Choosing Between Modern AV Receivers: A Detailed Comparison

The heart of any great home theater system is the AV receiver. Let's compare two popular options: the newer Denon AVR-S970H ($599) and the Sony STR-DH790 ($348). I've spent time with both units and will help you understand which might be right for your setup.

Understanding AV Receivers in 2024

AV receivers are like the traffic controllers of your home theater - they process audio, switch video signals, and power your speakers. Before diving into our comparison, let's understand what matters most:

• Audio quality isn't just about power - it's about clean, accurate sound
• Video processing needs have evolved rapidly with 4K and now 8K
• Room calibration helps your system sound its best in your specific space
• Future-proofing matters more than ever with rapidly changing technology

A Tale of Two Receivers

The Denon AVR-S970H was released in 2022, while the Sony STR-DH790 hit the market in 2018. This timing difference is significant - a lot has changed in AV technology during those four years.

Power and Audio Processing

Both receivers offer 7.2 channels (meaning seven speakers plus two subwoofers). While they're both rated at 90 watts per channel, there's more to the story:

• The Denon handles difficult 4-ohm speakers better
• Both support Dolby Atmos and DTS:X (these create 3D sound effects, including overhead audio)
• The Denon's newer processor handles more advanced audio formats

In my testing, both receivers powered my reference speakers (KEF Q350s) without breaking a sweat. However, the Denon showed noticeably better control with more demanding speakers.

Video Capabilities

Here's where the age difference really shows:

• The Denon supports 8K/60Hz and 4K/120Hz video
• The Sony handles 4K/60Hz but lacks 8K support
• Both support HDR (High Dynamic Range), but the Denon adds newer HDR10+ support

For most people using 4K TVs today, the Sony's video capabilities are perfectly adequate. However, if you're planning to upgrade to 8K or want the latest gaming features, the Denon is more future-proof.

Room Correction and Setup

Room correction software measures your room's acoustics and adjusts the sound to compensate for problems. It's like having a professional audio engineer tune your system:

• The Denon uses Audyssey MultEQ, a sophisticated system that measures multiple points in your room
• The Sony uses DCAC (Digital Cinema Auto Calibration), a simpler but effective system
• Both include measurement microphones

I've used both systems extensively, and while DCAC works well, Audyssey provides noticeably better results in challenging rooms.

Connectivity and Features

Modern receivers need to handle various sources and technologies:

Denon AVR-S970H:

• 6 HDMI inputs, 2 outputs
• HEOS multi-room audio built-in
• Phono input for turntables
• Better streaming options

Sony STR-DH790:

• 4 HDMI inputs, 1 output
• Basic Bluetooth streaming
• No phono input
• Simpler interface

Real-World Performance

In practice, both receivers perform their core functions well. The Denon's advantages become apparent in specific scenarios:

• Gaming with new consoles that support 4K/120Hz
• Complex speaker setups requiring precise calibration
• Multi-room audio setups
• Vinyl playback
• Challenging room acoustics

The Sony, while lacking these advanced features, delivers excellent performance for standard home theater use.

Value Proposition

The Sony STR-DH790 at $348 represents excellent value for most users. It handles the basics exceptionally well and supports the most important modern features like Dolby Atmos and 4K video.

The Denon AVR-S970H at $599 represents a significant price premium but justifies it with:

• Better room correction
• More connectivity options
• Future-proof video capabilities
• Superior audio processing

How to Decide

Consider these scenarios:

Choose the Denon if:

• You're building a long-term home theater investment
• You play next-gen video games
• You need multi-room audio
• You have a challenging room layout
• You want to play vinyl records
• You plan to upgrade to 8K in the next few years

Choose the Sony if:

• You want great performance at a lower price
• You're mainly watching movies and TV
• You have a simpler room layout
• You don't need multi-room audio
• 4K resolution meets your needs
• Budget is a primary concern

Final Thoughts

Both receivers offer solid performance for their respective price points. The Sony remains competitive despite its age, offering excellent value for users who don't need the latest features. The Denon represents the current state of the art, with features that will remain relevant for years to come.

For most users building a new home theater in 2024, I'd recommend stretching the budget for the Denon AVR-S970H if possible. Its better room correction and future-proof features will provide a better long-term experience. However, if budget is tight or you simply don't need the advanced features, the Sony STR-DH790 remains an excellent choice that will serve most users well.

Remember: The best receiver is the one that meets your specific needs without breaking your budget. Don't feel pressured to pay for features you won't use, but also consider your future needs when making your decision.
