Thanks for all the feedback! Yes, it is about $1000 total (except the sub, which I have), and no, right now I don't have much more to invest, but I may in the future, which is why I was considering buying a better amp. Still, I guess it works out the same, whether you upgrade you amp later or your speakers, you still have the old gear to deal with. Hmmm... So difficlut to choose, and yet still fun...
