McIntosh Cast Connect vs GeeFlow

Use the McIntosh Cast Connect app to enable Google Cast functionality to our MSA5500 Streaming Integrated Amplifier. If you plan to utilize one of the other built-in streaming technologies in the MSA5500 instead of Google Cast, installing this app is not necessary.
