This is the best around.Before taking this I checked out sony, aiwa and kenwood.People say a lot about sony.But didnt get the feeling was looking for.The effects seemed to be distant and lacked the power for the price.The features that it gave were same as the one the panasonic gave.This model comes at a price tag which is above the rest in the same category but has more power and features packed into it.The sound is life like and does not irritate even at higher volume levels.The effetcs are crystal clear and the bass is deep and impressive.But this one has the best effects and power in this category.check it out buddies.
