Krell – the Leader in Audio Engineering

 

Krell entwirft und produziert High-Performance Audio- und Video-Equipment für anspruchsvolle Musikliebhaber und Heimkino-Fans. Jede Komponente ist eine einzigartige Synthese aus Wissenschaft und Kunst, für unvergleichlichen klanglichen Realismus.

Die Produkte der neuen Serie ist die ultimative Verkörperung der Krell Forschung und Entwicklung. Der Master Reference Verstärker z.B. stellt die Spitze eines im Verstärkerbau nie zuvor dagewesenen Entwicklungsaufwandes dar.

Die Gehäuse aus massivem Aluminium gewährleisten ebenso Langlebigkeit wie ein unverwechselbares “Look and Feel”.

Roland Spalinger über KRELL:

 

Ich kenne KRELL seit ihrer Markteinführung in den achtziger Jahren als ein US Monument der Verstärkerhersteller. Ich konnte mich als Techniker schon früh von der sprichwörtlichen Qualität der KRELL Produkte bei Wartungen und Revisionen überzeugen! KRELL Produkte haben eine treue und langjährige Anhängerschaft, weil sich der typische «KRELL Sound» über Jahre erhalten hat. KRELL Produkte stehen für Langlebigkeit, Präzision und Power, gepaart mit höchster Ingenieurskunst! Ich bin sehr stolz, Ihnen die Marke KRELL ab diesem Jahr exklusiv in der Schweiz anbieten zu können. Sie können das gesamte Sortiment in meinem Laden ab September anhören und anfassen. Ich freue mich auf Sie!

 

 

Seit über 40 Jahren ist Krell bekannt für die stabilsten Endstufen. Der Name leitete sich aus dem Film Forbidden Planet ab, Dan Dagostino suchte damals nach einem Synonym für Leistung ohne Ende und fand das damals in der Maschine mit Leistung ohne Ende des "Krells".

Krell Illusion II Vorstufe

The Illusion preamplifier extends the Krell tradition of separating the power supply from the audio circuitry in our flagship preamplifiers. Sharing the new Class A iBias power amplifier aesthetic and featuring Krell CAST technology, the Illusion preamplifier is the ideal match for the new Solo 375 and Solo 575 power amplifiers.

 

The optional crossover functionality offers the ability to use a subwoofer/satellite speaker arrangement and still maintain the highest quality sonic performance. Previous to the Illusion preamplifier, this system configuration would require signals to pass through a subwoofer’s lower quality crossover circuitry. The Illusion preamplifier is the centerpiece of a world class audio system where space is at a premium.

 

Crossover Highlights

Owing to Krell’s work in the Modulari Duo Reference loudspeaker, the unique crossover feature is a highly sophisticated option. When the optional board is present, additional crossover menu items become available. Definable parameters include independently assignable crossover frequencies and filter types for the high and low pass sections. Choices include 40Hz, 55Hz, 75Hz, and 100Hz crossover points with 12dB, 24dB, and 48dB Butterworth or 24dB Linkwitz-Riley style filters. The high pass section of the crossover uses the full Illusion preamplifier circuitry for its output stage.

 

Circuitry Highlights

The Illusion preamplifier is a dual monaural circuit design with the left and right channels afforded their own power supply regulation and individual full chassis sized boards. All signal gain is realized in surface mount topology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs 1.5 MHz open loop bandwidth in a zero feedback, balanced, Krell Current Mode design terminating in Krell CAST. A complete Krell system (source, preamp, and amplifier) system, connected using CAST interconnects reduces the number of voltage gain stages to the minimum, one. The resulting noise floor approaches the theoretical limit of technology. Negative feedback is not used anywhere in the preamp, nor is it necessary. Open-loop distortion is typically less than 0.003%. The volume control is realized with a balanced resistor ladder — bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting.

 

Power Supply Highlights

The Illusion audio circuits receive power from a Krell Current Mode analog power supply housed in its own dedicated chassis. The power supply avoids the common integrated circuit topology used in many preamplifiers and instead mimics the design topology of Krell Evolution e Series amplifiers. The circuitry is completely discrete giving it the ability to respond quickly to current demands and also be unaffected by all but the most severe AC voltage power fluctuations. Oversized for a preamplifier, the power supply features a 290 VA transformer and 41,600µF of capacitance. Locating the power supply in its own chassis presents the ideal configuration for isolating stray electrical and magnetic interference from the critical preamplifier signal path. Capable of delivering current and voltage swing for any musical event, the Illusion power supply is gentle on AC requirements when not in use. A new eco-friendly design reduces standby power draw to 2W.

Krell Illusion Vorstufe

The Illusion II is the perfect centerpiece for a world class digital and analog audio system. Added to the normal selection of balanced and single- ended inputs are five digital inputs. The digital module features AES/EBU, coaxial, and optical digital inputs for use with streaming devices or other digital sources.

 

Circuitry Highlights

The Illusion II preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero feedback, balanced, Krell Current Mode design, the Illusion II shares the same design philosophy as its bigger brother, the flagship Illusion preamplifier. Negative feedback is not used anywhere in the preamp, nor is it necessary. Open-loop distortion is typically less than 0.003%. The volume control is realized with a balanced resistor ladder - bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting. The headphone circuitry is identical to the main circuitry, offering private listening with the same performance as speaker playback.

 

Digital Module Highlights

The digital module supports up to 24 bit/192kHz LPCM. All digital signals are fed to an ESS Sabre DAC and then sent to Krell’s Current Mode, discrete, balanced analog circuitry.

 

Power Supply Highlights

Oversized for a preamplifier, the power supply features a 95 VA transformer and 40,000 µF of capacitance giving it the ability to respond quickly to musical demands. The large power supply improves noise rejection and renders the Illusion II impervious to all but the most severe AC voltage power fluctuations. A new eco-friendly standby mode reduces power consumption to 2W
