Major manufacturers often make several virtually identical lines of appliances including musical instrument and charge more for the one with the manufacturer's name on it. Don't be misleading by names when you look for a good-quality sounds system or any musical instrument. If you are looking for a sound mixer, look for numark x6 mixer because it is guaranteed that it has a good sound quality. Names don't necessarily guarantee sounds quality. The best way to determine a good sounds quality is to read customers testimonials about the product.
