What Audio System Powers Your Home Theater?

FusionJunky asks: "My cohorts and I at The GeekPad are working to develop our home theatre into something a little more robust. We picked up a 36" Sony Television and a respectable DVD Player...now we're ready to tackle audio. We've noticed we have this optical out capability from the DVD player, and a bunch of other new fangled plugs back there, and we were wondering what the Slashdot community uses for home theatre audio. We'd like to keep it under $1500." I'd be interested in what you all feel is the best system for the buck, from your choices in tuners to speakers.
