My experience is the same as Slv's; I've now got one on each of three dedicated lines. An important caveat, though, is that it sounded exactly like S23chang described when I first inserted it into the system. My dealer warned me, and he was right, that you have to give it about three days to run in (get the transformer saturated, I don't know?) before listening to it seriously. Then it will perform at its best.
