Query: Sony: not what it used to be, alas...

Bought this DVD player; it arrived defective - a loud buzzing on the audio channels. Sony tech support confirmed it's a defect, sent it back. Amazon was great, shipped a replacement immediately. The second one had the same defect. We unplugged a player from another room - no buzzing. What are the odds of it happening twice? Not high...unless it's a defect in the design or manufacturing line. My real problem is with Sony - they offered to replace, but wouldn't promise new (it may be refurbished) and wouldn't offer expidited shipping even on the second defective unit - weeks of waiting. So much for their commitment to quality! I returned #2 to Amazon and bought Toshiba. Works great.
