Eagle's 14bit noteplayer is not very good imho.
The Deli 14bit noteplayer can run without AHI, it offer lot of options that you can't find in Eagle such as an auto volume boost which handle to listen correctly to XM, IT etc... you can even set a special config for a module.
Delitracker was more open than Eagle which explain that lot of people has developped some stuff for it. For e.g Jochen Hippel wrote his own Deliplayer and so you can play some of his ST format (Eagle can't do that)
Personally i like both Deli and Eagle... i even use the old Hippo to play .MOD
Hints: you can use Deli playlist with Eagle too.
