GREAT FIRST REVIEW on Audio Appraisal - http://www.audioappraisal.com/arcam-rhead-headphone-amplifier-review/ "The rHead was able to equal the performance of a Sennheiser HDVA-600 at almost triple the price, even surpassing it when it came to musicality and listening enjoyment." "In summary, I simply don’t know how they do it. Another outstanding product from Arcam, and a real credit to the company’s existing product portfolio. At £399 in the UK and $599 in the US, it represents extraordinary value for money. Whether you’re a headphone aficionado or simply looking to add a headphone amplifier to your existing hi-fi system, the Arcam rHead should be at the top of your shortlist. Highly recommended."
