As a headphone amp the tonality matching with the HD800 is almost perfect and for other headphones it plays to obvious strengths. The transparency of the CMA800r is top notch, so much so your DAC will be under more scrutiny than you think so choose wisely to get the best out of the amp.
Would I go monoblock with two units as a headphone user? It’s interesting but debatable on the value scale but certainly unbalanced output more than excels and at $1500 its not overpriced for what it can achieve with flagships and mid-fi cans alike.
At the time of writing the Questyle team are selling this through Ebay and Amazon and one to two distributors in the US market and beyond.
