"How can one get this smooth and refined high frequencies without severe treble roll off? "
For me it was a progression of things , of course the recording is the number one component .
I started by ditching metal tweeters in favor of soft dome or organic tweeters . As mentioned above ribbons will fall into this catagory as well .
I then ditched my SS CDP for a tube unit .
Then I ditched my SS amplification for tubed .
And finally finding a tubed int. amp with good top end extension .
It was a process of changes that taught me things along the way . This is not the only way but it is the way that works for me . And other things were accomplished along the way that increased my listening enjoyment .
While I believe that the smooth treble aspect can be accomplished with metal tweeters and SS components , it may come at a greater cost and may or may not give you the desired overall sound that pleases you .
For me it did not .
Good luck .
