I purchased 3 Legrand Nuvo P5200 Whole home audio amplifiers (each gives 3 zones at 200W for each zone!!) with 12 pairs of speakers worth thousands to cover 12 zones in my newly renovated house a year ago from Audio installations aka electromarket. I took advise from Danny Burt from the project inception stage. This is a niche area and very less people around there in the market who can suggest before buying. Many sell the expensive (Sonos types ) and dealer controlled systems like Control4/Crestron which are simply unnecessary. My house is simply transformed with music everywhere, out of all the smart things i have the most beloved system is the whole home audio. Thanks to electro market for the advise and excellent customer service. All delivered next day and easy returns too.
