, interference-free signal transmission.

Special attention is given to the phono stage, available in MM/MC configuration and designed with a fully dual-mono architecture, with completely separate signal paths for each channel. This approach ensures maximum analog purity and outstanding precision in vinyl reproduction. An internal high-resolution USB-DAC board (up to 192 kHz / 24-bit) can also be optionally installed, further expanding the unit’s functionality.

Volume control is handled via a dual-speed system, offering both fine and fast adjustments for precise and immediate operation, while input selection is managed through relays with gold and palladium contacts, ensuring long-term reliability and optimal signal integrity. All signal connections use solid-core gold-plated RCA connectors, and the entire chassis is built from non-magnetic aluminum to minimize interference.

To complete the design, the system includes protection circuitry for DC-sensitive loudspeakers and an intelligent standby mode that fully shuts down the microprocessor after execution of commands, further reducing potential interference in the analog signal path. Full remote control of all functions is provided via the dedicated proprietary remote, ensuring convenience without compromising audio purity.
