The Echo Dot easily connects to any Bluetooth speaker or, via wire, to any audio. It sounds great. Your article seems to imply that this is not the case. With the ongoing improvements (recently Alexa can now understand context, like Google Home), it's sure to stand up against any competitor. It is a phenomenal device.
