Query: Crackle, pop and wavy sound!

I completely agree with some of the prior negative reviews. This system does snap, crackle and pop (and it has nothing to do with other electronics) unless you are talking about anything else plugged in. With significant treble in the music you will hear the system pop, so most rock is immediately out. Gaming wise, I haven't had any problem with the midi reproduction.Overall, however, there is a wavy output which I find rather annoying. I am not an audiophile by any stretch; but I do notice a surge in music as I listen to my iPods playback. This may have to do with the AC current from the bulky adapter. Why not supply a direct current?? It pretty much steps down your 110VAC to 12 VAC. That is why some say it is not too portable. Sitting on the desktop, it looks pretty good, I think. Hope this helps
