NAD 3020i was my first amp but it wasn't powerful enough to drive my Energy speakers and it was a little on the neutral side. You don't have to worry about the capacitors, my friend is still using it now, so far so good. As for myself, I have traded in for an Arcam amp because I wanted something a tad warmer and powerful enough to drive my speakers. If you listen to classical music, NAD 3020i is your best bet.
