Amps with bluetooth vs wi-fi

[Nitin K]

Hi fm's,

I was curious as to know why certain amps use bluetooth as against wi-fi for streaming via a phone/tablet etc in an era of good internet bandwidth. In my limited knowledge, wi-fi seems to have a broader bandwidth hence the quality would be better due to lesser compression. Besides considering even the superior connectivity with wi-fi .
Please do let me know your thoughts. Thank you.
