When it comes to features, because of the Wi-Fi issues I've experienced, the M3 seems unable to access music streaming services at this time but, hopefully, this can be overcome in the future by fixing the existing apps

If you can live with just Bluetooth and 'wired' as way to access it, the M3 would be the best you can possibly get in this price range.(4

The M4 I could tell would be easily portable; I hadn't realized until I received it that the M3 is so portable too

And the M3 looks good

The M3 sounds so good, I forgive all the issues I've experienced with the Wi-Fi, resulting in a limited set of features vs. what I expected or what some competition offers

WOW - this far exceeded my expectations!I have a network of various Airport Express connected speakers, a WIFI connected Zeppelin Air, and now this GGMM M3
