WRAT (Wide Range Amplification Technology) was fine-tuned specifically for the A-9130 by Onkyo’s master technicians. Two 10,000 μF main audio capacitors were custom-made following exhaustive listening tests to realize a richness and dynamism that’s very easy to love. Make the A-9130 the heart of your home hi-fi and enjoy the musical refinement expected of a far more expensive component.
