If you want to experience the real HiFi sound, you should buy the Xls-encore and this speaker may the only bookshelf you'll ever need.
Pair it with a decent DAC and topping tp60 integrated amp, the performance is really good.
Rich in low end, the Mid is lush and sweet and the high is smooth.
Listening to acoustic song like by Madilyn bailey, boyceavenue and Kurt Hugo Schneider is really surreal, its like they are performing in front of you, not exaggerating, but that's the fact.
For me, I'm really into EDM, with a good mixed music, the sound is holographic. It can bring back the excitement of being there, at the festival of EDM
If you are into rock music, no problem. Xls-encore can handle the mess very well.
Jazz and Blues ah~ easy peasy to handle...
BUT
you can't achieve all that if:
1) You have no dedicated stand source. Isolation is the key.
2) Ur listening to a pirate, support original. The original is always better than the pirate, iTunes is always better than the .flac over the torrent site. That's what i've found over the years of downloading the illegal.
3) You don't have enough space to let the speaker breath.
CONs:
Can't think any at this price. If I want to pick one, Xls-Encore is not really suitable for current pop music..not all, but most of it. I think the sound engineering and arrangement is simply sucks. Not worth to be played by this gem..
The real pop is Michael Jackson, Womack and Womack, Toto etc...

You like toto as well? Recently, I found out their live album, "livefields" is extremely well mastered. You may give it a shot.
