Ultrasone Introduces Custom Headphone Amplifiers

Ultrasone of America LLC, the U.S. distributor for German headphone manufacturer Ultrasone AG, is introducing two new amplifiers created exclusively for the company’s product line. The RPX-33 ($1,799) and NX-02 Sistema ($875) were designed and built by Italian manufacturer RudiStor Sound Systems for use with Ultrasone’s PROline 750, PROline 2500 and Edition 9 headphones.

The all-discrete RPX-33 dual mono topology headphone amp is designed for the shortest possible signal path. Its power supply uses a capacitance multiplier to deliver pure DC power. It promises high transparency, deep and full bass response, and refined mid- to high frequencies. Two headphone output jacks are provided: one for high sensitivity with lower power (L), and the other for low-sensitivity headphones with higher output (H).

Designed especially for the Ultrasone PROline 2500, the NX-02 Sistema is an IC-based amp that further enhances the PROline 2500’s sound. It promises exceptional sonic detail, a tight, powerful bass and clear highs.

Ultrasone offers the RPX-33 amp, Edition 9 and Ultrasone iCans as a package for $3,299. The NX-02 Sistema amp can be purchased with the PROline 2500 for $1,199.

Ultrasone will exhibit at the 2007 Winter NAMM Show in Anaheim, Calif. from January 18 through 21 in booth #6799.
