I have used the Quintet and thought it made a noticable improvement in the sound of my system. If you can find one, buy a used Quintessence....these usually run $450 to $500 on the used market and it is noticably better than the Quintet. Also, getting a Soloist in-wall is a good start. They usually run $140 or so used and work well too.
I currently run a combination of the Soloist Premier and the Power Plant Premier with very good results.
Happy Listening
