Adding the letter “D” to our Dreadnaught modular multi-channel amplifier model serves dual purposes. “D” is not only the 4th letter of the alphabet, it is also the amplifier class used in our new masterwork.
The Dreadnaught D brings the world-class performance of Theta Digital’s Prometheus monoblock amplifiers to users who require the finest multi-channel performance plus world-class flexibility.
