Summary: Purchased this to upgrade an 85 WATT Onkyo and after all the rave reviews I was pretty jacked up to try it out. I had noticed a number of people complaining about quality control issues and the left and/or right channels dying or having static issues. Sadly the latter all turned out to be true. Initially the receiver powered up and frankly I was a bit disappointed with the sound quality - I really thought my old Onkyo sounded way better with considerably less power.
Summary: Purchased hk3490 from and discovered a firmware bug after later adding the ipod doc. This was confirmed by a FAQ on the manufacturer website. They required an RMA of the unit at my expense to get it fixed. Shipping charges totaled $78. Also, their FAQ has a dead link to request support. The real support form elsewhere on their site doesn't render correctly in firefox.
Summary: I purchased a factory refurbished HK 3490 for my vacation house at the beach. When it arrived in May 2013, I attached speakers and tried to use it. The unit immediately displayed the message "Voltage Protect, Check DSP" and stopped operating. This happened several times. I call HK service and the technician suggested that I had a short in a speaker wire and explained how to test. I performed the test, replaced a speaker wire and the unit performed for two days.
