Looking to Upgrade my Speakers...Help! in 2-Channel Home Audio Posted October 12, 2010 Hogfan, I was in the same situation a few years back and went through a series of upgrades before sticking with Chorus II's. I used my Quartets for 2 channel listening for music and movies for over 10 years. Then I wanted the HT thing and got a new Yamaha receiver, an Academy and RS35 surrounds. That wasn't good enough so, I upgraded the Quartets' and Academy's xovers with Popbumper's upgrades. Still wanted more so I got Chorus II's to replace the Quartets as mains. And I've been happy with this setup of 4years now. The first time I hooked up the Chorus', my first thought was the music surrounded me. The sound stage of the Chorus' is so much bigger and forward compared to the Quartets.For an HT setup since you are already using 3 Quartets, you can keep the one as the center and move the other 2 as surrounds. Chorus II's will fit seemlessly in the setup.
