I am upgrading my system and am looking at the Z9 or the upcoming 59TXi. I currently have 2xNHT VT2s and 3xVS2s with a NHT sub. I just purchased an SA3 to biamp the VT2s and now need to pick up 2 more speakers for 6 & 7 in the 7.1 system. I am leaning towards the Mirage Omnisats and wondered if I can use the micros or do I need the full blown Omnisats? While money is not a huge issue, the Omnisats are $500 and the stands are $300. Is this overkill for those last 2 speakers? What about 8 & 9 if I go with the Z9? Any better suggestions? Thanks.
