I've had the 14" New Beats for over 30 years, and they're still awesome. When I saw Kenny Aronoff do a demo on the 15's, thought I'd give it a try. Its going to be my main hats from now on. The 14's sound a little muted next to the 15's. Good service from Sam Ash, think I got the last 15's, because they sold out (Probably the promotion they were running ?, great deal).
