Musical Fidelity M3si Integrated Amplifier (Silver)

In Stock	An In Stock item is available to ship normally within 24 business hours.
Preorder	A Preorder is an item that has not yet been released. Typically the label will set a projected release date (that is subject to change). If a projected release date is known, we will include this in the description in red. Other Preorders are set to release 'TBA.' This means that release date is yet 'To Be Announced'. The Preorder can be released anywhere between weeks, months or years from its initial announcement.
Backordered	An Out Of Stock item is an item that we normally have available to ship but we are temporarily out of. We do not have a specific date when it will be coming.
Awaiting Repress	Awaiting repress titles are in the process of being repressed by the label. No ETA is available at this time.
Expected On	When an item is Out Of Stock and we have an estimated date when our stock should arrive, we list that date on our website in the part's description. It is not guaranteed.
Special Order	A Special Order item is an item that we do not stock but can order from the manufacturer. Typical order times are located within the product description.

The M3si offers high quality sound with an extensive range of useful inputs in a compact package with reliability and a fair price!

Overview:
The M3si integrated amplifier makes huge strides from the outgoing M3i model. More inputs, increased power and virtual monobloc power amps with their own separate power supply capacitance add up to a great new product.

The M3si offers a real taste high-end sound quality. Because its power has increased significantly and it now has more than double the capacitance, it gives wide, stable and deep stereo images with a substantial dynamic range. More than that, the M3si offers a sweet musical sound with an effortless, clear, ungrainy quality. Because of the virtual mono power amp configuration with increased capacitance, the bottom end is delivered with punch and excellent speed of attack.

The M3si offers high quality sound with an extensive range of useful inputs in a compact package with reliability and a fair price.

Design and Build:
The M3si uses Musical Fidelitys exclusive SMD layout techniques. This reduced the circuits footprint on the large PCB and gave Musical Fidelity greatly increased flexibility with the layout and the ability to add more inputs and, importantly, power amp power supply capacitance. Now there is a pair of big power supply capacitors for each channel. Power is a generous 90 wpc.

The new M3si now delivers a healthy 90 wpc. Distortion at 1 kHz is very low at 0.007%. Even at 10 kHz it is hovering around 0.01%. Most hi-fi amplifiers have a huge increase of distortion with rising frequency. To us this shows that the whole circuit design/layout concept is not good enough. The M3sis 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. We believe this validates the performance and integrity of the whole design.

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 is high performance. It has very accurate RIAA equalisation, within ± 0.5dB from 20 Hz to 20 kHz. The accuracy is maintained out to 50 kHz. Noise ratio is an outstanding 88dB down. Distortion is less than 0.3%. The M3sis phono stage offers potential of great MM performance.

The 24 bit 96 kHz asynchronous USB input uses exactly the same circuitry and technology as their highly regarded V-Links and other top quality computer interfaces. Jitter is virtually eliminated. Noise is incredibly low and distortion virtually non-existent. The M3sis USB input is capable of dredging the finest details from the computer source.
