What is so great about them is that they are usually a very simple design employing Class A operation which can pass a less bastardized audio signal to the speakers.
What's not so great about them is that they are low power (you asked about 2 - 6 watts) so you need to mate them with the right speakers. From the responses above I don't believe the Proacs are the right speakers.
