Denon AVR-S650H Review

The Denon AVR-S650H sits in a sweet spot that a lot of home theater newcomers eventually find themselves eyeing: capable enough to run a real surround setup, priced low enough that it doesn't feel like a commitment you'll regret. But how does it hold up once you actually live with it?

Who This Is For

The S650H is clearly aimed at the budget-to-mid-range buyer building their first serious surround setup — or someone upgrading from a decade-old single-zone receiver. It handles 5.1 and basic Atmos configurations without asking you to take out a second mortgage. One Reddit user described their journey moving from an older Pioneer receiver to the Denon S650H, calling it a clear step up — though they eventually moved on to a higher-end Onkyo unit when they wanted full Atmos features. That's actually a useful data point: this receiver is a solid launchpad, not necessarily a forever piece.

HEOS: Clever Feature, but Requires Patience

One of the more interesting real-world use cases that surfaced in discussions was HEOS multi-room audio. A user wanted to stream their turntable — connected directly to the S650H — to a home office in another room, without buying dedicated HEOS speakers. The setup they outlined (using a HEOS Link into a PRE-OUT) is technically feasible, and the HEOS iPhone app handles zone management. You can configure scenarios like "living room only" or "both rooms," and the system attempts to compensate for network delay between the analog and streamed outputs.

That said, HEOS is not exactly known for being effortless to configure. If you're the type who reads manuals for fun, you'll be fine. If you just want it to work out of the box, expect a learning curve.

Feature Set at This Price

For a receiver in this tier, the S650H punches reasonably hard. You get Dolby Atmos and DTS:X support (important caveat: at this price point, you're working with a limited number of amplified channels, so full 5.1.2 Atmos is possible but don't expect the headroom of a flagship unit), HEOS built-in for multi-room audio, Audyssey room correction, and a solid HDMI input count for the price. It supports 4K passthrough, which matters if you're pairing it with a modern TV.

The Audyssey setup is one of those features that sounds boring until you actually run it and hear your room-corrected audio versus uncorrected — it's a genuine improvement for most real-world rooms.

The Entry-Level Ceiling

Here's the honest truth about the S650H: it's a gateway drug. The Reddit discussions around this receiver consistently show a pattern — users buy it, enjoy it, and then start wanting more channels or better Atmos performance. Moving from 5.1 to 5.1.4 is a common next step, and the S650H's amplifier channel count will eventually become the bottleneck if you chase that upgrade path.

For a modest 5.1 setup in a small to medium room? Genuinely excellent value. For someone already dreaming of 7.1.4 Atmos with in-ceiling speakers, you might want to stretch the budget now rather than upgrade in 18 months.

Practical Buyer Tips

• Run Audyssey calibration before you make any judgments about the sound — uncalibrated, most rooms will sound unbalanced
• If you plan to use HEOS for multi-room audio with an analog source (like a turntable), budget for a HEOS Link device in the secondary room
• The S650H handles 4K/HDR passthrough but verify HDMI firmware is current before assuming all your sources will play nice
• Pair it with efficient speakers — this isn't a high-wattage amp, and efficient speakers (like Klipsch) will get more out of it than power-hungry alternatives

Frequently Asked Questions

Q: Does the Denon AVR-S650H support Dolby Atmos?

A: Yes, the S650H supports both Dolby Atmos and DTS:X. However, given its channel count, you're best suited for a 5.1.2 Atmos setup rather than a full 5.1.4 configuration.

Q: Can I use HEOS on the AVR-S650H to stream audio to another room?

A: Yes. The S650H has HEOS built in, allowing multi-room audio. To send audio to a room without HEOS speakers, you'd need a HEOS Link device connected to your secondary audio system. Zone configuration is managed via the HEOS app.

Q: Is the Denon AVR-S650H good for a first home theater setup?

A: It's one of the stronger options at its price point for a 5.1 starter setup. It includes Audyssey room correction, HEOS networking, and 4K passthrough — features typically found on pricier units.

Q: What speakers work best with the AVR-S650H?

A: Efficient speakers with higher sensitivity ratings (88dB and above) will get the best performance from this receiver's amplifier. Brands like Klipsch are frequently paired with entry-level Denon receivers for this reason.

Q: Will I outgrow the AVR-S650H quickly?

A: If you're planning to stay at 5.1 or 5.1.2 Atmos, probably not for a while. But if your goal is eventually a 7.1.4 setup with full Atmos height channels, you'll hit the S650H's channel limits and want to upgrade sooner than later.

At its price, the Denon AVR-S650H is a smart buy for anyone building their first real home theater. It does enough right — HEOS, Atmos support, Audyssey calibration — that you won't feel like you compromised. Just go in knowing it's a starting point, not a destination.
