sofa_king: focus on the question. I am not concerned about other systems . Question was re: Niles and Nuvo. I realize Nuvo Concerto is MSRP 8K. They are discounting now for 3-4K - that is a fact. Do some online rsrch and you'll see. Thus for around a 14 keypad system, Nuvo is being priced lower. The Niles is being spec'd with Polk 8" speakers and the Nuvo with Episode 8" speakers. Speakers are roughly $300/pair and I need around 15 pairs. (Retail might be closer to 500).
Anyhow, I am going with Nuvo. Looks as if they are comparable and I like the Nuvo Keypads more since they appear to provide more info.

If you have an opinion on the best 8" ceiling speakers, let me know.

Thanks for your help.
