"...if you've bought into the Duette, you've bought into the Wilson way. The WATCH Dog offers a fantastic upgrade for that speaker, delivering increased bandwidth, transparency, texture, tonal colour and scale to what is already a wonderfully musical speaker. But the real gain is best expressed in musical rather than hi-fi terms."
