XSP-1

Differential Reference Preamp

$1,199.00
High-performance add-on external phono preamp for moving coil and moving magnet cartridges.
  • The XSP-1 is a high-quality stereo analog preamp, featuring a fully balanced signal path, high quality relay signal switching, a precision analog ladder Volume control, a high-quality phono preamp that supports both moving magnet and moving coil cartridges, and precision tone trim adjustments.

    Analog Stereo Performance: Taken To The Next Level

    Our all-new XSP-1 Gen 2 balanced preamplifier isn’t just a great cosmetic match to our Gen 2 power amps—it also takes performance to a new level. Thanks to an all-new surface-mount design, we’ve significantly tightened component tolerances, shortened signal paths, and matched the trace lengths between channels, for a greatly improved acoustic signature.

    Refining Balanced Performance

    The XSP-1 Gen 2 combines a pure, all-analog, audiophile topology with an advanced digital control system. This maintains the purity of the audio signal, while offering advanced features, resolution, and accuracy far surpassing traditional designs. The XSP-1 Gen 2 delivers an uncompromised listening experience in Reference Playback mode by totally avoiding single ended to balanced conversions from the signal path. Combined with instrumentation grade relays for input selection and high voltage, and a digitally-controlled analog resistor ladder network with 0.5dB per step resolution for volume, the XSP-1 Gen 2 maintains signal integrity and near perfect channel matching – even at very low listening levels.

    The Control You Need

    In terms of fine-tuning the sound of your system, most audiophile preamps are “take it or leave it”, offering little or no control over the interaction between your speakers and room. Not the XSP-1 Gen 2. It includes precision contour controls that allow you to tailor the high frequency and low frequency response of your system for perfect results in your listening environment. For absolute neutrality, the contour controls operate by switching networks of precision discrete tuning components in and out, and can, of course, be completely bypassed.

    Advanced Features Ease System Integration

    The XSP-1 Gen 2 packs a long list of features that make it the ideal centerpiece for your high performance audio system. It includes analog bass management for perfect integration with 2.1 or 2.2 systems, as well as a high current, load-invariant headphone amplifier, an external signal processor loop, trigger inputs and outputs, and a full-featured milled aluminum remote control. A large VFD display shows system status messages and provides visual confirmation of all actions and settings.

    Ready for Legacy Sources

    Unlike many other preamps these days, the XSP-1 includes a truly stunning and extremely quiet phono preamplifier with inputs for both moving magnet and moving coil cartridges (with user-selectable loading)

    The list of features can go on and on…but the real proof is in the listening experience, and in the XSP-1’s incredible flexibility and ease of operation.
