I have a simple question, but a long ramble: Does your AXR85 amp have a slight hum? I presume it's a power hum in the casing, because it's not coming through the speakers. You do have to get your ear really close up to it, on the left-hand side, to hear it. I have other modern amps that don't hum this loud. It's not the most high-end system, so I wonder if it is just how it's meant to be and I'm being pedantic. My Arcam has a very faint power hum, but that is putting my ear against the casing. I have an Onkyo mini-system on the bedside table next to my pillow and that one is quiet, but if the CA AXR85 was in the same position it would be annoyingly noisy. Fortunately, my listening position is usually far enough away, but I wonder if there is a quality issue with my particular amp. With quiet music, if you were sitting next to the amp, you could hear a subtle hum and that seems wrong to me.
