I am thinking about adding an amp (either a 2 or 4 channels) and Boston Pro 5.5. How is this compare to the Bose factory setup? I understand some people have change their non-bose to Boston pro with very satisfy result. Just wandering if I should do the same with Bose. Thanks

I'm torn between the Boston Pro's and MBquart referenze premium.... I A/B'd them in a shop for about an hour.... the Boston's seemed more flat, and the Quarts sounded a little more musical. I can't decide which ones I like better. I'd seriously try to listen to them against other decent brands before you decide on them.
