The Revelation Series bridges a gap in the Constellation Audio product hierarchy. Building on the Inspiration tradition and offering improved performance due to the use of carefully selected parts, the Revelation Series is a logical step up from Inspiration. Its distinctively Constellation casework design draws upon the heritage of the Reference Series and extends the foundation first used in I...[more]

Building on the legacy of the Momentum HD Preamplifier, the Momentum C2 topology utilizes an array of four JFET transistors in a complementary, differential, push-pull arrangement, dramatically increasing input impedance and reducing noise. Its unique, discrete dual-complementary differential JFET input stage achieves exceptional performance and stability in every system configuration. ...[more]

Locked inside those grooves is the most realistic and natural sound one could ever experience. The Momentum Phonostage extracts every last bit of music hidden in this microscopic landscape. Combining the finest possible analog circuitry with the precision of digital control, the Momentum Phonostage offers vinyl lovers unmatched flexibility. Front panel pushbuttons control gain, loading ...[more]

A 300 VA power supply in a separate chassis isolates the preamp’s sensitive circuitry from electromagnetic interference and noise. Separate supplies power audio and control circuitry, so the control circuits are completely isolated from the audio circuits. The styling of the Momentum preamp perfectly complements the Momentum amplifiers, with copper accents to match the amplifiers&rsqu...[more]

Instead of offering a preamplifier based on the same approach as that of our competitors, we at darTZeel chose to think differently, offering for the first time in the world what previously seemed impossible:  No contact or switches or relay of any kind for the selection of the sources. This revolutionary feature brings a new level of transparency. Instead of routing the signal through a...[more]

Fully complementary circuitry: The Perseus's balanced audio circuitry is essentially two mirror-imaged preamp circuits, one to amplify the positive half of the audio signal, the other to amplify the negative half. The fully balanced design cancels the effects of interference-an important capability considering the low level of the signals inside a phono preamp-and also increases slew rate and f...[more]

Foundation PH9 Phono Preamplifier The PH9 phono preamplifier is a great pairing with most cartridge and turntable combinations. A trio of 6H30 vacuum tubes are at the core of a simple and clear signal path to provide the most transparent preamplification possible. Five different impedance settings allow for cartridge loading, which can be changed on the fly with the included metal rem...[more]

The KAV-280p is a superb sounding stereo preamplifier that brings the dynamics and resolution of separate components to the KAV Series. Balanced, direct-coupled circuitry is utilized from input to output, and the level attenuator is accomplished with a unique, digitally controlled analog circuit. Balanced and single ended inputs and outputs are supported. The custom-machined aluminum enclosure is ...[more]

The KPE Standard Phono Preamplifier accommodates moving coil and moving magnet phono cartridges. Highlights Composite circuitry applies dual cascaded amplification levels to provide high gain (64.5dB) with low noise (-71dB for moving coil and -89dB for moving magnet) to create astonishing imaging and the high resolution of low-level details. A wide range of impedance selections allows the user to...[more]

The Reference KPE is optimized for use with moving coil phono cartridges. The Reference KPE comes factory set with a 70 dB gain and a 100 Ohm load impedance setting. The available gain settings include 58, 64, 70, and 76dB. Cartridge loading choices include 10, 25, 47, 100, 249, 475, 825, and 1000 Ohms. ...[more]
