Just for an example, I used to have old Cerwin Vega D7's run off of Sherwood seperates. These Cerwins, while not superb speakers, were tons better than the Cerwins you can get today. I purchased them new in 1985. I still have them. Each speaker has a 12" woofer, two 5" mids, and a horn tweeter.
I now have MB Quart towers. Each speaker has two 6.5" mids, and a titanium tweeter. I am using one NHT 12" powered sub. There is no comparison. None. Zilch. Nada. Everyone of my friends, while not an audio nut like myself, are blown away. When I take the grills off of my Quarts, they look around back to see where the rest of the speakers are. I know you look at what I am telling you and say, this guy is an idiot, but I am just trying to help. I am sure your system is loud, and it would make any ones ears bleed. But, if quality sound reproduction is what you aspire to have, you are headed in the wrong direction.
