I found the use of an Equitech 2Q for isolation plus an MIT Oracle AC power cable made a nice difference. (I had them prior to picking up my near the end of the line 205-- a little pricey relative to the Oppo; but it shows the 205 has potential beyond what you get from standard ac power, by quite a bit.). I felt lucky to get my Oppo and continue to be highly pleased with DVD's and Bluray's and streaming from my cable provider. Going to move up to a Samsung 4K and kind of excited about that as well :)
