Curbed my upgradeitis with a purchase of the 340s, which are now my mains, with the 170s as my surrounds. SVS 20-39PCi will be upgraded in the future, after my maggies get sold. I could not be happier that I started with the 340s. On HT, the soundstage with 340s is spectacular. Of all the different surround configs Ive had, this one is the best. Dynamic range, intelligible dialogue over the action, and beautiful dispersion in stereo. A real pleasure. Great integration with the SVS. Who needs to go to the movies?
