Master Amplification – A New Era

Transforming the full range of music from dignified silence to surging passion, a new milestone in amplifiers brings together wisdom and technology. Esoteric’s Grandioso M1 “X” Edition.

Dynamic Soundscape
As the music starts to play, the presence of the audio component disappears into the background and the excitement of the listening experience is revealed; a place where the music is unleashed in all its dynamism and majestic scale. By introducing an inordinate number of new materials, particularly the completely redesigned drive stage and power supply section, the M1X’s New signature sound provides music with an extra dimension.

Ultimate Fidelity
Esoteric, as a high-end brand, has been at the forefront of audio innovation. Along with the Grandioso C1X linestage preamp, Esoteric challenges the limits of fidelity in preamp to amplifier signal transmission. Esoteric's unique current transmission system “ES-Link Analog” is the ideal method for preamp to amplifier transmission where the signal level is extremely low. Compared to the conventional voltage transmission, it transmits approximately 100 times more current, making it less susceptible to noise and sending the full energy of the music to the amplifier.
Also, in principle, it is not affected by the impedance of the interconnects running between the preamp and amplifier, so it is possible to maintain perfect integrity between the output signal of the preamp and the input signal to the amplifier.

2,400W/1Ω
The all-new drive stage has been expanded in size by 150%, from 6 to 12 parallels, while boasting an astonishing power linearity from 300W/8Ω to 2,400W/1Ω*. It delivers sufficient current in a perfect correspondence with the change of load level, effectively meaning you won’t need to concern yourself over what speakers you can use. Now, you can enjoy the true sound of the original master, even on music with a wide dynamic range.
*Only for music signals.

Infinite Power
Everything about the M1X is done on an extraordinary scale. The M1X’s incredible power is supported by Esoteric’s largest-ever power supply, which occupies the space of approximately 60% of the unit’s internal components. The 3,000VA/19kg main power transformer has been further refined in terms of rectification capability by implementing heavier winding gauge. In addition, high-capacity Esoteric custom capacitors with a total capacity of 60,000μF have been adopted to refine the amplifier’s signature high-quality tone.

Resolution
Even at the climax of a full orchestra, the M1X will draw forward even the most nuanced detail from every instrument with its key feature high resolution capability. Incorporating a dedicated power supply unit for the pre-drive stage (voltage amplification stage) that handles extremely low-level signals from the preamp, the M1X eliminates the influence of the drive stage with its large current fluctuations and improves resolution.

Simplicity Is Excellence
Considering its massive appearance, you may be interested to learn that the circuitry of the M1X is surprisingly simple. The crystal-clean sonic signature of the M1X is composed of a product of advanced engineering known as, “Aesthetics of subtraction”.

Harmonics
For example, all 24 transistors on the drive stage are controlled to be the same temperature for total balance and stability, and the phase compensation circuit employs a simple single-pole configuration, which also allows the final stage to be coil-less. With its minimalist circuitry philosophy, it maintains the harmonics (overtones) that are most important to music, but are often easily lost, and draws them out with rich expression.

Into the Deep End
While the M1X’s circuitry is minimalist, the components are among the largest. Its extra thick copper clad printed circuit boards, the huge bus bars used in the drive stage, and the ultra-heavy gauge cables with secure, lossless bolt on connector system, are reminiscent of a huge aircraft engine. By reducing the internal impedance and by gripping even a large diameter woofer with authority, its driving force reaches the limit of the low frequency range with ease.

Sonic Gradation
The M1X not only delivers the dynamism of high power, but also renders the gradation between climax and silence with amazing subtlety. A newly designed balanced input stage amplifier that is independently settled on each input, receives the signal and transmits it to the amplification stage in a balanced configuration to ensure noiselessness. Carefully selected components such as IDM-01 (Integrated Discrete-Amplifier Module) originally developed for the C1X preamp, and FET switches used in input selector, further enhances the micro detail of the music.

Mechanical Perfection
The M1X’s chassis optimally controls any vibrations that may affect the sound quality to achieve the absolute design goal of “Master Sound Reproduction”. Like a Formula One race car, its sleek and clean appearance with mechanical engineering that pushes the limits of the balance between rigidity and flexibility, is a testament to its high level of perfection.

Dual Honeycomb Grille
The most eye-catching feature of the M1X exterior, the top panel's "Dual Honeycomb Grille" symbolizes the evolution from the preceding M1 to the M1X. The honeycomb-shaped opening was adopted to maximize the efficiency of the internal heat exchange and to reduce the top panel weight as much as possible to enhance sound openness. By stacking two grills of different thicknesses with offset hole-positioning, vibrations are also dispersed efficiently in pursuit of a pure tone.

Rigidity / Flexibility
To ensure resonance-free operation, the M1X employs the extensive use of aluminum blocks on the body enclosures. For example, the front panel is machined from a 35mm-thick aluminum block, while the top panel, on the other hand, which needs to be free of vibration for an open sound, has a semi-floating structure, and the isolated feet have their own special structure that reduces mechanical stress and enhances sound quality.

Great speakers For my needs. Wanted a nice full sound floor standing speaker that wasn’t harsh. Using them just for music in our fireplace room not for home theater. Not a complaint at all on their lack of lower end frequencies, I pretty much knew when I ordered them I’d be adding a sub to the mix to fill in where they leave off. Now to pick the sub 😅😂

Fast shipping and products arrived perfectly. Thank you for a good experience

The delivery was quick and the unit arrived earlier Then expected because I live on the west coast.
The Eversolo T8 is everything as advertised and reviewed. The unit took about 8 hours of use to lose the bright forward sound. I’m happy with my purchase from Sate and Sound.

I'm glad I made the choice to purchase this amplifier! I couldn't be happier and the sound is quite captivating.

I just came back from visiting my big brother out of state who has a system in the mid 5 figure mark. When I came back I was inspired to upgrade but decided to wait. But then my Sub stopped working. I saw these on sale and thought “Is it meant to be?” Of course it was. I have these paired with a NAD T-778 streaming Qobuz. So far I am really enjoying these. I am hearing old songs as if they are new again. I have been listening to music more than ever. Bass is solid and highs are crisp. A truly immersive speaker. While I wouldn’t dare say they are as good as my big brother’s setup, they are close enough to put a smile on my face. I think they are a solid option for the price range. I am very satisfied and they are still breaking in.

Absolute game changer! Love the device - terrific sound quality, intuitive interface and beautiful design!

My amplifier arrived safely and has functioned wonderfully without issue. Thank you!

Reference caliber exotic retro-futuristic LP spinner. Few rivals. Few are so flexible.

I started years ago with an Ortofon Blue and this directly replaced a Mofi Mastertracker. I have coupled the LVB250 with a Darlington MB8 phono preamp and I can finally say that I am satisfied. This cartridge is exceptional and I don't think I'll ever need anything better.

Really good service and extremely fast shipping. Also good price on receiver.

Love the power of it it really feels like the gate way into high end it sounds beautiful happy with your service.Everything was all I hoped it would be thank you

I bought the M2si integrated amplifier to drive my 2.7 magnepans. It does a very nice job of doing just that. That the amplifier is advertised as dipping gracefully or smoothly down to 2 Ohms was a primary point in the buy. Plus, Safe and Sound had a very good buy on this amplifier at $ 799.00. The build quality is very good and it has a large toroidal transformer to better handle high current and increase bass response. The preamp is full Class A and is a strong point for this Class A/B amplifier. Great buy! You can't have it all at this price though. The motorized volume knob does not have an easy viewing of where it is set as it is an inset indention without a light marker. Also, no standby power for the amp but it does have excellent heat management as the chassis has a colder side versus the hotter 2 channel amplifiers side. It is a fully discrete amplifier (wonderful, no integrated except for maybe op-amps at the preamp front). 5 year warranty, hard to beat. The amplifier has to be broken in as treble is at first very forward , but settles after a good break in period. The silver white looks very sexy and has a kind of older vibe. The M2si is British and has a brightness to it which can be toned down if you use the right speakers. Magnepans can change resistor values at the terminals or maybe even use specific DACs. No complaint about not having digital inputs at all since there are plenty of line level inputs as you can use outboards which gives you more opportunities any way. I have three different DACs into the line level inputs so all I have to do is switch out the single coax cable I want to change some of the response. I like a very well made Class A/B like this unit compared to the Class D which I have tried. Soundstage is wide and there is a lot of headroom compared to a lot of class D. If the M2si performs at 90% of what their end does like it has been said, then wow. Way to go Musical Fidelity.

I have all Arcam equipment, the sound is fantastic. The price was amazing.. MusicLife app is so/so. Great piece of equipment..

Safe and Sound is an excellent place to buy audio gear. This phono preamp is excellent, as sounds as advertised and the price was right!

Amazing to deal with and best service on the planet

So pleased with the quality as well as pretty much next day delivery. Great company

Excellent CD player. Very impressed with the quality of the open box service. Absolutely impeccable, couldn’t tell from a brand new unit. Your customer service is also tops. Thanks for great shopping experience!

Amazing sound. Perfectly pairs with the components I have. Vinyl has never sounded better.

Unit sounds great butyou can hear sound bleeding through the speakers and amp at zero volume. Also bind post so small myspade pugs either too large to accommodate. Unit turned off several times, not sure why possible connection but I could not figure out maybe due to heavy load speakers .Ssrvice and sales always fantastic!

Super quick shipment and communications! Always great experience with Safe and Sound! The T8 is amazing! Big improvement over DMP 6!

These outperform my previous speakers by a wide margin: more punch, more body, higher articulation. The vocals are mesmerizing.

I was trying to scale down from a surround to a stereo setup and looking to upgrade DAC from Marantz av8805a. I have the Anthem mca 525 gen 2 amps and Sonus Faber Sonetto iii g2. It took about 70+ to burn in. It was an upgrade, but it is very subtle and hard to even notice unless really paying attention. This does fell like within the territory of diminishing returns. I don't know if it's because of my speakers, but it is the best speaker I can get given the size and weight for a small walkup apartment. However, I still decided to keep it because it is much lighter and runs cooler than the Marantz. It is also a little bit clearer (the Marantz sounded a little bit muddied, which I didn't even notice after years of using until I was comparing it with m3ai) and I noticed that it sounded louder at the same db level because of this (this means I can listen at lower db levels than I would with Marantz). I do miss the ability to fully control the Marantz via the android app. Overall a good DAC, but subtracting a little bit of points for the high price.
