I tend to do alot of research on all companies I intend to buy from. It is stated on their website so I would assume a claim like that would have to be true. I've been playing drums for 28 years now, and I play professionally both live and recording sessions. I can remember when Tama was the #1 drum and everybody had to have one!! ( thanks to drummers such as Neil Peart who played them, namely Superstar series with Birch shells, and one set which was Maple) Lars Ulrich from Metallica was a huge boost for them as well. On a professional level, I would imagine that claim may be true. I'm not 100% positive, just going based on what I've read.
