Personally I think the 5.4's sound great with most music but NOT and I repeat, not heavy metal or most hard rock. Maybe because they are so revealing and a lot of the harder type music is not recorded very well but when I brought mine home it really changed the way I listen to music. If I need my head banging fix I just go to the garage system. Make sure you audition them with your kind of music not the stuff they play in the audio salons before you buy them.
Dynaudio or B&W
I have a pair of B&W 703s and am thinking about going to a pair of Dynaudios. I purchased a pair of Focus 140s for my other system and just love them. I have been tossing around the idea of the 220s or the X36s. I may go Contour as well but the hang-up is cash. It could happen though. I am using a Jolida JD-1000RC which is plenty for the 703s and I would suspect plenty for the Dyns as well. I listen to everything from classical to metal. Any opinions welcome.
Thanks.
