Are you sure that the speakers are failing with rock? I'd suggest getting good speakers that detail well with good recordings and verify they can blast to your satisfaction. If more bass is desired augment with a sub or select another speaker. IMO most rock music is badly recorded and can make a good system sound plain. No surprising as in a concert you have a pile of 2 inch tweeters and 12 inch woofers. We are often playing it back on better stuff then it was initially played on. Guess it depends on what the user wants. ROck the house sort of indicates the desire to cause damage but in sonic control?. IF thats the case maybe some paradigm studio 100's, b&w CM9's and likely a bunch more. Another option would be to go to the music store and drop $800 on a amp combo unit. THe new ones take mp3 input and will cause damage in line with the origional performance. just a thought.
