EternalArts uses its brand name to revitalize high-quality concepts of the past that were not fully appreciated at the time or have since been discontinued. These older designs are rejuvenated using the latest technology, equipped with high-grade, modern components and marketed throughout the world.

Logo EternalArtsThe first product in the EternalArts line was the OTL tube amplifier, based on a design by Julius Futterman. This was produced as a limited edition in 2004 and is now extremely difficult to obtain. The years from 2004 to 2008 saw the construction of triode amplifiers with the famous AD1, 300B, 2A3, 45 and 50 triodes. Produced in limited series or as one-off products, these amplifiers revived the charm of these historic tubes. In order to properly evaluate these tube amplifiers, a high efficiency speaker was also developed, equipped with the famous Saba chassis from the 1950s. At the High End 2008 in Munich, the largest trade fair of its kind in Europe, EternalArts was able to proudly present a completely revamped version (Mk II) of its superb OTL amplifier in a modern look. The next products in the program appeared in 2009, and other outstanding components continue to be added to the line right up to the present day.

EternalArts Full Tube Preamplifier FTP

The FTP extends the EternalArts series by a modern version of a classical Stereo preamplifier, which is completely based on tubes. It combines versatile equipment and modern ease of use with exquisite tube sound. Thanks to its design and tonal capabilities, it sets a new benchmark for preamplifiers with tube technology and it will make history.

A full-featured  premium class preamplifier, operating totally on vacuum tube technology– refined through up-to-date technology and manufacturing. Designed with two high quality, variable phono-input-stages as reference to Vinyl-Enthusiasts.The possibility to adjust these for nearly every pick-up system by altering their input impedance and their input capacity is especially interesting for vinyl listeners.


EternalArts OTL Mark II

Julius Futterman´s cicuitry is as ingenius as simple: the speakers are directly connected without an output transformer. Consequently, the impulsivity is considerably higher and the reproduction of the wave form of the musical signals is more accurate. A circuitry without an output transformer has the advantage of lower and upper threshold frequencies because no limitations through winding capacitance and leakage inductance of the transformer become operative. 


EternalArts OTL Mono Blocs MB

Following the tradition of the amplifier line of the great Julius Futterman, the new EternalArts OTL Mono Blocs succeeded his famous models on the occasion of the High End 2009 in Munich. Julius Futterman named his very powerful mono amplifiers H-3aa. The EternalArts mono blocs are the forceful upgrade of the proven, highly stable and effective advancement of the EternalArts OTL circuitry variation.

After several real life tests of the OTL Mk II, in which two OTL Stereo-amplifiers were configurated in parallel,  we could discover the same sonic virtues for which the Mk II is praised. As entry stage and driver have been powerful enough to also feed the main amplifier section with eight beam power tetrodes, the monos were designed with the same technical elements and parts used in the OTL Mk II. They now round up the line for higher demand for power output.                  


EternalArts Stereo Power Amplifier PAS

 The PAS stereo power amplifier 'magic eye' developed by EternalArts is suitable for all musical situations. It is a classic, discrete transistor output stage in a double mono structure with a level indicator via 'magic panels' that can also be switched off.



EternalArts Universal Tape Stage

"Reel-to-reel tape is the new vinyl" - wishful thinking or hype? If you confirm this quote, the return of the tape machine as a classic analog source has not gone unnoticed. Despite their age of 30 and more, a large number of tape machines are still in use today. The high-quality tape machines originally used in professional studios have found their way back or to audiophiles, where, however, often enough they cannot show their actual quality. This topic was important to us to develop the link between a studio machine and the high-end hi-fi system of the audiophile - the EternalArts Universal Tape Stage. The EternalArts Universal Tape Stage ideally connects professional analog tape machines that do not have amplifiers or control instruments with studio peripherals or audiophile high-end hi-fi systems.


EternalArts Dipole

Just as a transformer-less (OTL) tube amplifier comes closest to the goal of having a wide open dynamic, accurate music reproduction, a loudspeaker cabinet that does not influence the sound has proved a stubborn challenge for both, loudspeaker designers and audiophiles.

EternalArts has, in collaboration with the renowned loudspeaker manufacturer 'ECOUTON Audiolabor' newly interpreted the principle of an open system in a compact 3-way dipole loudspeaker.
The result is a 16 ohms fullrange dipole with dimensions of 125,5 x 37 x 26 cm. In its impressive piano black laquered finish, it must be one of the most compact grand loudspeaker systems available and with its high impedance, it is an ideal partner for our OTL amplifiers and of course for any other high quality tube amplifier.



EternalArts DVB-S Tube Audio Satellite Tuner DT

As a combination of a digital tuner stage for the DVB satellite system and the finest tube technology, EternalArts presents a DVB-S satellite tuner with tube output stage. The result is an extraordinary tuner, which from now on represents the ultimate of radio reception.

Listening to  radio in its highest evolutionary step. The most modern and sophisticated Tuner concept in combination with a fine cathode follower tube output stage after classic pattern. Never before radio has been that versatile and fascinating. The ARD alone transmit about 60 channels to a transponder of the satellite ASTRA, which can be received with 338kBits/s and 48 kHz sampling frequency.

With the Eternal Arts Digital Tuner DT, Sample Rate Converter and the D/A Converter are inertia divergent. The extraordinary sound of the tube output stage refines the high quality radio program. Combined with the most modern ease of use: All functions are accessible via the infrared remote control. Or you could control every function with the single button on the device.


EternalArts OTL Headphone Amplifiers

The EternalArts OTL headphone amplifiers are the application of the brilliant Futterman-idea on a tube amplifier for headphones of highest quality. The compact amplifier module is designed to connect two high-impedance HiFi-headphones. The board works with its electronic components inside the two-piece powder-coated sheet steel housing with high gloss black acrylic front, gold, nickel or rubber feet and a volume knob made of solid metal or acrylic.


The amplifier family - KHV, "basic line" and "professional" - was developed and optimized on the high-end headphones HD800 by SENNHEISER. After the first tests with a variety of low-impedance headphones it appeared that with a tiny modification an equally outstanding interaction with other types was given. Consequently a new board was designed for the unmodified circuit, which received a small switch with the optimal setting for low-and high-impedance headphones to be made ​​from the outside. You recognize the new board by the blue EPCOS film capacitors in the cathode outlet.


The circuit design is the "basic line" with a total of 2 and the KHV and "professional" is designed with 4 tubes: 2 triode pentode at the "basic line" and in addition 2 stabilizer tubes for KHV and "professional" for gain-independent stable anode voltages of the amplifier tubes. As with the other OTL amplifiers of the house also a board-supported design with gold-plated tracks laminated on both sides of 70μ was selected. Along comes a grouted TRANSTEC voltage transformer used in toroidal winding and protection technology with Mu-metal shielding. Only high quality matched components, including a classic RUWIDO-Poti in cast aluminum housing (first series) and the legendary blue ALPS potentiometer were used. Gold-plated headphone jacks and gold-plated Neutrik RCA jacks complete the equipment. The circuit is absolutely secure and stable for maximum safety and very high tube life. All in all, a phenomenal transmission bandwidth and pulse sequence was reached.


In May 2013 on the occasion of the High End Munich, EternalArts awarded the imaga hifi Award for the Headphone Amplifier KHV






EternalArts Tube Digital Player DP

The EternalArts Tube Digital Player DP is a high-end CD player in combination with a high-quality tube output stage based on the classic model. It has a high-quality sample rate converter and a DA converter from Burr Brown. This multibit D/A converter 24 bit 192 kHz allows a variety of resolutions and conversion rates.

An ingeniously simple operating concept is given by one-button operation on the device and an IR remote control.



EternalArts HLP – combined Headphone Amplifier and Line Level Preamp

After the highly acclaimed Futterman OTL Mk II, which made its debut at the High End 2008, other tube-based components gradually followed - powerful OTL monoblocks, an extraordinary preamplifier for vinyl enthusiasts, a CD player with a tube output stage and probably the only radio receiver in the world based on the DVB-S standard and with a tube output stage.

This was followed by an extraordinary dipole loudspeaker at High End 2010, which immediately moved into the absolute top of the range on the world market.

The following year, the trend towards “personal audio” at EternalArts led to three high-end headphone amplifier models in OTL technology, designed for top-quality headphones. All models were also unanimously classified by the trade press in the absolute top class of the range.

In order to fulfill the obvious wish to have a high-quality audiophile pre-stage available at the same time as a headphone amplifier, a new product was developed: the EternalArts HLP. The compact component is a high level preamplifier with three inputs, which was created on the basis of the circuitry of the headphone amplifier. Thus it benefits from the ingenious basic concept of voltage stabilization, which was introduced by Neumann in the 1940s for feeding condenser microphones.

The special development effort for this puristic high-level preamplifier was due to the fact that both modes of operation – headphone amplification and signal pre-amplification for an output stage – have different requirements. In one case it is a power supplier to drive converter systems, in the other to supply voltage to control output stages.

Thanks to an ingenious switchover, the new EternalArts HLP does justice to both tasks and creates a sound image of outstanding calmness, splendor of color and attention to detail in both.

The EternalArts combination of a high-end preamplifier with headphone amplifier transfers the ingenious Futterman idea of ​​a transformerless tube amplifier to a compact, puristic high-end switching center for all types of power amplifiers and active monitors.
