Home theater systems are getting more modular, and Marantz is leaning into that shift with its latest release: the AV 30 preamplifier and AMP 30 power amplifier. Designed for users who want more flexibility than a traditional AVR can offer, these two components give you more control over how you build or expand your setup, whether you're upgrading your living room system or starting from scratch in a dedicated theater space.
At $4,000 each, the AV 30 and AMP 30 join Marantz’s growing lineup of separates, positioned just below the flagship AV 10 / AMP 10 and the mid-tier AV 20 / AMP 20. The goal is to offer high-performance processing and amplification without forcing you into a one-size-fits-all box. Instead, you can mix and match components based on your needs, your room, and your plans for future upgrades.
“The new AV 30 and AMP 30 perfectly represent Marantz’s unwavering commitment to excellence. With their outstanding performance, elegant design and supreme versatility, the two models are exceptional additions to Marantz’s world-class home theater portfolio,” said Lyle Smith, President of Sound United at HARMAN.
The idea behind the AV 30 and AMP 30 is pretty straightforward: split up the roles of audio processing and amplification so you can customize your setup more precisely. Instead of relying on a big receiver that does everything, you get a preamp/processor (AV 30) to handle your video and audio sources, and a separate amplifier (AMP 30) to power your speakers.
That approach gives you more control over your system and more room to grow. You can start with just one amp, then add more power or channels as your needs evolve. And since both units share a clean, modern look (including Marantz’s signature circular display and soft side lighting), they’ll match visually with the rest of your gear.
Inside the AV 30, there’s a lot going on. Marantz has equipped it with a dual-core SHARC DSP from Analog Devices and paired that with 32-bit DACs. Together, they handle all the latest surround sound formats: Dolby Atmos, DTS:X, IMAX Enhanced, and Auro-3D.
To make sure those formats sound good in your specific room, the AV 30 comes with Audyssey MultEQ XT32. That’s a room calibration system that adjusts speaker distance, level, and other factors based on microphone measurements. If you want to take things further, the AV 30 also supports Dirac Live, Dirac Bass Control, and Dirac’s new Active Room Treatment (ART), though those require additional licenses.
As for connectivity, the AV 30 can output 11.4 channels via RCA or XLR, making it suitable for full surround systems with multiple subwoofers. You also get a user-friendly interface, flexible input options, and support for custom install features.
All seven HDMI inputs on the AV 30 support 8K/60Hz and 4K/120Hz passthrough, so you’re covered for the latest video sources and gaming consoles. There’s also a high-res on-screen menu system to help walk you through setup.
For streaming, the AV 30 uses Marantz’s HEOS platform. That means you can stream music from services like Spotify, TIDAL, and Qobuz, and integrate with other HEOS-enabled speakers in your home. The unit also supports AirPlay 2, Bluetooth, and is Roon Ready, so you’ve got plenty of options for getting audio in.
The AMP 30 is a 6-channel power amplifier that delivers 200 watts per channel into 8 ohms (when two channels are driven). But it doesn’t stop there. You can also bridge pairs of channels for up to 400 watts per channel in a 3-channel configuration, or bi-amp your front speakers if your setup supports it.
That makes the AMP 30 a good fit for a variety of situations. You could use one to power the front half of your theater, and another for the surrounds. Or you could drop it into an existing Marantz system—like the CINEMA 30 AVR—to beef up power for the front speakers. It also plays nicely with Marantz’s larger amps like the AMP 10 or AMP 20 if you’re building a big system.
Like the AV 30, the AMP 30 supports both balanced (XLR) and unbalanced (RCA) connections, so you can pair it with a wide range of gear.
One of the best things about the AV 30 and AMP 30 is how easily they slot into different system configurations. If you want to build an 11-channel system, you could use two AMP 30s. Or you might combine the AV 30 with an AMP 10 or AMP 20 for even more channels and output.
You’re not locked into one path—whether you're upgrading an AVR, starting from scratch, or building out a multi-room setup, the AV 30 and AMP 30 let you tailor the system to your space.
Marantz’s new AV 30 and AMP 30 sit as the most accessible entry point in the brand’s current “separates” ladder, below the AV 20 / AMP 20 and the flagship AV 10 / AMP 10. The easiest way to understand the lineup is by channel count and system scale: the AV 30 is an 11.4-channel processor, the AV 20 steps up to 13.4 channels, and the AV 10 goes further with 15.4-channel processing.
In real-world terms, that’s the difference between building a common 7.1.4-style immersive setup (AV 30), moving up to larger layouts like 9.1.4 (AV 20), or planning a more speaker-heavy room where extra channels matter (AV 10).
What’s interesting is that the AV 30 doesn’t look “stripped down” in the ways people usually worry about. It still targets modern sources with seven HDMI inputs that support 8K/60 and 4K/120, and it keeps the same general approach to room setup: Audyssey MultEQ XT32 is included, and Dirac Live options (including Bass Control and ART) are available as paid upgrades, similar to how the AV 20 and AV 10 families are positioned. So for many buyers, the decision won’t come down to HDMI or basic feature support as much as whether your speaker plan needs 11 channels of processing or something higher.
On the amplification side, the differences are even clearer. AMP 30 is a 6-channel amp rated at 200 watts per channel (with the option to bridge channels for up to three 400-watt outputs), while AMP 20 expands to 12 channels and AMP 10 goes to 16 channels for systems that need more powered speakers from a single chassis.
Pricing tracks that hierarchy, too: AV 30 and AMP 30 land at $4,000 each, compared to $6,000 each for the AV 20 / AMP 20 pair and $8,000 each for the AV 10 / AMP 10. Put simply, AV 30/AMP 30 are aimed at people who want the separates approach and modern processing, but don’t need the extra channels—and cost, that come with Marantz’s higher-tier stacks.
The Marantz AV 30 and AMP 30 are all about flexibility. They’re designed for people who want to separate their audio processing and amplification, whether for better system control, higher performance, or future expandability. With support for immersive audio formats, room correction, high-bandwidth video, and multiple speaker configurations, these components are made to grow with your system, not box you in.
If you’ve been thinking about making the jump to separates, this pair might be a practical starting point that doesn’t require going all the way to Marantz’s flagship models.
Both the AV 30 and AMP 30 are available now, each priced at $4,000 (also €4,000 or £3,500).
