I've never done an internet review for any purchase.... ever.... until now.
My goal was to turn my entire home into musically-synced atmosphere from my full attic all the way down to the basement without having to run wires throughout the house or having to spend excessive money on wifi-linked and unpowerful speaker systems. I'd rather have control of my receivers and speakers specifically for each room and application. I had come across the Aperion Allaire Zona HAL system in a few forums and websites which all had very good things to say about it. Thought I'd give it a try. Only thing that scared me a little was the price and the uncertainty of them working as well as they sounded.
I first started with a sender and receiver pair about 1 year ago now and have slowly been building up the fleet! Initially I was blown away that they were so clear and never cut out; even through lathe and plaster walls and three hardwood floors. Was hooked and had to buy more! I currently have 2 senders and 4 receivers. I have a sender from zone 2 on my Yamaha receiver in the living room and one for the computer in the basement. My receiver has a built in amplifier that powers floor speakers in the dining room and a zone 2 stereo output which I connected a sender to. I have a receiver in the next room adjacent to the dining room, the kitchen. I have one upstairs in a bedroom, and one in the basement (which has also been in the attic at times).
They work well right next to your "typical" interference creating devices that I have had issues with in past with similar devices. I have one next to a microwave and two others right next to wireless routers on different levels of the house. Both senders work really well on different channels and all receivers connect well to either one with the press of a button. I never unplug any of them so they are all ready at any moment; I've never had any issues with that. I also have two roommates who have a ton of wireless electronics as well, never an issues with that either.
All speaker systems are synced extremely well. Between the systems with the Aperion receivers, those are spot on with each other. When comparing the direct analog speakers in the dining room with the speakers next to them in the kitchen, there is an extremely slight lag between these two systems. In fact I didn't really even notice it until maybe 2 months after having both playing. I have a picky ear and no one else has ever mentioned it to me. There are other devices out there that don't even come close to that, so I am extremely happy in that regard.
Never stop making them! Excellent product! (4/30/14)
