Query: Very poor unit

I purchased this unit and after about 4 months time it malfunctioned and produced no audio. Because the unit was under warranty, I sent it to be repaired by one of Onkyo's authorized repair facilities. They took 3 months to get it back to me and when I reconnected the unit it only lasted ONE day before it broke again for the same reason--no audio.Onkyo's customer service and management does not care about providing any type of customer service and I would not recommend purchasing any Onkyo products. I trashed this unit and purchased a Yamaha to replace it.If buying any Onkyo product buyer beware!!!
