I disagree. I don't like 5.1 until you spend some bux on it. A good 5.1 system will shine... But I've found a good 2-channel system can sound great, too.
For instance, I'm running a HD cable box > almarro A205A SET amp > almarro M2A speakers in my home office. I recently had ProAc Tablette Ref 8's in that room (less expensive). I have an LCD TV in the middle and sometimes watch movies when my wife is using the big rig for something else. This system consistently surprises me with the vast sonic expanse it delivers, far bettering the enjoyment I got out of my old HD box > Denon 1802 > 5 B&W DM302's with a Velodyne sub. Both rigs cost about the same if you consider the ProAc's.
So yes, I'd much rather have a small tube amp and 2 Dreamcatchers than a low-cost 5.1 setup. Every time. And it will sound much better on music, too. And your upgrade path, should you so choose to add 5.1, will lead you to a much better rig in the end. Some people say it's about priorities, that 2-channel cannot do well with movies. I simply disagree.
Now when you're talking serious bux, you have many options that allow you to tie a 2-channel and 5.1 in a high-quality rig.
