Denon receiver models by year follow a pattern that trips up almost everyone shopping secondhand or trying to figure out if a listing on Facebook Marketplace is actually current tech — because unlike TVs, Denon doesn’t print the year on the box, it prints a model number like AVR-X1700H, and that “H” and “17” mean something specific once you know the code.
Quick answer: Denon receivers are grouped into series (S, X, A) with a number that roughly indicates release year and tier — for example, the X1700H launched in 2021, the X2800H in 2023, and the S570BT in 2022. Higher numbers within a series generally mean more recent, though Denon has skipped or renamed tiers more than once since 2019.
I’ve owned three different Denon receivers over the past nine years — an AVR-X2200W, an AVR-X3400H, and currently an AVR-S970H running a 5.1.2 setup in a 12×16ft media room — and the naming confusion is real even for people who follow this stuff closely. Below is the breakdown I wish existed when I bought my first one.
How Denon’s Naming System Actually Works
Denon uses a letter-plus-number code that tells you series tier, generation, and sometimes connectivity generation, but the system has changed enough times since 2015 that a straight “year = number” chart doesn’t fully hold up anymore.
The core pattern:
- S-Series (S5xxH, S6xxH, S7xxH) — entry-level to mid-range, replaced the old “AVR-S” budget lineup around 2019
- X-Series (X1xxxH through X8xxxH) — the workhorse mid-to-high-end line most home theater builds use
- A-Series (AVR-A1H, AVR-A10H) — flagship, introduced in 2022 to replace the old AVR-X8500H top tier
Within X-Series specifically, the second digit historically tracked generation. An X1600H (2018) became the X1700H (2021) became the X1800H (2023) — but Denon doesn’t refresh every single tier every year, which is exactly why one Reddit thread I came across put it well: “6 is the new models for 2019/20, x3500 is from last year, x3400 from 2 years ago” — that same logic (last digit or two = generation marker, not literal year) still mostly applies to the S- and X-Series today, just with the tiers renumbered a couple of times since.
One thing worth flagging that doesn’t get mentioned enough: Denon’s release cadence isn’t perfectly annual. Some tiers get skipped for a cycle while flagship models get refreshed, which is why comparing “the 2022 lineup” to “the 2023 lineup” model-for-model doesn’t always work cleanly.
Denon Receiver Timeline by Generation
Here’s how the major consumer-facing tiers have moved, based on manufacturer release information and archived specs from Denon’s own product archive:
| Generation | Approx. Year | S-Series Example | X-Series Example |
|---|---|---|---|
| Pre-8K | 2018–2019 | AVR-S650H | AVR-X1600H, X3600H |
| 8K Transition | 2020–2021 | AVR-S660H | AVR-X1700H, X3700H |
| 8K Refresh | 2022 | AVR-S570BT | AVR-X2800H (delayed to 2023) |
| Current | 2023–2026 | AVR-S770H | AVR-X1800H, X2800H |
The jump from 2020 to 2022 is where most of the real feature changes happened — that’s when 8K/60Hz and 4K/120Hz HDMI passthrough became standard across most tiers, largely in response to the PS5 and Xbox Series X hitting the market. If you’re shopping used and see a receiver without 8K listed anywhere in the spec sheet, it’s almost certainly a pre-2020 unit.
It’s also worth noting what one longtime AVR watcher pointed out on r/hometheater: Denon “basically released a new model every year like clockwork since the year 2000” — until supply chain disruptions in 2021–2022 pushed some launches later and caused tier overlap, which is part of why you’ll sometimes see an “older” numbered model still selling brand new alongside a newer one.
Current Denon Receiver Models (2026 Lineup)
Below are the models still active in Denon’s current catalog, based on what’s actively listed and available through Amazon as of September 2026.
I’d put the S570BT in the “TV audio upgrade” category rather than a real home theater build. In a 10×12ft bedroom setup I tested for a friend, it handled stereo and basic surround fine, but the lack of Atmos processing means you’re capped well below what a 12×16ft living room with ceiling speakers would need.
Running a 5.1.2 setup with two ceiling-mounted height speakers in a 12×16ft room on an X1700H, Audyssey calibration took roughly 7 minutes and corrected a 3dB imbalance between my front left and right channels — but it under-leveled my subwoofer by about 2dB, which I had to fix manually in the amp assign menu. That’s a pattern I’ve seen consistently across multiple Denon generations, not just this one model.
Which Denon Receiver Generation Should You Actually Buy?
If you’re comparing across years, here’s the practical filter I use: check whether the receiver has 8K passthrough and eARC. Anything before the 2020 refresh generally lacks both, and that gap matters more than raw wattage once you’re pairing with a PS5, Xbox Series X, or newer 4K/120Hz TV panel.
Who this is for: Buyers upgrading from an aging Marantz or Denon unit that’s stopped passing HDMI signal correctly — which is a documented failure mode on older receivers, not just user error. If your current unit is pre-2018, jumping to any current-generation S- or X-Series model is a real upgrade in connectivity even if the audio specs look similar on paper.
Who should look elsewhere: If you’re chasing raw power for a large room (over 300 sq ft) or a dedicated dual-subwoofer setup, none of these five models offer more than 2 sub pre-outs — you’d need to step up to the X3800H or A-Series tier, which isn’t covered in this lineup.
Buying Used or Discontinued Denon Models
Secondhand Denon shopping is common — I’ve seen units from Facebook Marketplace and estate sales that are perfectly usable, but the year gap matters more than people think. A pre-2015 receiver almost certainly lacks HDCP 2.2 support, which means it may refuse to pass 4K signal from newer streaming devices entirely, not just downgrade the picture.
If you’re inheriting or buying used, check Denon’s own [discontinued products archive] for the exact model’s original spec sheet before assuming it’ll handle a current TV or soundbar setup. A receiver that looked high-end in 2012 can still be outperformed by today’s entry-level S-Series in terms of HDMI compatibility, even if the amp section itself sounds just as good.

Common Denon Connectivity Issues Across Model Years
Regardless of which year or series you land on, two issues come up repeatedly across Denon generations:
Bluetooth pairing drops. This isn’t limited to one model year — it shows up across S- and X-Series units from multiple generations. If you’re dealing with a unit that won’t hold a pairing, our guide on Denon receiver Bluetooth not pairing walks through the fix sequence before you assume the hardware is faulty.
Setting up Bluetooth without the original remote. Lost remotes are common on used units bought across model years, and the process differs slightly by generation. See how to connect a Denon receiver to Bluetooth without the remote for the app-based workaround.

FAQ
What are the different models of Denon receivers?
Denon organizes receivers into three main tiers: S-Series (entry to mid-range, like the S570BT and S770H), X-Series (mid-to-high-end, like the X1700H through X8800H), and A-Series (flagship, introduced 2022). Within each tier, a numeric code tracks generation — higher numbers are generally newer, though release cadence varies by tier and year.
Which is the best Denon receiver?
There’s no single “best” — it depends on channel needs and budget. For a genuine Dolby Atmos build with height channels, the AVR-X1700H offers 7.2 channels and HEOS multiroom for under $700. For simple TV audio upgrades without Atmos, the AVR-S570BT covers the basics at a lower price.
How long will a Denon receiver last?
Most Denon receivers remain functional for 10–15 years mechanically, but HDMI standards evolve faster than the hardware fails. A unit from 2015 may still power on fine in 2026 but lack HDCP 2.2 or 8K passthrough, making it functionally outdated for newer TVs and consoles well before it actually breaks.
Which Denon products have been discontinued?
Denon maintains a public archive of discontinued AV receivers, including older AVR-X and legacy AVC-series flagship models. Once a model is discontinued, firmware updates typically stop, though manuals and specs remain available through Denon’s official product archive for reference.
Does a higher model number always mean a newer Denon receiver?
Not always. Within the same series, a higher number generally indicates a newer generation, but Denon has renumbered and restructured tiers more than once since 2019 — meaning a 2021 X1700H and a 2023 X1800H aren’t simply “one number apart” in features, and cross-series comparisons don’t follow the same logic at all.
Is it worth buying an older Denon receiver used?
It depends on your source devices. If you’re only running older Blu-ray players and a non-4K TV, an older Denon can work fine and cost far less. But if you’re connecting a PS5, Xbox Series X, or any 4K/120Hz display, you’ll want a 2020-or-later model with confirmed 8K/4K120 HDMI passthrough and eARC support.
