NuForce, Inc., a leader in professional and consumer audio gear, introduces today a world-class combination preamp and headphone amplifier intended for the audio enthusiast for whom quality headphone listening is a top priority. The HAP-100's innovative design combines a number of features never before available at its modest price point. For unprecedented performance, we've implemented the same technologies employed in our flagship P-20 preamp, in union with other precision, audiophile-grade features. The cornerstone of any great audio system is the preamp. It should offer true musicality along with the lowest possible levels of noise and distortion. It should also provide enough inputs to accommodate good system flexibility, not to neglect elegant style and ease of use. For a great many of today's audio enthusiasts, quality headphone listening is a critically important requirement. We've designed the HAP-100 to address this need and more.
The HAP-100 incorporates the volume control technology we first developed for our flagship P-20 preamp. At the unit's core is a switched-resistor ladder network of low-noise, thin-film resistors, one per volume setting, permitting discrete, high-resolution increments of 1dB for each of the HAP-100's one hundred volume steps. In welcome addition to the volume control's fine-adjustment precision, the signal's passage through a single, high-quality resistor at all settings ensures minimal sound degradation.
Following this, a pristine, zero-negative-feedback preamplifier stage delivers vanishingly low levels of distortion, crystalline accuracy and genuine musicality. A true minimalist design, the preamp incorporates an extremely low-noise FET input stage and single high-quality capacitor in the entire signal path.
The HAP-100 is built on a platform that provides the unit's audio circuits with the purest DC power. With its toroidal transformer for minimizing magnetic-field interference and capacitor bank's massive energy reserve, the HAP-100's linear power supply delivers explosive dynamics and lightning-fast transients. The HAP-100's specs are nothing short of stellar: THD+N of less than 0.001% and a dynamic range in excess of 110 dB for the subtlest of musical details against the blackest of backgrounds - without a hint of coloration. Its performance, features, style and price are bound to delight.
