I bought the aud 2zs just after xmas. I was hooked up to a 2.1 speaker system, did not cut it. I was searching for new speakers and I decided on the creative 7.1. Paid $160cdn. I love em. Loud enough to made your ears hurt. No hiss, great sub, overall great sound. I looked at the z680's and was going to buy them but wanted to get all the benifits I could out of the sound card, movies still are only 5.1 but in the future maybe they will be 7.1. But I will be ready.
