Hi, I'm new to the circle and have just purchased a pair of Dulcet's. I'm mightily impressed. I was wondering what amps people are using. So far I've tried a 2A3 push pull 11w not enough and a Sugden A21 which doesn't do much wrong but I'm sure I could do better. I think around 20w to be a realistic minimum and would prefer integrated if poss. please let me know your experiences.
