From an audio perspective only, what is better for distribution for 21 zones? Doing a Triad 16 and Triad 8 (stacked properly) or doing Binary Moip audio senders for each audio zone? Not worried so much about the audio quality, just looking for which will be most dependable, work the smoothest in the C4 app, and play continuously without crashing. My wife and I like to keep either Pandora or Sirius XM playing softly in the various zones (probably 5-6 zones) nearly 24 hours a day. It's like "mall music" in the house to us and when the music is off, we feel like something is missing, lol.
