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.
