I have an Oppo 203 DVD player with the power supply upgrade by Oppo Mod.com. In additional to a higher grade transformer and higher grade capacitors, the new power board has a removable fuse. I changed out the HiFi fuse supplied with the mod to a Synergistic Research Blue fuse and yes indeed there was improvement in both audio and video performance.
I am a big supporter of these third generation audio fuses like the Synergistic Research Blue fuses. Trying them is certainly a lot cheaper (return postage is about $3.00) than many other mod-tweeks, and one also gets to overcome the fear of opening up their equipment for inspection. Yes I was indeed nervous when I also replaced the fuse in the Pass Lab amp. But I am glad I did. The SR Blue fuse allows the amp to sound better than the original Little Fuse did. Paul McGowan who is president of PS Audio has stated at his web site that audio grade fuses make a difference. I agree.
The PS Audio.com site has several good sources of information without a lot of hyperbole.
