Exceptional amp from Magnus Audio
From Terry London's review:
"The MA-400 has tube-like sonic qualities, such as richer and more natural colors/tonality/timbres, three-dimensional imaging, and a grainless liquidity not often found in solid-state amplifiers. However, this does not come at the expense of transparency and micro-details or a lack of dynamics and lower-frequency extension or control. I believe that--based on performance, quality of parts, and the high level of construction - the Magnus Audio MA-400 stereo amplifier belongs in the higher echelon of solid-state equipment on today's market."
MA-400 HighlightsAdvance and sophisticated Class AB design with high output performance. 24 carefully selected and matched MOSFET output transistors of highest quality. Current mirror input for more stable output throughout entire dynamic range Custom wound audio grade toroidal transformer with separate windings for
left and right channel. Custom made heavy-duty heat sinks with special thick rib design ensure a lower operating temperature. Sophisticated protective circuit ensures highest operational safety for the amplifier and the connected loudspeakers. Integrated power circuit with time-delay relay to eliminate turn-on thump. Advance layout and wiring techniques guarantee a hum free operation. Switchable balanced (XLR) and single-ended (RCA) inputs. Full metal housing for optimum shielding. Handcrafted in California, USA.
