Kyo9999Why would you use a inexpensive amplifier to power a multi-driver loudspeaker with lots of crossover components all of which are parasitic parts? Your review therefore is without merit. Light? What does that mean? This is an amplifier for desktop speakers, it prefers a 4ohm load as all class-D amplifiers are dependent on the resistive loading provided by the loudspeakers. Again your review lacks any merit as a result. There is such a thing as equipment matching which is essential to get the most out of any audio device. I hope you don't get an allowance for a refund as you clearly have zero idea of what you are doing.
