NORMA REVO IPA-140

Pre owned. In excellent condition. Shows no significant signs of wear. Comes with remote control; does not include original packaging.

The Norma Revo IPA-140 represents the pinnacle of Italian hi-end amplification, combining power, precision, and musicality in a single integrated amplifier designed for the most discerning audiophiles. With 140 watts per channel into 8 ohms and 280 watts into 4 ohms, the IPA-140 dominates every listening scenario, from intimate jazz to full orchestral soundtracks, thanks to its dual mono architecture featuring two 400 VA toroidal transformers and 72,000 µF of filtering distributed across 24 low-impedance capacitors, ensuring maximum linearity and dynamic response. The high-current MOS-FET devices, twelve in total, deliver up to 150 A peak, handling even the most demanding speakers with authority.

The ultra-wideband phono stage, built on two separate monophonic boards for each channel, supports MM and MC cartridges with ultra-low noise and response beyond 2 MHz, while the optional USB DAC board at 24-bit/192 kHz allows seamless integration of digital sources. The amplifier offers five analog inputs in total (four RCA and one balanced XLR), optional phono inputs, and configurable outputs including Pre Out, Active/Passive, and Subwoofer Out, making the IPA-140 a flexible hub for complex systems, while the Direct AV mode bypasses the preamplifier for home theater applications.

The construction of the IPA-140 is meticulously crafted: the non-magnetic aluminum chassis, four-layer printed circuit boards, and silent transformers with high-permeability cores ensure pure, interference-free sound extraction. Relay contacts are made of gold/palladium, RCA connectors are solid-core gold-plated, and the aluminum RC-4 remote with two-speed volume control provides full system management. The design includes DC protection circuits to safeguard sensitive speakers and a standby mode that powers down the microprocessor, eliminating any interference with the analog signal.

Listening to the IPA-140 transcends mere music playback: the bass is deep and layered with surgical control, the midrange is natural and dense, capturing the breath of a voice or the texture of a violin, and the highs are fluid and free of sibilance even at high volumes. The three-dimensional, enveloping soundstage allows instruments to be perceived spatially in an almost tactile way, turning every track into an emotional and immersive experience. Every element of the Revo IPA-140, from its high-speed, low-noise topology and separate Gain, Driver, and Output power supplies to the possibility of integrating high-quality phono and DAC boards, is designed to provide an absolute reference in musical reproduction and a lasting investment for those seeking sonic excellence.

With uncompromising power, transparency, dynamic range, and flexibility, the Norma Revo IPA-140 stands as a masterpiece of Italian engineering, combining cutting-edge technology, artisanal craftsmanship, and an emotionally engaging sound, destined to become the beating heart of any hi-end system.
