M1200 Amplifier

The Stellar M1200 mono amplifiers are a high power super linear amplifier with a vacuum tube input providing uncompressed performance.

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.

DESIGN

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. 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.

APPLICATION

Power amplifiers delivers 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.

Technology

OVERVIEW

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. 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.

THE VACUUM TUBE INPUT

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 because of its vacuum tube input stage. 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. 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.

OUTPUT STAGE

The Stellar M1200 has a massive power supply and ultra-linear, high-wattage power amplification stage based on a modern Class D ICE module. Class D output stages provide near-perfect linearity, low distortion, and high efficiency. Modern Class D amplifiers, like the type used in Stellar, extend high frequencies to about 50kHz. Human hearing limitations are 20kHz, though most listeners rarely have hearing exceeding half that. Providing 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, the M1200 is nothing short of breathtaking. The massively powerful nature of the M1200 works well with any loudspeaker—big or small—providing huge amounts of headroom and effortless sound quality for even the most demanding orchestral crescendos.

Reviews

 

As it happened, however, my system was in flux, with gear whizzing in and out the door; so, I put the M1200s first on the WAMM main loudspeakers without harboring too great expectations. Boy, was I in for a surprise! The M1200 is not a good amplifier; it is a superb one.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.

Stunning Gentleman's Watch
Color: Grey
This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.
