XP-15 Single Chassis

A single-chassis phono stage preamplifier, the XP-15 represents sophistication and maturation of both thinking and component evolution. Each new design of that evolution has brought a steady improvement in measured metrics and flexibility -- greater accuracy in the RIAA curve, a greater range of gain from 46db to 76db...and the list goes on. But more importantly, the evolution has contributed to a more robust sonic image presented with improved resolution and additional sonic ease.

XP-17 Single Chassis
XP17 uses the new-shielded low noise toroid and input filter module, like the XP-12. The power supply has an extra stage of RC filtering.  We have lower radiated and mechanical noise.
The XP17 has an all-new input circuit that is symmetrical and lower in noise and distortion with greater drive capability. Noise is the most prominent part of THD+N in the first section of a phono stage. By lowering noise we get better resolution and dynamics.
Designed with a split EQ network like the XP 25 and XS Phono that is more accurate and can handle greater signal levels.
The secondary stage runs a higher bias output stage with auto bias.
The numerous loading options from the XP-15 are all still available and three gain settings to accommodate low output MC to MM cartridges.

XP-27 Twin Chassis
The twin chassis XP-27 eclipses the already exceptional performance of the well-reviewed and well-received XP-15, XP-25 & XP-17: delivering enhanced RIAA performance at a fraction of the previous distortion.  The new design uses double-shielded low noise toroidal transformers in external supply connected via aviation-grade circular connectors using silver over oxygen-free copper. The power supply is dual mono with two transformers with lower radiated and mechanical noise. Noise is the most prominent part of THD+N at low levels, so by lowering noise we get better resolution and dynamics. The XP-27 input and gain circuitry are similar to that found in the Xs Phono. This means switching and loading are done at higher signal levels, minimising noise and improving low-level performance.

XP-25 Twin Chassis
The twin chassis XP-25 phono stage preamplifier greatly improves upon the already exceptional performance of the XP-15. In addition to a separate and isolated power supply chassis, the XP-25 boasts adjustable gain, two separate inputs, a low cut filter, mute feature, resistive and capacitive loading all on the front panel for easy access.
With the XP-25 you will discover a whole new dimension of dynamics, inner detail and spectral richness.
