LEAK Stereo 230

TURNTABLE READY

Traditional audiophiles will recognise the assured quality in the high-quality, low-noise turntable input of the LEAK STEREO 230. Optimised for moving magnet cartridges, the JFET-based circuit offers precise RIAA equalisation in accordance with de facto industry standards for vinyl record playback.

HEADPHONE USERS

The LEAK STEREO 230 uses a dedicated amplifier circuit with current-feedback technology for the headphone output. Equal in performance to standalone headphone amplifiers, beyond the price class of this complete system, the design offers high-speed output signal transition thanks to a high slew rate. The result is a dynamic, detailed and engaging performance with all manner of headphone types.
