Home Theater Receiver Onkyo TX-NR5008

Circuit Vector Linear Shaping (VLSC)

Conventional D/A conversion methods reduce digital pulse noise at the conversion stage but cannot eliminate it completely.

WRAT technology offers three advantages

Low current feedback design to enjoy ultra-precise sound even during peaks.

Closed-loop mass circuits to appreciate the highest sound volumes without distortion.

High Instantaneous Current response to fully appreciate the sonic impact of movie soundtracks.

What the press says

The TX-NR5008 is a masterpiece that completely won us over with its features, its status as the ultimate home theater amplifier, its musical rendering on CD, S.A.CD and DVD-A, and its superb video processing.
