I am new in the forum and I am looking for a pair of bookshelves speakers to use with my sony receiver STR-DE697.

It is my understanding that the 7.1 receiver I got is a low end system and it does about 70 to 100 Watts (MAX) so I am seeking advice as what version should I get?

The new speakers I am looking for a primarily gonna be hooked up to my iPhone to listen to musics.

Any suggestions will be greatly appreciated.

Thanks.
