Gathered from hf thread: Based on the headphone output circuitry from their 5060 Centerpiece Desktop Mixer, the RNHP is a dedicated 24V reference-quality headphone amplifier with level & impedance- calibrated +4dBu Line, unbalanced RCA, and 3.5mm inputs, housed in a rugged VESA- mountable steel chassis. It is designed with near-zero output impedance and high- power, high-headroom circuitry to drive any headphones on the market without compromise. From Rupert Neve Designs: “Whether you’re tracking, mixing, or just listening to music, your headphone amplifier is as important to the final sound quality as your headphones - yet the world is full of headphone amps with compromised sonics, headroom, and power. To address these shortcomings and provide a new level of clarity, Rupert and his team have developed the RNHP." MSRP of $549 USD Apparently folks call Rupert Neve an "audio god". As per Jude (the most trustable) person at least. Jude also apparently has been using this amp as a reference amp with his measuring rig as per his sneak peak video on the upcoming cam jam London. What do you guys think? Has anyone here heard this amp?
