Stellar M1200 Mono Amplifier



1200 watt vacuum tube input power amplifier pair



Built in Boulder

The Stellar M1200 monoblock power
amplifier combines the rich warmth and musicality of vacuum tubes with
the jaw-dropping power and seemingly infinite headroom of a 1200 watt
high-performance output stage. This extraordinary hybrid amplifier knows
no limits. From the subtlest musical whisperings to the loudest
crescendos an orchestra or rock band is capable of, Stellar M1200 never
flinches. Regardless of your speaker’s power demands or limitations,
enjoy the once unachievable uncompressed effortlessness afforded by this
design. Pure musical bliss for any loudspeaker made, from the smallest
to the biggest. Stellar.

The M1200 began as the dream project of PS engineer, Darren Myers who
wanted to build a power amplifier without bounds or compression on even
the loudest of musical passages, yet equally at home reproducing the
subtlest of details.


To preserve both uncompressed dynamics as well as the tiniest of
nuanced details requires a cost-no-object input stage, like that of a
high-performance vacuum tube fed from its own analog power supply. The
amp’s delicate input signals, now faithfully preserved by its vacuum
tube input, then need to be amplified without restriction by taking
advantage of a new type of Class D output power module. This
extraordinarily high current, low distortion, MOSFET output stage
combines state-of-the-art topologies with decades of design and
listening experience to produce what we believe is the most musically
satisfying amplifier of its kind.


The over-the-top high power output of the M1200 exists not to match a
small handful of power-hungry speakers, but rather, to act as the
perfect uncompressed power source for even the smallest, most efficient
of speakers on the market.


Remember, power amplifiers deliver only the number of watts required
by your speaker to achieve the desired loudness. Even the most powerful
amplifiers deliver only what’s asked of them. What’s been missing in
most amplifiers is adequate headroom and effortless linear
performance—something only a vacuum tube-based powerhouse like the M1200
can unquestionably provide. From the most subtle of details to unheard
of explosive dynamics, Stellar M1200 represents the pinnacle of high
powered musicality that must be heard to be believed. Regardless of the
power demands—or power limitations—of your loudspeakers, Stellar M1200
is the perfect choice if effortless musicality is in your future.

The Stellar M1200 mono amplifiers solve a classic
problem with nearly every power amplifier made: sonic compression. When
the orchestra gets loud and complex, or the band really starts to rock
it out, most power amplifiers get out of their comfort zone and we hear
their stress and strain as compression. The M1200 was designed to play
any music into any loudspeaker with zero compression. Suddenly, more
than just a sonic veil is lifted when a pair of M1200s are inserted.
Where once music’s character was preserved on only soft to medium loud
passages, with the M1200s in play, there’s no difference between the
softest to the loudest complex passages known. Music is delivered
without prejudice to the recording’s dynamics.

Rated at 600 Watts into 8Ω and a whopping 1200 Watts into
4Ω, the M1200 combines the best of two worlds: ultra-linear,
high-current, ICE Edge Class D technology for the output stage; and a
discrete, Class-A vacuum tube for the all-important input stage. The
M1200’s rich, warm, and beautifully nuanced reproduction of music comes
first from the zero feedback, class A vacuum tube input stage. Here
nothing is lost in its hand-selected 12AU7 vacuum tube, fed from its own
analog power supply.


Our mission with the Stellar M1200 was to produce a
remarkably musical power amplifier without limitations, regardless of
what speakers were paired with it. A common misconception in audio is
that power amplifiers should be matched with loudspeakers by wattage:
smaller sensitive speakers should be paired with small amplifiers and
the opposite for larger, less sensitive speakers. The truth is, for a
given loudness within a room all power amplifiers deliver the same
wattage to match a loudspeaker’s sensitivity. What’s missing in most
systems is a power amplifier with overkill-headroom.  Only then can we
fully appreciate what a massive improvement unfettered dynamics brings
to the system.


The M1200’s designer, PS Audio engineer Darren Myers,
wanted to see what would happen when he combined one of the world’s
highest power amplifier stages with a rich and warm vacuum tube input
stage—the results set us all back on our heels. This hybrid approach
combines the best of today’s technology with time-honored techniques
leveraging PS Audio’s forty-plus years of experience.


The results are extraordinarily musical and dynamic, even
on bookshelf loudspeakers. Never have listeners heard such uncompressed
beauty from small or large speakers. This amplifier has transformed good
to great in ways few among us have imagined possible. After hundreds of
hours of tuning, voicing, and perfectionist tweaking, we were ready to
release this extraordinary combination of power and delicacy to the
world.


One listen to the Stellar M1200 pair and you’ll appreciate Myers’ dedication to musical truth without compromise.

The power amplifier is technology always present in stereo
systems. Yet, despite the fact everyone uses them, few appreciate the
power amp’s critical role in preserving music’s nuanced details because
most amplifiers fail to preserve them. Overtones from plucked
instruments, subtle cues defining placement, depth, soundstage width,
and transient decays are often lost in the power amplifier.


The M1200 loses nothing. Stellar’s lead designer, engineer
Darren Myers, was obsessed with its detail and voicing—lavishing great
attention on even the tiniest nuances in the music. This helped Stellar
capture the rich full-bodied essence of recorded music and presents it
to your loudspeakers with authority and grace—with never a hint of glare
or unnaturalness. The M1200 is faithful to the music like few
amplifiers are.


The vacuum tube makes all the difference


The connection between preamplifier and power amplifier is
critical, for it is at this junction where most essential musical
details and dynamic contrasts are easily lost. Nothing in the design of a
power amplifier is more important than its input stage when preserving
music’s finest nuances. In the M1200 a zero feedback class A vacuum tube
input stage captures every whisper of music while preserving intact the
most dynamic crescendos and quick rise time transients with zero loss.


Long hours of listening and tuning sessions in Music Room
One, shared by PS Audio founder Paul McGowan and Darren Myers, resulted
in a sonic signature that honors the music and never draws attention to
itself.


The listening experience with the M1200 is nothing short
of a revelation. Where most amplifiers do their best to preserve
dynamics, they fail to present them as if they were live. The M1200
eliminates the tendency of nearly every power amplifier to change its
sonic character as the music gets louder. First time listeners to the
M1200 are stunned at the ease and openness of music while expanding and
then maintaining width and depth of the M1200’s soundstage; its
preservation of the smallest details in reverb, room acoustics, musical
overtones; its commanding presence without intrusion; it’s delicate
handling of subtle shadings; its authority as it grabs hold of the
loudspeaker and breezes through even the most complex musical passages.

The hybrid approach used in Stellar’s power amplifiers takes
advantage of the best traits technology has to offer. Its all important
input stage relies upon its 12AU7 vacuum tube to provide a zero-loss
interface between the preamplifier or DAC, as well as imprint the amp’s
sonic character. It is then time to convert the perfected analog voltage
into the all important high current output needed to drive
loudspeakers.


A power amplifier connects a reservoir of energy to the
loudspeaker through a type of valve (solid-state or vacuum tube)
controlled by the input stage. If the input stage has done a good job of
preserving music’s subtle details, textures, timing and phase
information, transferring it without loss to the loudspeaker can be
accomplished in a few ways: the most efficient is Class D.


The history of Class D amplifiers stretches back to the
1950s, though those early designs—even those into the late 1990s—had
much to be desired, sonically. Modern designs capable of high linearity
and neutral sound quality weren’t available until the early 2000s, and
into late 2015.


There is a lot of misinformation surrounding class D
amplifiers. Perhaps the most common is they are digital, which is
incorrect. A Class D amplification stage is an analog process, known as
Pulse Width Modulation (PWM). Class D amplifiers do switch in on/off
fashion, which is likely the reason they wrongly acquired the “digital”
moniker.


The Stellar M1200 has a massive power factor corrected
power supply and ultra-linear high Wattage power amplification stage,
based on the newest ICE Edge technology, designed in Denmark.


The Stellar M1200 provides excellent frequency extremes,
low distortion, high efficiency, high damping factor, and a generous and
powerful output of 1200 Watts into the most common loudspeaker loads of
4Ω.


Is 1200 Watts too much for my loudspeakers?


No. As mentioned, power amplifiers need not be matched to
speakers for fear of overpowering them. Their output wattage is
controlled entirely by the preamplifier and user’s volume setting. The
advantages of a massively powerful amplifier like the M1200 are headroom
and increased linearity for any input signal of any size. The end
results are nothing short of breathtaking Regardless of what
loudspeakers, the massively powerful nature of the M1200 works well with
any loudspeaker, providing huge amounts of headroom and effortless
sound quality for even the most demanding orchestral crescendos.
