Hello Antoine, on the Jplay forum, Josef wrote : "UltraStream uses UDP protocol which does not guarantee delivery – other engines use TCP which does (='lost packets' are automatically re-sent)". Before reading this, I did not understand why I heard sometimes a very small crakle/pop but no error was detected by the Thesycon spy tool (everything was set to minimum : minimum latency under 'buffer settings' in the control panel tool, directlink under jplay settings). When I tried ultrabuffer = 10, I had more crackles/pops, but how to be sure to have no crackle at all with a greater value of ultrabuffer ? When I used only one computer, I tried the other Jplay engines, and each time I had a crackle, it was detected by the spy tool. With UltraStream, a packet can be lost, but there is no way to detect it. So I don't use UltraStream anymore. On my system, only River and Beach are possible to keep minimum latency under 'buffer settings', with XStream, errors are detected (I can have XtreamSize = 5000, the maximum possible). I did not hear a loss in sound quality with those engines, could not determine which one sounds "best". Of course, other users with another system could have a different experience.
