Small Footprint (compact) amp to power speakers?


Hi all:

Looking for a small integrated amp to power a pair of Onix RS450 speakers.  Probably need 50W, at least.   I'll only be using it to stream to via Chromecast Audio.  

I've looked at the AudioEngine N22 but it doesn't have enough power. Even the NAD 3020 might not be enough.  Planning to spend under $500 used/new.  

Any suggestions?  I don't see many "compact" amps out there.  

Thanks.

3rd Bel Canto.   Their integrated amps actually kind of kick ass.  No power concerns, and they also serve as great preamps when you have cash to upgrade.  Keep your eyes open for a good price on a used C5.  
Parasound Zpre3 and Zamp3 makes for a very nice little system. Used would probably fall into your budget. 
Nuforce STA200. 80w. Got it new for $500 as a backup amp from AudioAdvisor. Nice little solid state push/pull. If needed u can get a $49 2 input switch box from Schitt. 
Can't find a Bel Canto under $900, unfortunately.  

The XTZ Edge A2-300 looks interesting. Not a lot of info about it out there. @riccitone61 have you heard it?

The Yamaha WXA-50 has a lot going for it.  But can't find any right now.  I like the Musiccast app. Sits vertical!

The Cyrus looks a little too chunky for the space.
