I use the Treo's and are moving up to the Quatro as soon as I can sell my Treo's. Misnomer, Vandersteen are best for rock. Can't be further from the truth actually. It's design allows it to not smear transients and that means 'clean' sound. Yes, it's very dynamic, however I love it best when it shows how correct it gets the timber, pace and rhythm. To me if a speaker is THAT good, it will give you a honest presentation and that means is will probably get all music correct. The best part is that you will be able to dial it into your room, so you can basically put the speakers where you want them and not where they have to be. That's one reason I want the Quatro CT. Many feel this speaker is their money speaker. For the price it gives you the best bang for the buck. Which dealer will you use?
