Denon S540BT vs Denon AVR-X1700H Review

Two Denon receivers, two very different jobs. The S540BT is a compact stereo Bluetooth receiver aimed at simple, space-friendly setups. The AVR-X1700H is a full-featured 7.2-channel AV receiver built for home theater — Dolby Atmos, HDMI 2.1, the works. Comparing them head-to-head might seem unfair, but people do genuinely find themselves choosing between "keep it simple" and "go full home theater," and that's exactly the decision this review is here to help you make.

Denon S540BT

What It's Good At

The S540BT is designed for people who want decent sound without the complexity. Bluetooth connectivity, a compact form factor, and support for basic stereo listening make it an easy fit for a bedroom, small apartment, or desktop setup. It's approachable for someone who just wants to pair a phone and hit play — no HDMI matrix to configure, no Audyssey room correction to run, no 7.2 channel speaker placement to obsess over.

For casual music listening — streaming from a phone, connecting a CD player, or running a simple two-speaker setup — it delivers what you need without asking much in return. The form factor alone is a genuine selling point if space is tight.

Where It Falls Short

The limitations become obvious fast if your ambitions grow. There's no HDMI passthrough, no Dolby Atmos or DTS:X support, no surround sound capability. One Reddit user described literally upgrading from the S540BT to the AVR-X1700H specifically because they wanted to add a center channel speaker — something the S540BT simply cannot support. Once you want more than a stereo pair, you've hit a wall.

It's also worth being honest about the audio quality ceiling. At its price point, it's a capable little unit, but it's not an audiophile-grade amplifier. If pure stereo sound quality is your obsession, dedicated stereo integrated amps — even modestly priced ones — will often outperform it.

Denon AVR-X1700H

What It's Good At

The AVR-X1700H is what people mean when they say "entry-level home theater done right." It supports 7.2 channels of surround sound, Dolby Atmos, DTS:X, HDMI 2.1 with 4K/120Hz passthrough, and includes Audyssey room correction to help you dial in your speaker setup. For anyone building or upgrading a home theater in 2024-2025, this is the receiver the community consistently points to as the sensible starting point.

Reddit's home theater community has been recommending it regularly, and it surfaced at Costco for as low as $299.99 during late 2024 sales — a price point that made it an almost no-brainer at that tier. At $400 standard pricing, it's still considered solid value. One user described it as "perfectly acceptable and still widely used for entry level theaters," which is about as honest an endorsement as you'll find from a crowd that loves to argue about gear.

The HDMI 2.1 support is practically important. If you have a Nintendo Switch 2 (or any modern gaming console), you need an AVR that can handle passthrough without stripping features — the X1700H handles that without issue, unlike older budget receivers that choke on HDR or 120Hz signals.

Where It Falls Short

It's an entry-level receiver, and it shows in some areas. The power output is modest — fine for most living rooms, but if you're running inefficient speakers in a large space, you may feel the limits. It also lacks some of the advanced features found on higher-tier Denon models, like more sophisticated room correction or higher-end DAC components.

Setup complexity is real. For someone coming from a simple Bluetooth speaker or a stereo-only system, configuring an AVR with multiple speakers, HDMI sources, and room correction can feel overwhelming at first. That said, this is a universal AVR learning curve, not unique to the X1700H.

One Reddit thread specifically noted that users sometimes wonder whether to place the unit in an entertainment cabinet — ventilation matters with AVRs, and they run warm. Not a dealbreaker, but worth planning for.

Verdict: Which One Should You Buy?

The honest answer is that these two products barely compete — they serve fundamentally different buyers. But if you're on the fence about whether you need "simple" or "full setup," here's the clear breakdown:

Buy the S540BT if: You want a tidy, compact unit for a bedroom or small space. You only need stereo speakers. Your TV has its own HDMI switching and you just want something to drive a pair of bookshelf speakers with Bluetooth convenience. You're not planning to add a center channel, surrounds, or a proper subwoofer.

Buy the AVR-X1700H if: You want a home theater — even a modest one. You game on a modern console and need 4K/120Hz passthrough. You want Dolby Atmos. You're starting with a stereo pair now but plan to add speakers later (as the Reddit upgrade story from S540BT to X1700H illustrates perfectly). You want one device to manage all your HDMI sources, audio processing, and speaker amplification.

The real trap is buying the S540BT thinking it'll grow with you — it won't. If there's any chance you'll want surround sound within the next couple of years, skip straight to the X1700H. The community upgrade path is well-documented, and nobody who made the jump to the X1700H seemed to regret it.

Frequently Asked Questions

Q: Is the Denon AVR-X1700H worth buying in 2025?

A: Yes, particularly if you can catch it on sale. It appeared at Costco for $299.99 during late 2024 promotions, and even at its standard $400 price point, it remains one of the more recommended entry-level home theater receivers by the Reddit home theater community.

Q: Can the Denon S540BT support surround sound or a center channel?

A: No. The S540BT is a stereo-only receiver and cannot support surround sound configurations. Users who wanted to add a center channel speaker have had to upgrade to a full AVR like the X1700H.

Q: Does the AVR-X1700H support 4K/120Hz for gaming?

A: Yes. The X1700H includes HDMI 2.1 with 4K/120Hz passthrough, making it compatible with modern gaming consoles including the Nintendo Switch 2 and current-gen PlayStation and Xbox hardware.

Q: Is the Denon S540BT good for music listening?

A: For casual listening in a small space, yes. It handles Bluetooth streaming and stereo speaker setups adequately. However, dedicated stereo integrated amplifiers at a similar or slightly higher price point will generally outperform it for serious music listening.

Q: How does the AVR-X1700H compare to the older Onkyo entry-level receivers?

A: The X1700H offers meaningful upgrades over older budget AVRs like the Onkyo HT-R393, including HDR passthrough, 4K/120Hz support, Dolby Atmos, and more modern HDMI standards — exactly the features that make it a worthwhile upgrade for current setups.
