I've nuVero 3 boxes and am still excited about it. The A100 Nupro I have now bought because I wanted to party boxes a pair that will sound for a small Hofparty. The delivery was fast and the speakers came well packaged within the agreed delivery time. The speaker then I have connected to my Macbook, first with the supplied USB cable. It worked the same, then I have also supplied optical cable connected via a Toslinkadapter to the Macbook, works just fine. The sound of the "small" speaker is outstanding, which is great fun and it's amazing how clear and juicy sounds sind..Nubert precisely. The subwoofer is not absolutely necessary, the bass is amazing. Can not imagine listening to these speakers on the desk to me that suck so away from the table. I have now connected to the TV and am absolutely satisfied and enthusiastic. Of course, 570 euros are for a pair of powered speakers a lot of money, but good quality now has its price, and I think these speakers are their price absolutely worth it. By the way, the Hofparty was sounded fine with the boxes and the neighbors also had what it ;-)
