I'm surprised there isn't a thread for this guy, so I'm starting one. Product page: http://www.arcam.co.uk/products,rSeries,Accessories,rHead.htm John Grandberg (@project86) put the rHead on InnerFidelity's Wall of Fame. The Master Switch listed it as one of the best headphone amps of 2018 while stating, "we’re going to go on record and say that this might be one of the best solid state amps we’ve heard." Well, these guys have heard more than their fair share of audio equipment, and I just happened to be on the market for a new signal chain for my Sundara. After the disappointing pairing between the Massdrop CTH and the Sundara, I have been on the lookout for a great class A solid state amp, and despite this amp not being well marketed on my freedom and fast food side of the pond, I felt it was a no brainer to pull the trigger on the Arcam rHead. It arrived today all the way from the Queen herself. What are my impressions? Well, as I told a friend: Or, more likely, I'll just keep on listening. As of this post, the rHead is available on Analogue Seduction for roughly $250 shipped to the US when it once MSRP'd for a buck shy of $600. In my opinion, for this level of engineering and sound quality, it's an absolute steal. My Sundara has never sounded so good.
