Well,I'm a sound lover ,have great ears that can identify sounds well.I just got 5 year old stereo speakers(which I stopped using a year ago

).I only use my wireless headphones,they have good bass and clear midrange and most importantly can work up to 100 meters without wires!!(I checked it).
Audio is Onboard.(Dont underestimate,Its Creative SB Audigy 2 SE with EAX1,2,3

)
Pasanlaksiri would be more than happy to tell you about these things.
And please post your RMS power of satellites and the woofer to get understanding of clear power of the system.
And if you use a Bose,Harmon Kardon,Blaupunkett,JBL,Altec Lansing just tell the name.We know we cant beat you.I know all of them well.And as a n advice,never ever get used to a Bose system.You will never ever feel satisfied with any other sound system after that.My friend have a one,We are now used to it and dont feel the Fat in the bass.And the richer smoother Transistor tweaked midrange is awesome in Bose.
