XP-15 Single Chassis

A single-chassis phono stage preamplifier, the XP-15 represents a 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, 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 is done at higher signal levels, minimising noise and improving low level performance.

XP-25 Twin Chassis
The twin chassis XP-25 phonostage 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.
