Stronger magnetic circuit for the driver unit: The AH-D7000’s stronger magnetic power provides robust drive that is capable of producing a dynamic, high-resolution sound.(11.4% boost in magnetic power: DENON comparison)
Piano finished real wood mahogany housing, superior acoustic effects: The same type of high-grade natural mahogany used to make guitars has been used for the AH-D7000's housing. This has been done because of the superior acoustic characteristics of such wood. To ensure the highest-quality sound, DENON engineers have analyzed a full range of elements from the shape of the housing and its thickness to the final finishing used on pianos.
Microfiber diaphragm, to reproduce delicate nuances.
Acoustic Optimiser, to achieve ideal acoustic characteristics.
Cloth-wrapped cable with high-purity (99.99999% OFC) 7N-OFC wire and equal length for left and right channels, to optimize sound quality.
Cable with tangle-free, twisting-resistant Elastomer sheath: The cable covering is made of Elastomer to guard against touch noise and other types of sound distortion caused by vibration. This tangle-free material also makes the cable easy to use.
ø6.3mm (0.25 inch) Aluminum plug matching DENON’s high-end models.
Gold plated connector.
