NuForce Primo 8: Aesthetics



Introduction

Since its establishment in 2005, NuForce of USA has been building a great reputation as an audiophile equipment manufacturer by offering a wide range of products, from a high-end Class-D amplifier to a small portable speaker. And in March of 2014, order to accommodate the specific needs of the audiophiles who rather prefer portability, the Californian company finally launches its first multi-balanced armature transducer driven IEM, Primo 8.


Not to mention its quad-driver configuration, according to the manufacturer, Primo 8 comes with two key innovations: A special patent-pending cross-over network design, which offers phase coherence throughout the frequency spectrum, and a multi-layered star shaped Litz cable joined with a MMCX connector.


NuForce Primo 8: The firstborn



Disclaimer: Data presented here have been acquired with a pair of stock silicone sleeves inserted at 3mm away from the reference plane of the occluded ear simulator, unless stated otherwise.

Primo 8 is the very first quad-driver in ear monitor from an American audio manufacturer, NuForce. While NuForce's technological expertise have been verified repeatedly with their high quality Class-D amplifiers, their reputation as a headphone/IEM company still seems to be quite equivocal to enthuasists. Consequently, this first born child shall serve as a showcase of what the manufacturer is capable of.
