Yamaha 9.2-Channel Network AV Receiver: RX-V2085 $800, AVENTAGE RX-A3080 $1250

Sound quality finessed. The Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity preamplification, anti-vibration technology and independent pure power supplies. This model has fully discrete power amplifiers that help minimize distortion. It also adopts pure independent power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog circuitry. The anti-vibration heat sinks are designed to suppress vibration from transistors and sound pressure. Independent power supplies for the DACs are designed to further eliminate noise on certain models. Down to every detail, this AV receiver is designed with full emphasis on the highest possible sound quality.
