THIS PIECE DOES IT ALL!

M6si - Overview

The new M6si integrated amplifier improves on the outgoing
M6i model with more inputs and completely new internals to give greatly
improved technical and sonic performance

The M6si has real high-end sound quality. Because of its
power it is effortless and unstressed. Its stability margins are huge so it
will drive any loudspeaker easily. These are only the bedrock for what the M6si
really does: sounding fantastically musical. Because of its pre amp/power amp
configuration it produces wide stable images with an effortless, clear,
ungrainy sound quality. Bottom end is delivered with a vast punch and speed of
attack.

All in all the M6si offers true high-end sound quality, an
extensive range of useful inputs, a compact package, reliability and a fair
price.

M6si - Design and Build

We felt that the original M6i’s package size, power and
price were spot on.  What was needed was
the addition of extra input facilities and, if possible, an all round
improvement of technical performance.  By
the way, despite endless component price rises during the M6i’s life, we didn’t
alter its selling price.  This made our
final requirement even harder; the M6si should not be significantly more
expensive than the outgoing model.

First we determined to use Musical Fidelity’s exclusive SMD
layout techniques.  This reduced the size
of the circuit’s footprint and gave us greatly increased flexibility with
internal layout.  Consequently the new
M6si is configured as a pre amp with two completely separate and independent
monobloc power amps.  The M6si is a
proper pre amp with its own separate regulated power supply and discrete
monobloc power amps, sharing same casework. 
This is a big change from the outgoing M6i.  The M6si’s technical performance is a
significant advance on the old model.

Performance

 The M6si performs immaculately.  Because of its pre amp with two monobloc
power amp configuration both channels perform virtually identically, just what
you would expect from a pre amp with separate power amps and not what you would
expect from a normal integrated amplifier. 
The M6si is a cut above everything else.

Distortion is very low at less than 0.005%.  More tellingly, HF distortion is incredibly
low.  At 10 kHz about 0.006% and at 20
kHz an astonishing 0.007%.

The vast majority of amplifiers suffer huge increases in
distortion as you go up in frequency.  The
M6si’s meticulous PCB and circuit design means that HF performance is virtually
identical to the LF performance.  This is
significant for sound quality.

Channel separation is remarkable, and remarkably
consistent.  Most amplifiers (integrated
or pre/power) have dramatically worsening cross talk with increasing
frequency.  The M6si cross talk is
outstanding and even at 20 kHz it is better than 82dB.

The phono stage is also special.  It has very accurate RIAA, within ± 0.5dB
from 20 Hz to 20 kHz.  Also it maintains
its accuracy right out to 50 kHz.  The MM
noise ratio is an outstanding 93dB down whilst the MC stage is, perhaps even
more amazingly, about 87dB down.  The
phono stage distortion is a very low 0.01%. 
All in all the M6si’s phono stage is exceptional.

USB Input

The 24 bit 96 kHz asynchronous USB input uses exactly the
same circuitry and technology as our highly regarded V-Links and other top
quality computer interfaces.  Jitter is
virtually eliminated.   Noise is incredibly
low and distortion virtually non-existent. The M6si’s USB input is capable of
dredging the finest details from the computer source.
