What customers say
The Legacy Audio iV4 Ultra is celebrated as a reference loudspeaker for its breathtaking sonic performance. Owners consistently praise the expansive, three-dimensional soundstage and remarkable clarity throughout the frequency range. High frequencies delivered by the AMT tweeters are pristine and nonfatiguing, while integrated subwoofers provide exceptionally deep and controlled bass. The listening experience is often described as effortless dynamics and uncolored neutrality. The primary friction points involve the significant financial investment and the complexity of the Wavelet II DSP setup, which can require professional calibration. Despite these barriers, owners agree the performance justifies the cost, establishing it as an endgame product for serious listeners.
Know before you buy
With 610 watts per channel into 8 ohms and high current stability, this amplifier is designed to drive demanding, high-end speakers that require significant power to reach their full potential. It is particularly effective for large floor-standing speakers or complex multi-channel home theater setups that need consistent, clean power across all channels.
The i·V4 Ultra utilizes advanced ICEedge® technology, which bridges the gap between the efficiency of Class D and the sonic purity of traditional designs. You can expect a highly detailed, expansive soundstage with virtually no background noise, making it a competitive choice for critical listening.
Yes, the i·V4 Ultra is equipped with both balanced XLR and single-ended RCA inputs. This versatility allows you to integrate it into a wide variety of audio systems, whether you are using professional-grade balanced gear or standard consumer components.
Because it operates at approximately 80% efficiency, the i·V4 Ultra runs significantly cooler than many traditional Class A or Class AB amplifiers. This thermal efficiency not only helps the unit stay reliable over time but also makes it easier to place in enclosed cabinets or racks.
The amplifier includes comprehensive protection systems, specifically designed to guard against short circuits and thermal overload. These systems monitor the unit's performance in real-time, ensuring that your speakers and the amplifier itself remain safe during high-output operation.
The front panel status indicator provides a quick, visual confirmation of the unit's power state and operational health. It is a practical feature that allows you to verify at a glance that the amplifier is active and functioning correctly without needing to check the rear connections.
