Bluetooth streaming


Opinions please!
Im streaming Spotify from my iPad to a rocketfish Bluetooth receiver,into a moon 100 d dac,into my preamp.Some music sounds pretty good while other songs just sound bad?I guess my question is ,would a better dac make a difference?Is it possible to clean up this source somewhat,or is this just a bad way to stream music?Thanks in advance!

Take a look at the Audioengine B1.  Have had it for almost a year and quite impressed.  
Milpai,
I pulled the trigger and ordered a Auris!Was a little cheaper than audioengine b1.Both had good reviews.Its got to be better than than rf box I'm using!My dac I have is a moon 100 d.Would you recommend using both the auris and the 100 d together,or only the auris?
@corvette01,
I forgot to mention that now-a-days the Auris bluMe comes with USB cable and charger. It was not the case when I originally purchased it.
Please let me know your thoughts on how the Auris sounds when you get yours and install it in the system. Will me more than eager to hear your comments, since there are not too many people on this forum who use this.
Milpai,
ill post something probably in a week or so,giving time to get it and listen.I definitely needed wireless for my upstairs system,so I'm happy to have options out there!

Milpai,
Just got BluMe today.Just a few songs in,sounds better than I expected!My system has depth to it not there before.So far I'm more than impressed!I would think it needs break in time,but out of the box it sounds great!My system sounds more expensive!Thanks for the tip!Even some of the bad songs I complained about sound better!
