Musical Fidelity M6SI500 INTEGRATED AMPLIFIER
- Free Shipping
The M6si500 is a very high performance, high powered super integrated amplifier. Twenty-five years ago, the Musical Fidelity A1000 started the complete super integrated amplifier genre. Over the last two and half decades we have continued to refine our original concept.
The M6si500 offers a comfortable 500 watts per channel, incredible load driving ability, outstanding technical performance and solidly engineered build quality. This remarkable integrated amp will drive any loudspeaker virtually perfectly and to its maximum potential.
It has five inputs: 4 x line and 1 x balanced XLR.
Listening to the M6si500 is a sensuous experience. It produces an effortless, silky sound with huge dynamics. The sound stage is broad and deep. Even if you aren’t in the market for an amplifier at this level, you should listen to it to better understand why it is generating such enthusiasm.
M6si500 In Brief
- Fantastic technical performance
- Amazing load driving ability, will drive any loudspeaker with ease
- Five inputs – Balanced XLR, CD, Tuner, Aux / HT, Tape
- Preamp and fixed line outputs
- Home Theatre bypass
- Internally it is a separate preamp with two independent monobloc power amps; effectively a separates system in a box
- Excellent, he-man build quality
The M6si500 offers prodigious power – 500 Watts per channel into 8ohms – but there’s so much more to it than muscle.
The M6si500 has a high-quality metal build that gives it both distinctive style and a solid performance platform. The front panel is a bespoke, fine-line extrusion of military-grade aluminium, while the heatsinks are also custom-made for outstanding dissipation plus a fine finish.
We have engineered the M6si500 as a genuine dual-mono design. Each power amp section has its own heat sink and separate transformer, while the preamp has its own power-supply winding.
The five input sockets are connected directly to the main preamp circuit board, instead of using wire connections. This ultra-short signal path ensures ultra-low impedance from the instant sources feed into the M6si500.
Meanwhile, each channel has 12 big bipolar transistors; 200 amps peak-to-peak performance is readily available.
In addition, a precision digital volume control – using laser-trimmed substrate resistors – ensures perfect tracking right down to very low listening levels.
Such attention to detail delivers stellar technical performance. For example, distortion levels are remarkably low – around 0.008% at 1kHz and 0.015% at 20kHz, and only marginally rising to 0.02% at ultra-high frequencies of 30-50kHz. Signal-to-noise ratio is also minimal.
The M6si500 has remarkable linearity and consistency, enabling it to drive any speaker with ample power reserve. It sounds effortless, fluid and dynamic: the way the very best amplifiers should.
