Engström ARNE Integrated Amplifier (Ex-demo)
Named after a famous Swedish jazz musician and born out of a design process akin to a jazz band mentality, ARNE is a fully balanced 300B integrated stereo-amp. The outward design echoes the heritage of a typical integrated tube amp, but elevates it with our distinctive curves and clean surfaces. Four years of intensive R&D since its 2018 launch has seen it evolve into the ARNE Mk2 in production today. We offer a selection of the best 300B tubes on the market to complement its contemporary circuit design. It is available in a classic all-black or all-white finish, with a choice of clear or smoked glass.
ARNE delivers a staggering 30wpc with grip, speed and dynamics not always associated with common 300B amplifiers. A thick aluminum chassis and adjustable feet (with ceramic balls inside) root the amplifier firmly to the supporting surface.
ARNE uses DC coupling between driver and power tubes. The driver stage has symmetrical positive and negative power supply. The DC level on the output of the driver is then zero, making it possible to connect the driver stages directly to the grids of the power tubes which have individual cathode bias.
This unique way to connect driver stages to the power tubes has big headroom, giving low distortion. The symmetrical DC coupled drive of the power tubes also gives very fast transient response. The sound is powerful, fast and clear.
“We still have a long way to go in our pursuit of completely pure Scandinavian Sound – accessible to all – but I can proudly say that ARNE is the closest we have come.”
Reviews
Hi-Fi Plus, Chris Thomas, 2024
"Regardless of how simple or complex the music is or how it has been recorded this amplifier gives it to you straight and it thrives on both the busy and the spatial. In fact its sense of the whole recording acoustic is one of the best I have ever heard and its ability to conjure up atmosphere often relies on its slightly eerie ways with soundstage depth."
Hi-Fi News, Andrew Everard, 2022
"The evening before listening I’d attended a live jazz gig with a quintet fronted by trumpet and sax, and the immediate impression the ARNE gave was of the same kind of live presence and immediacy, plus that sense of listening to real music. There’s nothing artificial or ‘show your working’ going on here, and neither is there any impression of the stereotypical valve amp traits of the music being warmed over or glossed, nor any slightly noisy background to limit dynamics. Instead, the ARNE just delivers the music, purely and convincingly…"
