Esoteric Grandioso F1 - Integrated Amplifiers - Audio Impact (2022)

The Grandioso F1 is a fully balanced preamplifier that descends from the Grandioso C1. It is resilient to noise, and can amplify signals purely and powerfully with low impedance.

Dual Monaural Configuration

A dual monaural configuration with separate left and right sides has been adopted for all stages; from the preamplifier stage to the final stage of the power amplifier. The inclusion of the largest amount of materials ever used in the circuits of an all-in-one Esoteric amplifier ensures both superior sound quality and channel separation.

"ES-LINK Analog" Method for High Quality Current Transmission

In addition to regular line connections (XLR and RCA), the Grandioso F1 features the new "ES-LINK Analog" transmission method developed by Esoteric. This current transmission method utilizes the high performance of the HCLD buffer circuit and its enhanced ability to supply power at high-speed to transmit a pure and strong signal with minimal interference from the impedance of the signal route. This is the ideal method for analog audio transmission as it fully maximizes the system's potential when connected to a compatible device.*

*Included in the Grandioso K1 as of September 2016. A standard balance cable (with an XLR terminal) is used for connections, but the "ES-LINK Analog" method can only be used with compatible devices since it is a proprietary transmission method.

ESOTERIC-QVCS

The F1's Esoteric-QVCS* volume control employs four precision switched resistor ladder networks, which change in unison as the volume knob is rotated. This arrangement allows the signal paths for the left and right channels and their positive and negative phases to be kept totally independent and as short as possible. Consequently the sound has superb clarity, excellent channel separation and highly accurate phase characteristics. The elimination of audio board wiring to the volume control further contributes to a reduced signal path, while preventing degradation of sound quality and helping to maintain the low distortion one would expect of a reference model.

*QVCS = Quad Volume Control System

Ultra Low Noise Logic Controls

All control systems in the Grandioso F1 are electrically separated from the main preamplifier using isolator chipsets and contained in the front panel to effectively minimize noise.

High Precision Ball Bearing Control Knobs

Employing the same high-precision bearing system used in our VRDS transport mechanisms, the F1's volume control knob and selector switch provide exceptionally smooth operation with an analog feel free of any mechanical play. Sparing no cost, the front panel and all panel knobs are custom-machined from solid aluminum.

Dual Mono Phonostage Preamp

The dual mono phonostage preamp (MM/MC) features independent left and right channel power sources and independent circuits.

High-Quality Headphone Amplifier

The powerful headphone amp provides abundant output to effectively drive even difficult to power high-end high-impedance headphones.

3-Band Tone Control (Treble/Middle/Bass)

Commitment to achieving all the quality associated with high-end components results in a balanced dual monaural configuration consisting of four circuits (L/R, -/+) for each band. This system enables users to adjust tone settings free of any concerns about sound quality deterioration. Shifting the variable band more than usual toward the high and low frequency ranges (14kHz/63Hz) permits fine adjustment of bass and treble without adversely affecting the original source signal. Fully electronic control also permits fine adjustment of up to ±12dB in 0.5dB steps.

"ESOTERIC MODEL200" Next-Generation Silicon Carbide MOSFET

Each year it is becoming harder to obtain discrete parts with excellent audio quality. That is why Esoteric, which prides itself on in-house production, decided to collaborate with New Japan Radio Co., Ltd. to develop a proprietary MOSFET device that meets stringent sound quality and performance standards. After more than two years in development, we finally completed our first proprietary MOSFET for the Esoteric brand, called the ESOTERIC MODEL200.

The ESOTERIC MODEL200 is a dedicated MOSFET device for the power amplifier output stage that uses a next generation power device and the widely lauded high-tech material called silicon carbide (SiC). Since it features lower capacity and lower loss than regular silicon devices, its current tolerance performs amazingly well in benchmarks, with a maximum instant current of 150 A and continuous current of 78 A. Since it can freely control a large current with quick startup, it is excellent for driving low-frequency ranges and provides powerful playback of music. Furthermore, its greatly improved transient response provides extremely low noise with high-frequency ranges for lively and vibrant sound throughout the entire audio spectrum. This is the ideal MOSFET device for a flagship model, due to its ability to powerfully, flexibly and naturally follow the dynamics of ever-changing music.

Parallel Push-Pull, Class A, 30W+30W(8Ω)

The Grandioso F1 adopts a newly-designed parallel push-pull Class A power amplifier circuit to bring out the most of the ESOTERIC MODEL200 silicon carbide MOSFET. This faithfully adheres to the Esoteric amplifier philosophy of using impressive quantities of the finest materials while adopting a minimal circuit configuration to ensure the shortest signal route, and achieves both pure amplification and speaker drive ability rivaling that of separated models.

Balanced Power Amplifier Input Stage

The front stage of the power amplifier has been balanced to achieve clean amplification at low impedance and further increase the dynamic range heard by the listener.

Large-Capacity Custom Power Transformer - The Heart of the Finest Power Amplifiers

As one of the most important factors in deciding an amplifier's ultimate sound quality, the F1's robust power supply plays a critical role in its ability to deliver high power in a linear manner. The power supply's large 1,000VA toroidal transformer provides the foundation for the F1's exceptional power output. With the knowledge that an amplifier's sound quality is ultimately determined by the quality of its power transformer, the F1 employs a custom power transformer that demonstrates Esoteric's highly developed expertise in material selection, core size and even mounting technique.

The power supply also features 40,000µF block capacitors for each channel in a dual monaural configuration. Large-gauge cable is used in all connections to help minimize impedance. This outstanding power section achieves a theoretically linear power output ranging from 30W at an 8Ω load to 60W at 4Ω for faithful reproduction of every musical dynamic.

Low Impedance for Enhanced Drive Capability

The speaker output section utilizes eight 1mm-thick bus bars formed of high-purity OFC and MOSFET switching with no mechanical contacts. This design minimizes signal impedance and enhances drive capability of the F1.

3D Optimized Chassis Construction

The F1's 3D Optimized Chassis features robust construction that gives each circuit block its own dedicated compartment. Interference between circuits is effectively minimized while achieving the shortest possible cable routing. Chassis exteriors are formed of thick aluminum panels manufactured without compromise following the same design philosophy imbued in Esoteric's separate amplifiers. As a result, the F1 achieved a extremely heavy-duty construction not normally found in conventional integrated amplifiers. Our patented steel pinpoint feet* support the F1 at four points in order to minimize the negative effects of vibration.

Optional Board Slot

An optional board slot facilitates the installation of an optional board, such as OP-DAC1 D/A Converter Board or OP-ESLA1 ES-Link Analog Input Board.

Other features

  • Organic EL display (Normal / Large font).
  • Independently adjustable input gains (±18dB; 0.5dB steps).
  • L/R channel balance.
  • Individually selectable phase inversion for each source.
  • Aluminum body remote controller can also be used to operate

On Audio Impact you can find Esoteric Grandioso C1 and many other products related in the Preamplifiers

The C1's separate 29kg linear power supply enables pristinely accurate amplification and ensures that the music signal is delivered to the power amplifiers without any loss of dynamics.. The C1's DC power supply features a fully independent two-channel design with dual AC inputs and DC outputs.. All sections of the amplification circuitry are fully balanced, with the input buffer, volume control and high-speed output buffer laid out three-dimensionally to achieve the shortest possible signal paths.. The C1's source signal is first received by the dedicated buffer amplifiers integrated with each of the five inputs (XLR x 3, RCA x 2), and the circuit configuration is balanced at each stage from there on.. *QVCS=Quad Volume Control System. In its function as a line driver, the preamplifier must have the ability to fully drive the power amplifiers in a way that faithfully conveys music signals that have an extremely wide dynamic range, extending all the way from pianissimo to fortissimo.. The C1's output buffer circuitry utilizes high-performance components to deliver a very high level of current drive, together with an exceptionally high slew rate of 2,000V/μs.. Each output has its own independent drive circuit, and for the XLR outputs, the instantaneous output current capability is maximized by the use of fully symmetrical circuitry for both the hot and cold phases.. Five preset volume curves permit selection of the most comfortable operating feel for the control.. Source component name displays can be programmed using the remote controller.

Esoteric F-03A Integrated Amplifier -

The fold-down door reveals an extensive feature set including selectable phonostage gain, a balance control, three-band tone control, and an A/B speaker switch.. The design and construction are lavish, as you’d expect in a $13,000 30Wpc integrated amplifier.. The F-03A is a distillation of circuits created for Esoteric’s über -expensive Grandioso series, with a fully balanced preamplifier section, dual-mono construction, a switched-resistor attenuator (volume control), and the ball-bearing volume and source-selector knobs mentioned earlier.. I suspect that the $10,000 F-05 is identical in every way to the F-03A except that its output stage is biased to operate in Class AB rather than in Class A.. Class A in general, and the F-03A in particular, doesn’t sound like Class AB solid-state, but neither does it sound like tubes.

Similarly, while other good audio gear has allowed me to hear all the nuances of this detail-rich CD track, I’ve never been able to follow each musical line as easily as with the Grandioso stack.. The level of detail wrought by the Grandioso stack made me want to hunker down and listen to each track just to see what Montgomery would do next.. The same track reveals a soundstage so full and deep, my reference electronics sounded squashed by comparison.. And in other areas, such as dynamics and resolution, the Grandioso stack is among the scant few components I’ve encountered that can go head-to-head with Goldmund gear.. The Esoteric components excel at deconstructing the elements that make up the musical whole.. Esoteric’s answer to the question of how to achieve sonic purity, which here manifests itself as an absence of anything that would distract from immersive musical detail, was to rethink and refine every element of the audio stack..

Even as I was admiring some of the handsomest audio gear I'd ever set eyes on, my thoughts kept returning to equipment of a very different sort.

In an extended Zoom interview with Keith Haas, national sales manager of Esoteric's US distributor, Onkyo USA (footnote 2); Hiroyuki Machida, general manager of Esoteric Marketing and Sales; and Shota Terai, Esoteric digital marketing/social media guru, Machida-san pointed to the fine lines on the face of the power supply and preamp units.. The design goal was "to create the best preamp ever made," Machida-san said of this two-unit dual mono preamplifier, whose outboard power supply requires two 15-amp power cables.. The power supply, designed for dual AC in/dual DC out, includes five transformers: one each for the input and output section for each channel and a separate transformer for the logic-control section.. Other new features include a switchable Line/AV passthrough on all input terminals, RS232 C system control trigger functions, a ±18dB input gain trim that's adjustable in 0.1dB steps, a ±6dB balance control adjustable in 0.1dB steps, and large display fonts.. The power supply's front panel is a thing of beauty, especially when its LED power indicator is turned up and the panel's sculpted lines are bathed in blue.. The rear panel is, of course, more utilitarian, with IEC jacks for each of the two 15A power cables, two outputs for the supplied pliant umbilical cords that connect the power supply to the preamp, two trigger outputs, a signal ground connector for optional use with an SACD/CD player or amplifier, and front-panel LED illumination adjustment.. While I loved to gaze at the power supply's blue illumination, the blue around the main preamp's control knobs did not match the blue readout of its display; I set it to illuminate briefly when I adjusted volume or settings.. The rear panel features two pairs of RCA inputs, three pairs of XLR/ESL-A inputs (footnote 5), two pairs of XLR outputs, two pairs of ESL-A outputs, two inputs for the DC umbilical cords, trigger input, a micro-USB port (for software updates), RS-232C (for system integration), and signal ground connections.

The one design feature of these amplifiers that most clearly reflects Grandioso thinking is their dual monaural configuration, which maintains complete left and right channel independence through all stages, from preamplifier to the power amplifier’s final stage.. Playing a significant role in the F Series’ balanced dual monaural configuration is the proprietary Quad Volume Control System (QVCS), which incorporates a total of four precision switched resistor ladder networks operating in unison to electronically and independently control the left and right channels and their positive and negative phases.. 3-Band Tone Control (Treble/Middle/Bass). Power Amplifier Input Stage Features Balanced Configuration. The power amplification section’s front stage is balanced in line with the thinking behind our S Series separate amplifiers.. As in our separate power amplifiers, this outstanding power section achieves a theoretically linear power output ranging from 30W at an 8Ω load to 60W at 4Ω for faithful reproduction of every musical dynamic.. The PRE-out employs a powerful buffer amplifier, while XLR outputs achieve a highly effective fully balanced configuration.

Even from cold, this 100-watt per channel integrated entices.. A well tempered, dual mono, class AB power amplifier, fed by a massive power supply makes for a dynamic presentation, that is free of coloration.. While the majority of my test listening was done with the onboard DAC and phonostage, Esoteric’s Scott Sefton had to recall the DAC board, leaving the trusty Gryphon Kalliope ($32,000) DAC in its place.. Excellent as the audio performance of the F-07 is, the level of human engineering on this product is equally great; it’s an incredibly easy integrated to live with and use day to day.. The controls are well distributed on the front panel, with input and volume controls larger than the rest to command attention and secondary controls at the ready.. And yes, there is more performance to be had from Esoteric’s flagship components.. All of the components compliment each other and offer an equal level of performance, but the F-07 offers more in every way.. The Esoteric F-07 Integrated Amplifier

Esoteric F-05 Integrated Amplifier

The Esoteric F-05 ($10,000) integrated amplifier is another premier performer from Esoteric with several innovative design choices that can differentiate it from the competition.. The Esoteric F-05 integrated amplifier made an immediate impression when added to my listening room system.. This makes for a more interesting and insightful comparison when paired up with other components.. My own system failings did not allow me to audition the phono stage as originally planned, as my new moving coil phono cartridge proved to be a big time performer but also extremely frail during the setup process.. Of course, additional flexibility would be nice to tweak the sound, but you can not ignore what this phono stage and this cartridge were able to produce together.. Images floated across the soundstage in a nice three dimensional space.. The Wall continues to stand up over time as one of the most powerful Rock concept albums ever released.. This audiophile favorite has been reissued many times.. My preferred release on digital has always been the Classic Records CD, but now we have a new SACD contender from Analogue Productions.. Even if you are not a big fan of classical music, this is a great test for your system and might just expand your taste in music.. The Esoteric F-05 integrated amplifier is a true standout with exemplary performance well beyond its price point.. It can deliver tremendous flexibility with a wide range of both analog and digital inputs and outputs.. Most importantly, it affords that emotional connection and love for music that we all seek out as our highest priority.

Esoteric Grandioso S1 Stereo Power Amplifier now at Analogue Seduction.

The original of ESOTERIC's new S1 Stereo Power Amplifier lie in an unbounded respect for the deep emotive powers of music.. That indescribable sense of spaciousness, the feeling that the music you're hearing is truly live, can only be generated by an amplifier that offers an abundance of power in order to properly drive the loudspeakers.. Employing the finest components, and massive power supplies, enables Esoteric's amplifiers to achieve that high power output.. As our new flagship stereo power amplifier, the S1 faithfully incorporates the design philosophy of our Monoblock M1, setting free every nuance of sound, and imparting to music all the vibrancy and richness of life.. Continuous low bass and repeated fast transients from percussive instruments can impose a very demanding load on the amplifier that can require not only continuous high power outputs, but also repeated bursts of high power.. Unless the amplifier's power supply has the capacity to meet these stringent demands and do so consistently, the dynamics of the music will be compromised.. This is a testament to the linearity of the S1's power supply, and permits the full spectrum of sound dynamics to be faithfully reproduced at all volume levels.. As one of the most important factors in deciding an amplifier's ultimate sound quality, the S1's robust power supply plays a critical role in its ability to deliver high power in a linear manner.. The power supply's large 2,180VA toroidal transformer provides the foundation for the S1's exceptional power output.. With the knowledge that an amplifier's sound quality is ultimately determined by the quality of its power transformer, the S1 employs a custom power transformer that demonstrates Esoteric's highly developed expertise in material selection, core size and even mounting technique.. While this may sound simple, considering that the output current ranges from very small to very large, it is nearly impossible to accurately drive the loudspeakers in a way that is consistently faithful to the source musical signal.. In order to optimize the amplifier's ability to drive the loudspeakers, ways had to be found to reduce the amplifier's output impedance to an absolute minimum.

The Grandioso K1 takes its place at the pinnacle of Esoteric's one box CD players built with the finest luxurious materials expected of a flagship model.

SUPER AUDIO CD PLAYER The Grandioso K1 takes its place at the pinnacle of this range as an all-in-one Super Audio CD player comprised of only the very best in luxurious materials expected of a flagship model.. Esoteric has also developed “ES-LINK Analog”, an original high quality current transmission method for connecting with the Grandioso F1 Integrated Amplifier.. 35-bit D/A Processing for Outstanding Powers of Musical Expression The Grandioso K1 combines multiple 32-bit DAC chipsets and utilises a 35-bit D/A processing algorithm to convert the PCM signal to analog at a high resolution of 35 bits.. Esoteric-HCLD*1: Esoteric’s Proprietary Current-Enhancing Output Buffer Circuit The ability to produce comparatively large currents and high slew rates are two of the most important factors that enable an analog output circuit to accurately transmit the wide dynamic range of a music signal without degradation.. “ES-LINK Analog” Method for High Quality Current Transmission In addition to regular line connections (XLR and RCA), the Grandioso K1 features the new “ES-LINK Analog” transmission method developed by Esoteric.. This is a current transmission signaling that utilises the high performance of the HCLD buffer circuit and its enhanced ability to supply current at high-speed.. USB Support for 11.2 MHz DSD, 384 kHz/32-bit PCM, and Asynchronous Transmission The Grandioso K1 includes a USB terminal for connecting to computers, and the driver and “ESOTERIC HR Audio Player” playback software can be downloaded from the Esoteric website free-of-charge.. High-Precision VCXO Clock Often considered the heart of a digital player, the clock circuit supplies a high-accuracy reference clock signal to the digital circuitry.. The Grandioso Custom VCXO (voltage-controlled crystal oscillator) developed in a joint effort with Nihon Dempa Kogyo (NDK) is a high-precision custom clock that adopts a large crystal element to ensure exceptional sound playback quality with excellent center accuracy (±0.5 ppm) and extremely low levels of phase noise.. Clock Sync Function for Synchronisation with External Devices Connecting the Grandioso K1 to a high-precision master clock generator such as the Grandioso G1 allows synchronisation of the unit’s operation with an external clock signal, thereby enabling the quality of the system to be further upgraded.. This cable adopts a MIL-compliant gold plated SMA connector that was specifically developed for high frequency transmission and an original milled brass BNC terminal designed by ESOTERIC to achieve a secure connection, in order to minimise loss of transmission to the utmost limit..

ESOTERIC COMPANY, which was born in the midst of such transition, shall pursue a unique path as a high-end audio brand, by deploying Super Audio CD players equipped with the VRDS mechanism that has sublimated its original mechatronics technology, as well as D/A converters, network players, amplifiers, and clock generators.

In February 2015, I reviewed Esoteric’s Grandioso P1 SACD/CD transport, D1 mono digital-to-analog converters, and G-01 master clock generator. At a total cost of $91,000 USD, these state-of-the-art components in five hefty cases of aircraft-grade aluminum are not for the faint of checkbook or rack space.

Transport: One of the most critical parts of any disc player is its transport, and in the K1 is Esoteric’s best: the much-revered VRDS-NEO VMK-3.5-20S.. DAC: For each channel, the K1 uses four of AKM’s new 32-bit AK4497 DAC chips.. . . grandioso .. Esoteric’s much more expensive digital stack of Grandioso P1, D1, and G-01 substantially betters the Grandioso K1 in speed, timing, timbral delineation, resolution, weight, transient impact, imaging, and vertical soundstaging..
