Description
Hifi Rose RSA280 : Integrated Amplifier
The RA280 is an integrated amplifier that inherits the innovative technologies used in RA180. Enjoy pure natural sound as close to the original sound as you can get with the RA280: a near-perfect sound that transcends the boundaries between digital and analogue technologies with excellent linearity achieved through strong power damping and short dead time. The RA280 offers a special listening experience that lets you feel the true essence of music.
