Manley Studio 440 and 240 Monoblock Amplifiers

Features And Specifications | Manufacturer's Suggested Retail Price

We believe the monitoring system (speakers, amplifiers, and room) is the most important equipment in any recording or mastering room. This is the lens through which you inspect all your work and make all your decisions. It is the first thing a new client hears when deciding whether your room is the room. Then there is the question of aural fatigue brought about by inferior amplifiers running at a too-high level that engineers and producers have to deal with into the wee hours. And later (in the accounting department) the cost of replacing drivers constantly being blown by poor solid-state amplifiers clipping into square wave. . . The answer, unequivocally, is high power with lots of headroom, low distortion, VACUUM TUBE amplifiers. Manley Labs has a world-wide reputation for high-end amplifiers in the audiophile market; we make scads of ‘em, actually, from 15 watts of single-ended insanity up to 500 watt brutes.
