For anyone building a home theater system, choosing the right AV receiver is crucial - it's literally the brain and heart of your setup. Today, we're comparing two popular options: the newer Onkyo TX-NR6100 ($519) and the compact Marantz NR1510 ($599). Let's dive into what makes each unique and who they're best for.
Before we compare specific models, let's talk about what matters in an AV receiver today. Think of an AV receiver as a smart command center - it processes your audio, switches between video sources, and powers your speakers. But modern receivers do so much more, from streaming music to handling gaming features.
The landscape has changed dramatically since 2019 when the Marantz was released. HDMI 2.1, 8K video, and more sophisticated gaming features have become important considerations. The Onkyo TX-NR6100, released in 2021, reflects these newer standards.
One of the biggest differences between these receivers is their power delivery and channel count. The Onkyo offers 7.2 channels at 100 watts per channel, while the Marantz provides 5.2 channels at 50 watts per channel. But what does this really mean for you?
In practical terms, the Onkyo's extra channels allow for either height speakers (for Dolby Atmos) or rear surround speakers. Having set up many home theaters, I can tell you that height channels make a noticeable difference in creating that immersive "sound bubble" effect - especially in scenes with overhead audio like helicopter flyovers or rainstorms.
The power difference is significant too. The Onkyo's 100 watts per channel versus the Marantz's 50 watts means it can drive speakers more efficiently in larger rooms. If your space is bigger than about 350 square feet, or you like listening at higher volumes, the Onkyo is definitely the better choice.
This is where we see the biggest technology gap between these receivers. The Onkyo TX-NR6100 supports:
The Marantz, being older, maxes out at 4K/60Hz. While this might seem fine for today, consider that the latest gaming consoles and high-end graphics cards already support 4K/120Hz. If you're building a system you want to last several years, the Onkyo's HDMI 2.1 features provide valuable future-proofing.
Both receivers handle basic surround sound formats well, but the Onkyo steps ahead with:
The Marantz NR1510 handles traditional 5.1 surround sound beautifully but can't process height channels for Dolby Atmos. In my experience setting up home theaters, Atmos makes a notable difference in creating a more immersive experience, especially in modern movies and games that are mixed for it.
Here's where the Marantz shines - it's half the height of standard AV receivers. If you're dealing with limited space or strict aesthetic requirements, this slim design could be a deciding factor. The build quality is excellent, with Marantz's signature curved faceplate looking particularly elegant.
The Onkyo follows a traditional design - it's bigger but includes more connectivity options and better ventilation for its more powerful amplifier section.
Both receivers offer modern streaming features, including:
The Onkyo adds Chromecast built-in and better multi-room capabilities through its Zone 2 HDMI output. This means you can send different audio/video sources to another room - great for larger homes.
Despite being newer and more feature-rich, the Onkyo TX-NR6100 is actually less expensive than the Marantz NR1510. Unless you specifically need the Marantz's compact form factor, the Onkyo offers better value with:

Choose the Marantz NR1510 if you:
For most users, the Onkyo TX-NR6100 is the clear choice. It offers significantly better features and performance at a lower price point. The only compelling reason to choose the Marantz is if you absolutely need its compact form factor.
Both receivers will serve well in their intended uses, but the Onkyo's more recent release date, better gaming features, and superior power handling make it the more future-proof choice. Its support for newer audio and video standards means it will likely stay relevant longer, making it an even better value in the long run.
Remember, the best receiver is the one that fits your specific needs, room size, and future plans. Consider your space, your current and future equipment, and how you plan to use your home theater when making your final decision.
