have the instrument after thorough reserche here on Amazon purchases. I was skeptical because of the low performance. after as almost always fast delivery and first tests I'm fully convinced of the plant. You can easily keep arrive with stronger a lot or most of them even outdo loose. Crystal clear music in which the bass is not neglected. it no 1000 watt 5.1. conditioning is, is clear, but as I said it sounds much bigger than it is! a strong buy recommendation !!
