Pioneer VSX-323-K Sound Amplifiers

good product, but some settings are not obvious.

top customer service, the product arrived perfectly packaged and very well protected. Unfortunately, the product is particularly "dirty" and very dusty inside the device (probably from its original owner) and visible through the ventilation "holes" suggesting poor storage or use outside manufacturers' standards (dust / humidity). As the product does not inspire confidence, I prefer to withdraw my order before using it.
