I wonder if Dave has any thoughts on this. I was planning on buying a Sierra-2 based 5.1 surround system, but now, I'm very intrigued about Atmos. Ceiling installation is more trouble than I'd like, so the Andrew Jones Elite Atmos 5.1.4 set sounds like it could get my money instead. I mean, the audio quality of the Elites won't be up to par with the Sierras, but I've heard they're pretty decent sounding, and at half the cost of the Sierras... hmm.
