Lo único que sé es:
Hola,
Pues creo que de las DDrum acústicas se ha hablado ya en el foro. En España creo que las distribuye (o distribuía) Madrid Musical, por lo menos teían un catálogo que se podía descargar de su web.
En la revista En Concierto también las han "analizado" o por lo menos hablado de ellas (
http://www.enconcierto.net).
Y en Ebay USA se ven bastantes.
He encontrado esto (en Wikipedia):
"ddrum produces drums that fall into one of several series, each following a motif of beginning with the letter "d" and grouped according to quality and materials used in construction. In addition ddrum is one of several manufacturers that offers customers the ability to customize their own kit from a number of criteria including shell dimensions, finish, and hardware options in what they call the "USA Custom Shop." Many of DDRUM shells are provided by Keller USA, which are identical to those used in higher priced drums made by other companies. DDRUM'S bold designs have exploded onto the market, and carved a solid niche with exceptional value and performance.

Snare Drums
Signature snare drums include Travis Smith's signature snare with custom drum wraps by Rockenwraps and Mike Marsh's signature stainless steel snare with a laser engraved finish
Other snare drums include the Hand Hammered Bronze snare, Birdseye Maple snare, and the solid steel "Grey Ghost" snare drum among many others
ddrum also produces deccabons, which are similar to octobans, except they are only six inches in diameter. They are available in clear acrylic or black fiberglass finishes. Sizes range from 6 inches deep to 24 inches deep."
Un saludo.
