The new HD 990 player and HK 990 amp are products with a difference. Actually the CD player isn't quite so unusual, though it does have a few less common features that we'll come to in a minute. The amplifier, though, turns out to be a thoroughly different colour horse. Yes, you put a little signal in one hole and it comes out of another much bigger, but what goes on between the two is – or can be if one chooses – a lot more complex than pure amplification.
