I was spoiled in the sense I heard a Boulder 1010 and 1060 with Sasha watt puppies and the sound was glorious, open, refined, and accurate. Sure the electronics cost more than my set up, but it was more refined, realistic, and engaging than the 500 series I had heard. I do not think its a question of not like but after many years with Naim I just heard something that was more precise and more what I was looking for. Naim is "polite" but not as open, or precise as Boulder or D'Agostino or some others I have heard.
