    Dette er hva Robert E. Greene skriver:
    This latest version of Roger Sanders` longtime work on electrostatic speakers IS A GREAT TRIUMPH of audio design.
    The system is in many ways all but incomparably good, exploring the boundaries of what is possible in audio now or in foreseeable future.
    And when one considers the reasonable price, the achievement becomes even more startling and impressive.

    Imaging is spectacularly precise and three-dimentional, when the recording justifies that.
    One has a sense of hearing into the recording venue that is hard to attain otherwise.
    And the ultra-neutrality really makes instruments sound right.
    On its own terms ( of controlled pattern ), the Sanders` 10e system sets a new benchmark in speaker design.

    Oversatt til norsk:
    Den siste versjon av Roger Sanders mangeårige arbeid med elektrostatiske høyttalere er en stor triumf innen audio design.

    Systemet er på mange måter uten sammenligning godt, og utfordrer grensene for hva som er mulig innen audio, nå og i en overskuelig framtid.
    Sanders`10e system setter en ny standard innen høyttaler - design!!


    Systemet inkluderer:
    •Elektrostathøyttalere ( hybrid )m/ et dynamisk basselement med en superlett aluminiumsmenbran - for å matche hurtigheten i elektrostaten.
    •Magtech - 2 x 500W ( 8 Ohm ) effektforsterker ( spesielt designet for drift av elektrostathøyttalere )
    •Nytt LMS (Loudspeaker Management System) includerer et elektronisk/digitalt eksternt delefilter med et romkorreksjons-system, Digital Signal Processor, og "Real Time Analyzer" / frekvensmåler og mikrofon.

    Evig garanti på elektrostatpanelet!!

    Sanders opererer kun med helt flate elektrostatpaneler - for å unngå absolutt maksimalt med romrefleksjoner
    Ekstremt gjennomsiktig
    Ekstremt liten forvrengning
    Spiller all slags musikk
    Kan spille HØYT ( om det er nødvendig eller behov )

    Pris: kr 191500,- ( inkludert MAGTECH effektforsterker til kr 65900,- ) ( inkludert eksternt delefilter og romkorreksjons-system )

    Man trenger en effektforsterker i tillegg i dette systemet


    Klippet fra Sanders Sound Systems::
    Sanders Sound Systems has been producing the most advanced and sophisticated speakers available for many years. We do not compromise. We use only the best technology, which includes electrostatic midrange/treble, transmission line bass, digital electronic crossovers with electronic time alignment, and biamplification using the unique, voltage-regulated, Magtech amplifier.

    However, a truly State-of-the-Art loudspeaker must also include an RCS (Room Correction System) since even a perfect loudspeaker will have its frequency response degraded by the room/speaker interaction and bass resonances produced by room dimensions. Any speaker that does not use an RCS is simply not performing to its full potential.

    Additionally, a S.O.T.A. ( State Of The Art )speaker needs a DSP (Digital Signal Processor) so that the user can tailor the speaker's frequency response to compensate for deficiencies in recordings and to best match his personal preferences in how his speaker system should sound.


    An S.O.T.A. speaker needs an RTA (Real Time Analyzer) so that the user can actually measure the frequency response of his speakers and room. Only then can he have the information needed to actually know how to adjust the frequency response of his system -- instead of just guessing and trying to optimize it "by ear."

    When all these features are combined with a modern, digital crossover, the resulting component is called an LMS (Loudspeaker Management System). Unfortunately, there has been no comprehensive, simple to operate, self-contained, practical, and automated LMS available until recently.


    Sanders Sound Systems has finally developed the first, truly S.O.T.A. speaker using all the technology and features available in an LMS in the new Model 10e speaker system. The Model 10e does not require an outboard computer to operate, has an automated RCS, includes an independent RTA, and makes it possible for the owner to infinitely tailor the frequency response of the audio system to whatever degree he feels necessary.


    When these advanced electronic features are combined in an electrostatic loudspeaker with transmission line woofer system, the result must be heard to be believed.

    This is truly a State-of-the-Art loudspeaker system that has no peer.

    Speakers and Electronics are manufactured in Conifer, Colorado.

    The popularity and success of the Electrostatic Amplifier (the "ESL Amp") for driving electrostatic speakers led to many requests for a companion amplifier that was specifically designed for driving conventional magnetic speakers. Two years in development, the Magtech amplifier is that amplifier.

    DESIGN PHILOSOPHY

    Magnetic speakers differ from electrostatic speakers in one fundamental way -- they require massive amounts of current and power. This causes the power supply voltages in an amplifier to change dramatically (typically by 30%) between idle and full power.

    Electronics have their lowest distortion and optimum performance at a specific design voltage. If the voltage varies, the amplifier's performance will suffer.

    An additional problem in amplifiers is that they require bias to eliminate crossover notch distortion and determine their class of operation. The bias will vary as the voltage does, which will further reduce performance.

    An amplifier's voltage will fluctuate wildly as dynamic music is played. This causes the amplifier's distortion and bias to vary constantly and fail to meet its full performance potential.

    As if all these problems are not enough, as an amplifier's voltage sags under load, the power it can deliver is greatly reduced. If the voltage would remain stable, the amplifier could produce much more power. Since most audiophile speaker systems require several hundred watts of power to avoid clipping and compression of the dynamic range, power is extremely important.

    THE SOLUTION

    All quality, line-level electronics use voltage regulation in their power supplies to produce a stable voltage, regardless of load or the mains voltage. Audiophiles would not consider using a source component that did not have regulated power supplies. So why use amplifiers with unregulated supplies?

    The main problem is heat. Amplifiers operate at much higher voltages and currents than line level source components. These higher voltages and currents forces conventional regulator designs to waste large amounts of energy, which wastes expensive electricity and causes the amplifier to get very hot.

    Also, many regulator designs radiate RF (Radio Frequency) energy when switching high currents and voltages. This RF gets into the amplifier's electronics and can cause instability, oscillation, and noise. As a result of these problems, modern power amplifiers do not use regulated power supplies and fail to take advantage of the benefits available from doing so.

    Sanders has solved these problems by developing a voltage regulator that is essentially 100% efficient. There is no heat dissipated by the regulator system. There is no high-power/high-voltage switching that causes heat generation or RF problems.

    The regulator in the Magtech amplifier maintains a stable voltage regardless of load or reasonable changes in the line voltage feeding the amplifier. It runs stone cold, produces zero RF energy, and is simple and reliable.

    Unlike other amplifiers, the distortion in the Magtech amplifier is virtually unchanged regardless of power level. The bias is stable regardless of load.
    The regulator makes it possible to obtain a 50% increase in power over the same amplifier operated unregulated. In its stereo form, the Magtech will deliver 500 watts/channel into an 8 ohm load and 900 watts/channel into a 4 ohm load.

    The Magtech is built into the same chassis as the ESL Amp, so it is compact enough (17" wide, 5-1/2" tall, 14" deep) to place on a shelf or into a cabinet. It is also light enough (54 pounds) to be picked up. Like the ESL amp, it runs very cool and may be left on continually without concern for power usage.

    The Magtech amplifier also uses the same advanced technology that makes the ESL amp able to drive the most difficult loads without performance-degrading, protective circuitry. The Magtech amplifier is the only amplifier on today's market that features a linear voltage regulator. The result is a compact, yet extremely powerful amplifier that is ideally suited to driving the most difficult magnetic speakers.

    Då eg hadde "oldefaren" til desse høgtalarane, var eg svært fornøgd. Og med spesialtilpassa, effektrik elektronikk (tenkte aldri på at ein treng så mykje guffe då eg hadde dei opprinnelege modellane, men det var andre delefrekvensar den gongen), og ikkje minst det nye LMS-systemet for justeringar, vil eg tru dette er eit riktig så fornuftig konsept.

    Utvilsomt et spennende konsept Mr. Sanders har utviklet.
    Det hadde vært ønskelig å få lyttet til musikk via dette systemet for å danne seg et bilde av hvordan de formidler musikk i forhold til andre ESL merker. En tur til Nodeland må vente, så pr nå må man nøye seg med omtalen.

    Har et Sanders Sound System (snart 10 år). Veldig fornøyd! Det nye har vel ikke blitt noe dårligere med åra! Et råbra alternativ til andre elektrostater.
