The Creative Inspire 5.1 5700 has served me well, but now it's time to move to a proper home cinema set. My idea is to first buy the AV receiver (obviously) and a pack of speakers later (you know, my wallet is not endless), so I was wondering if the 5700 speakers and sub can be used while saving for the new speakers. Given that many AV receivers only accept 8 ohm speakers, this is an important issue, because I can't find that exact data for the 5700. Any experiences on this? Many thanks.
