Arcam is one of the most underappreciated lines out there. I had an Alpha 9 integrated and an Alpha 8 CD for a long time. The CD player was replaced by the Yamaha, but it wasn't an easy choice. What the Yamaha gave me in dynamics, bass, and transparency, came at the cost of losing that Arcam smoothness and utter musicality. One had to go and the Yamaha was doing double duty as a DVD player. Ex wife was a TV addict.
The Alpha 9 amp was very easy on the ears. Just something so right about it. Yeah, they tend to make a lot of things sound harsh and aggressive...amusical. And the bass definition is hard to beat until you spend big bucks.
