My friend bought a 5.0 Jamo system for his Yamaha and likes it but I haven't been over to hear them yet. Both are respectible brands. If you have to buy without listening, check user reviews, I personally would prefer the set with larger woofers although no guarantee of better sound, I'd also lean toward more efficiency. I'm too lazy to read the entire thread again but if you post links to the speakers I'll take a look to see if there's anything between the two that might make any difference. Or, model numbers and I will check.
