I haven't used the iLoud, so I can't help there, but I have a Soundfreaq SFQ-01 that sounds very good.

It had a lesser tablet I use for mp3, Youtube, and drum machine playback that is tethered (via headphone cable), which prompted me to run a Tab 3 and the Soundfreaq in parallel, so I can dispense w the cable and still mix or control playback from any position in the room.
The lack of output jacks led me to search for an alternative and I found quite a few. Some feed an analig stereo signal from Bluetooth input and run on batteries, others use a wallwart.
I haven't tested any of them yet, but at least two are widely available at Best Buy, the prices I remember are $20 and $50. Do a search and you should find many options that expand the possibilities.
