Hi there. I'm looking to build out an audio system. I have bought a Denon 2106 receiver and am now looking at speakers. However, I need to build this system up gradually over a year or so to ease the $$ impact. So, I'm considering two options. The first involves buying a nice pair of front mains and going two channel for awhile. (Use here will be 30:70 HT/audio) I have listened to the totems (Hawk, Arrow, Sttaf and Forest) and love them. So, I'm thinking maybe a pair of Sttafs to start (I would like to step up to the hawk, but its 6 ohm impedance scares me. I know my amp could drive them, but the spec sheet lists a 0.7% THD at 1kHz into 6 ohms, and I figure if you are going to drop a couple grand on speakers that much noise is unacceptable). The idea here is that I would add back/center and sub at a later date. The other option is basicaly the reverse... Go grab a 5 channel solution now, and later upgrade the front sides. I'd use the extra pair for either 7.1 (though my room is a bit small for that) or for a second zone audio. Also, along the impedance line... I have heard good things about the Dreamcatchers (also from totem), but again, the speakers are all low impedance. Does impedance matter as much (for noise more than whether they will work at all) in a setup with a powered sub? I would think that if you switched all frequencies under say 80 Hz to the sub the strain on the amp driving low impedance mains would be lessened. If I choose to shy away from low impedance speakers, can anyone recommend a decent 8 ohm 5 channel set? Any comments or feedback would be appriciated. Thanks!
