Air Tight Opus-1 Ermitage cartridge, released in honour of AirTight’s 30th anniversary is in the very top echelon of MC phono cartridges in the world and offers a performance that has to be heard to be believed. It is the result of many years of development and collaboration between the most renowned Japanese cartridge designers.

It incorporates a unique (exclusive to the Opus-1) ultimate performance SH-uX core sealed in an ultra-hard duralumin housing which is then fortified by nickel plating. It aims at delivering the optimum combination ratio of internal impedance and output voltage. This technology gives the Opus-1 the ability to reproduce slight changes in signal intensity as a continuum and differentiate between subtle shades with ease.

The Mono version brings this technology to the audiophile who wants to apply it’s wonders to mono recordings. Drop it into a groove and the Opus-1 Mono opens a world of palpable three-dimensional imaging, a wide and deep soundstage and a sense of realism reminiscent of a live event. Such is its sublime sonic picture that the listener is drawn into the music with a deep emotional engagement and sense of believably. For audiophiles who are searching for the ultimate performing mono cartridge to add to their analogue system, the AirTight Opus-1 Mono must be on their short list. Rare and uncompromisingly brilliant
