In my opinion, there are no benefits, unless you like distortion and bloat. Not to mention that there are very few really great speakers that are affordable and will work well with SET amplification.
There are lots of high efficiency / high impedance designs available, many of which are very affordable. The problem is that most of them sound awful. SET systems are fun toys to play with, but I wouldn't recommend one for critical listening. It's just not reference quality stuff.
