The M3si offers increased power, more inputs, and a new dual-mono circuit layout which reduces the noise floor and greatly increases dynamics. The M3si is a true high-end amplifier with sound quality that belies its price. Because its power output has increased significantly, the M3si delivers a wide, stable and deep stereo image with a more realistic portrayal of instruments and voices. More than that, the M3si offers a sweet, rich, and natural level of musicality that sounds effortless with tremendous clarity. The new circuit design delivers much more controlled bottom-end and unmatched transient speed. The bottom-line is that Musical Fidelity has just created the amplifier to beat at this price. The M3si offers high quality sound with an extensive range of useful inputs in a compact package with reliability and a fair price. The M3si uses Musical Fidelity's exclusive SMD layout techniques. This reduces the circuit's footprint on the large PCB and greatly increased flexibility with the layout and the ability to add more inputs and, importantly, power amp PSU capacitance. The M3si delivers 76 watts per channel. Distortion at 1 kHz is very low at 0.007%. Even at 10 kHz it is hovering around 0.01%. The M3si's very low HF distortion proves that the layout circuit and circuit design are operating in perfect harmony so that there is low distortion at HF. Signal/noise ratio has been improved by more than 3dB. This is a significant step which allows more music to be heard with a greater dynamic range. Channel separation is excellent. The MM phono stage has very accurate RIAA equalizati ProductSiteLaunchDate : 2015-07-31T01:41:49.903Z Size : ZK-502L (50W+50W) SpecificationMet : CE SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredHasProductIdentifierExemption : 1 SupportedStandards : MP3 SurroundSoundChannelConfiguration : 2 TunerTechnology1 : FM TunerTechnology2 : Auxiliary UnspscCode : 52161547 Voltage : 5 volts WarrantyDescription : 1 Year Manufacture
