    • Good Value Works Great
Have two of these hooked up to 12 stereo zones in the house. Each zone is switchable from two inputs or a direct line in. Very flexible solution. I have 4 sonos zone players hooked up to two of these and it gives us 12 rooms of audio for a fraction of the cost. I am not an audiophile but they sound good to me! Update after 3 years: We have had these for three years now. Both units still work without any problems. FWIW, I have had these connected to a z-wave outlet for the past three years. This allows us to turn on the entire system (which is located in the attic) from the smartphone and control the music and the volume from the sonos. I have not even physically touched the units in more than two years - they just sit in the attic working fine and doing their job. Press the button, play the music, the z-wave automatically turns them off if we forget. I still have the 24 channels (12 rooms) divided into four zones, each with a Sonos "connect" (were called Z90s when I bought them). I would add more zones but the price of the connects make it a luxury I have just never been able to justify. If I were to do this today, I would probably put a set of airport express units on this (one can buy 7 express units for the price of two connects) and with iradio it offers much of the same functionality but would give you many more individually controlled zones. In any case, the Dayton units continue to work with no drama, no intervention, and no problems. Update after Five Years - okay I am upgrading to five stars: All good. No problems so far, they still work just as well as they did in 2011 when I first installed them. Admittedly, we do not run these a much as many people will, but still, five problem-free years. Props to Dayton (and Sonos, which is also problem-free after five years with regular software upgrades to keep the system and the app up to speed with the latest services). Five years of problem-free service deserves five stars. ... show more

    • Excellent Amp - Does what I need with Alexa as well
Here is how I set up the system. I set up 6 zones downstairs that were pre-wired before the house was completed. I wired directly to the speakers, not using a volume control in each zone. I bought 12 Alexa Dots and 6 3.5mm to RCA converters. Then I attached 6 of the dots to the RCA inputs for each zone on the amp and put each of them on mute. I also placed a an Alexa dot in each zone. Then I named each dot carefully. The dot in the Kitchen is named "Kitchen Dot" and the dot in the closet for that zone is named "Kitchen Speakers" This allowed me to tell any dot, anywhere in the home, "Alexa, play music on the Kitchen Speakers" and the dot in the closet streams the music to the speakers. You can also tell Alexa to "Lower the volume on Kitchen Speakers", so I avoided having to install or purchase volume controls in each zone. I am going to buy another unit for the upstairs zones now. Alexa also has Groups, you you can group multiple Zones together and say "Alexa, play music Downstairs" and it streams to several zones. I also have a group I call "upstairs intercom" so, I can stream "Reveille" in the morning to get the kids to head downstairs for breakfast. Update: I added the second amp for the upstairs zones and everything is working as planned. I have 24 Alexa dots running the two amps and the kids love that they have control over every room in the house and what music is playing on the ceiling speakers. I made a few groups, Like "Master Bedroom" group, that plays in Master bath, office and bedroom, in Alexa to allow multiple zones to play the same music as well. Also made a "Main" group that plays on all the common area speakers. Update: Alexa now allows me to make a dot a member of more than one group, so the office is now part of "All Downstairs Speakers" group, but not part of the "Downstairs" group (which is just the common areas). ... show more

    • Bought a replacement for a 10 year old identical unit the failed.
I was very happy with the original unit. I've used it to control two remote stereo zones in my house. The first unit stopped working after about 10 years of regular use. I looked at several cheaper options to replace the unit but all of them lacked the auto on/off feature which is critical for me. This feature automatically turns on the amp when an input source has a signal and then automatically returns to standby mode 15 minutes after all input sources lose their signal. ... show more

    • Works well, but bridged mode is problematic.
I bought this amp for my home, which had ceiling speakers installed by a previous owner. I only needed to power 6 speakers so I tried using bridged mode for more power, and presumably better sound quality. The wiring for bridged mode is a little complex, so I quadruple checked that I had wired everything correctly. The result was that in some songs, backing vocals or guitar solos would be nearly inaudible. I spoke with someone at Dayton Audio support, and they had no clue why that would happen. I returned to standard mode, no longer using the bridging feature, and everything sounds normal. Can't comment too much on sound quality. I'm playing a Chromecast Audio as a source, and the ceiling speakers are average, so it's not an audiophile rig. Sounds fine. I do wish it cost a hundred bucks less or so, but it does weigh a lot, so probably loaded with well made components. I'm not aware of any competing amps like this from other companies, at least not priced the same or lower. ... show more
