"The European oriented "classical" players tend not to be able to approximate the lilt of a good Irish fiddler no matter how much technique they have at their disposal."

One can also say that the 'traditional style' players can't keep correct time when they play Classical Music too. One can also say that they are hopeless at playing 'ensemble' as they are all 'soloists'.

"lilt of a good Irish fiddler"

Depends how thier 'training and experience' was...
