Overview

The Sony STR-AN1000 is a 7.2-channel AV receiver released in 2023, featuring HDMI 2.1 support for 8K/60Hz and 4K/120Hz video passthrough, Dolby Atmos and DTS:X compatibility for 3D audio processing, 360 Reality Audio support, and Digital Cinema Auto Calibration IX for automatic room correction. Priced around 598 USD, it represents Sony’s ambitious return to the AV receiver market after an extended absence.

Scientific Validity

\[\Large \text{0.6}\]

The STR-AN1000 specifies 165W (6Ω, 1kHz, 1ch) output power with published THD measurements of 0.09% (20-20kHz, 2ch drive). However, detailed S/N ratio and comprehensive frequency response data remain unpublished, limiting comparison against transparency level criteria (THD ≤0.01%, S/N ≥105dB). The incorporated 32-bit DAC, improved power supply circuitry, and enhanced analog output filter circuit using JFET and op-amp technologies may contribute to sonic improvements, yet verification through detailed measurement data is insufficient for definitive assessment.

Technology Level

\[\Large \text{0.4}\]

The product employs fundamentally industry-standard design approaches with limited proprietary technology integration. While incorporating Sony’s 360 Spatial Sound Mapping technology for pseudo-surround effects and D.C.A.C. IX automatic room correction system, these technical approaches demonstrate similarities to implementations found in competing products. The adoption of 32-bit DAC and power supply improvements merit recognition, though the THD measurement of 0.09% represents average performance by contemporary standards, lacking significant technical distinction or advancement beyond industry norms.

Cost-Performance

\[\Large \text{0.7}\]

The STR-AN1000’s retail price of 598 USD compares against the Denon AVR-X1700H (80W/8Ω, 0.08% THD, 399 USD refurbished) which offers equivalent 7.2-channel, 8K/4K HDMI 2.1 support, and Dolby Atmos/DTS:X compatibility. CP = 399 USD ÷ 598 USD = 0.67 demonstrates cost-performance disadvantage. The Denon AVR-X1700H provides equivalent functionality with superior THD performance (0.08% vs 0.09%) while being approximately 200 USD less expensive in refurbished form.

Reliability & Support

\[\Large \text{0.6}\]

Sony products generally demonstrate high reliability with comprehensive global support infrastructure. The STR-AN1000 provides standard warranty coverage and firmware update support. However, as Sony’s product following extended absence from the AV receiver market, the sustained support and update track record in specialized home theater applications may be less established compared to dedicated manufacturers like Denon, Marantz, and Yamaha.

Rationality of Design Philosophy

\[\Large \text{0.6}\]

The STR-AN1000’s design philosophy demonstrates rationality through HDMI 2.1 compatibility and Dolby Atmos/DTS:X support addressing contemporary requirements. The integration of 360 Spatial Sound Mapping technology provides practical value for users lacking physical ceiling speakers. The 2023 design incorporates modern gaming features (VRR, ALLM) and 4K/120Hz support as standard equipment, accurately addressing contemporary user needs. The implementation of 8K/4K-capable HDMI 2.1 inputs and 360 Reality Audio support demonstrates forward-thinking design considerations. The necessity for specialized audio equipment existence is recognized.

Advice

The STR-AN1000 delivers fundamental 7.2-channel AV receiver functionality with 8K/4K support and major audio format compatibility at the 598 USD price point, though cost-performance evaluation reveals limitations. The Denon AVR-X1700H (399 USD refurbished, 699 USD new) offers equivalent functionality with superior THD performance (0.08% vs 0.09%), making it a more compelling value proposition. However, the Sony product provides modern gaming features (VRR, ALLM) and 360 Spatial Sound Mapping technology that may appeal to specific user requirements. As Sony’s AV receiver market re-entry product, it reliably delivers fundamental functionality, though superior alternatives exist at comparable or lower price points.
