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]

Constellation Audio, the renowned luxury goods manufacturer of high performance solid-state electronics, is pleased to announce the introduction of the new Revelation Series of components at CES 2017. CEO Dr. Murali Murugasu challenged his dream team of designers and engineers to develop a new series of Constellation Audio components that could deliver the essence of our renowned Performance Se...[more]

We like to say the Inspiration PREAMP 1.0 is distilled, not diluted. It embodies the essence of our earlier work while retaining the subjective musicality and objective performance that won so much acclaim for our previous preamps. The most vital technology in our preamps is the Line Stage Gain Module, a fully balanced amplification circuit that uses servos to maintain a pristine balance be...[more]

The left side of the front panel contains a 7” (diagonal) interactive touch-screen display that allows the user to easily control almost all functions. After the initial turn-on sequence, the Volume, Input, Balanced/SE, Stereo/Mono, Phase 0/180, Balance (leftright) control, Mute/Operate, and Settings icon are clearly displayed. Touch the input displayed (such as Tuner), and all of the inputs...[more]

REFERENCE PHONO 10 PHONO PREAMPLIFIER Vinyl record playback has been an integral part of Audio Research since our founding in 1970. Think back to the great phono stages built into the defining preamplifiers of their day, among them the SP3, SP6, SP8, SP10, and SP11. Even after the introduction of the compact disc in 1982, phono sections remained a revered part of our preamplifiers. The firs...[more]
