A:AnswerHello Stan,
The remote and the mic do come with the TXNR5100 when purchased as New. Unless if the item is sold as an OpenBox item then the accessories would have to be purchased separately.
Thank you
Onkyo
A:AnswerThis receiver does not have speaker switches. With some configuration, you can reassign the hig surround speakers as a second zone instead of being surround.
A:AnswerThere are pre-installed music services on this unit. These services are the only thing that can be streamed through the ethernet (or wi-fi) connection.
