Play-Fi 4+

I have enjoyed the app and my McIntosh speakers. I’m into it about a week now and have had minor learning difficulties and I stress minor.. I’m not a technical guy and this is my first go and this type of technology. It is different and takes a little to get use to but not frustrating. My only disappointment is that it will not play 100% of my purchases on iTunes. I am happy that I can play the satellite radio as well as local radio stations. Definitely more options than I was aware.
I do recommend this and the speakers. I have two RS100 speakers and a self powered subwoofer. The sound is amazing for the investment. I didn’t even unpack my NAD system. Giving that to the less fortunate.. the kids.. 🤪

I have 2 McIntosh RS100 speakers as a Sterio pair, and a Martin Logan Crescendo X powered speaker, as well as 3 McIntosh MB50 streaming units in 3 different stereo systems in my house. The Play-Fi app controls each speaker/system flawlessly and is operated from my Apple phone and separate Apple iPod Touch units which I bought for each room/system in my house as they make great remote controls, so that I do not have to use my Apple phone if I don’t have it in my pocket. Very convenient. Play-Fi has periodic updates for the app which continues to improve the app on a regular basis. I am and continue to be Very pleased with these high quality products/speakers which depend on the Play-Fi app for reliable control. Play-Fi app also has helpful suggestions and tips to help you in the set up process. I anticipate buying new products that use Play-Fi app control in the future as various high end audio companies hopefully will continue to offer new products to the market that incorporates the Play-Fi app.

Abandoned by Definitive Speakers after spending thousand of dollars on their speakers. Will never purchase their speakers ever again. With the newest update, now when some of the single speakers volume level is changed (lowered or raised), it also changes the master volume level. It’s impossible to make a correction (raise or lower volume to balance a single speaker or stereo speakers) as it also changes the master volume. The new look and feel of the app has had a vast improvement, but the update of the software to all my 9 Definitive Speakers took over 3 hours. It was a constant struggle having to place some the speakers off line, back online, take some off of stereo, erased all my original saved streaming setup, try to recognize speakers that weren’t recognized, had 2 different names speakers that responded to the same test speaker, unplugged numerous speakers and plugged back in to reset, etc. if you have an issue, just start from scratch and that might help. But now everything works ok… until the next update!
