Upgrade Speaker Cables: Replace stock cables with high-quality, oxygen-free copper for clearer, more detailed sound
One of the simplest yet most effective ways to enhance the sound quality of your Onkyo SR805 receiver is by upgrading the speaker cables. Stock cables often use lower-grade materials that can introduce distortion and limit the clarity of your audio. Replacing them with high-quality, oxygen-free copper (OFC) cables can significantly improve sound transmission, delivering a more detailed and dynamic listening experience. OFC cables reduce electrical resistance and minimize signal loss, ensuring that the full potential of your receiver and speakers is realized.
When selecting OFC cables, consider the gauge, typically measured in American Wire Gauge (AWG). For most home audio setups, 12- to 16-gauge cables are sufficient, with lower numbers indicating thicker cables and better conductivity. Thicker cables are particularly beneficial for longer runs, as they reduce resistance and maintain signal integrity. Additionally, look for cables with durable insulation and quality connectors to ensure a reliable connection. Brands like AudioQuest, Kimber Kable, and Blue Jeans Cable offer reputable options tailored to audiophile needs.
Upgrading speaker cables is a straightforward process, but attention to detail is key. Start by disconnecting your current cables from both the receiver and speakers. When installing the new OFC cables, ensure the polarity matches—typically marked with a stripe or label—to avoid phase issues that can muddy the sound. Secure connections tightly but avoid over-tightening, as this can damage terminals. After installation, allow the cables to "burn in" for 50–100 hours, as this can further refine the sound by settling the internal structure of the copper.
While the difference in sound quality may seem subtle at first, the impact of OFC cables becomes more apparent over time. You’ll notice improved clarity in vocals, tighter bass response, and a more expansive soundstage. This upgrade is particularly beneficial for the Onkyo SR805, a receiver known for its robust power delivery and detailed audio processing. By pairing it with high-quality cables, you’re not just improving the sound—you’re unlocking the full potential of your system.
Finally, consider this upgrade as part of a holistic approach to optimizing your audio setup. While speaker cables are a critical component, they work in tandem with other elements like room acoustics, speaker placement, and source quality. For those on a budget, upgrading cables offers a cost-effective way to achieve noticeable improvements without replacing your entire system. It’s a small change that yields big results, making it a must-try for any Onkyo SR805 owner seeking to elevate their listening experience.

Optimize Room Acoustics: Use rugs, curtains, or acoustic panels to reduce reflections and improve soundstaging
Hard surfaces like walls, floors, and ceilings reflect sound waves, creating echoes and muddling the clarity of your Onkyo SR805's audio. This phenomenon, known as sound reflection, distorts the intended soundstage, making instruments and vocals seem less distinct and spatially accurate. Imagine a symphony orchestra playing in a tiled bathroom – the reflections would blur the individual instruments, ruining the experience.
The Solution: Absorption is Key
To combat this, introduce sound-absorbing materials into your listening space. Think of these materials as sponges for sound waves, soaking up reflections and creating a more controlled acoustic environment. Rugs, thick curtains, and upholstered furniture are excellent starting points. For a more targeted approach, consider acoustic panels strategically placed on walls or ceilings. These panels come in various sizes, shapes, and colors, allowing you to integrate them seamlessly into your décor.
Placement Matters:
Don't just throw a rug down and call it a day. Aim to cover at least 25-30% of your floor space with rugs, focusing on areas directly in front of and around your speakers. For curtains, opt for floor-length, heavy fabrics that drape fully across windows. If using acoustic panels, target the first reflection points – the areas where sound waves bounce off walls and reach your listening position. These points are typically located on the side walls, slightly behind and to the sides of your speakers.
Experiment and Listen:
Improving room acoustics is an iterative process. Start with small changes, like adding a rug or repositioning furniture, and listen critically to the impact on soundstaging and clarity. Remember, the goal is to create a balanced acoustic environment where the Onkyo SR805 can shine, delivering a more immersive and accurate listening experience.

Speaker Placement: Position speakers correctly, following the equilateral triangle rule for optimal sound dispersion
Proper speaker placement is the cornerstone of achieving immersive sound from your Onkyo SR805 receiver. The equilateral triangle rule, a fundamental principle in acoustics, dictates that the distance between your listening position and each front speaker should be equal, forming an equilateral triangle. This arrangement ensures balanced sound dispersion, creating a cohesive and accurate soundstage. Imagine your ears as the apex of this triangle, with the left and right front speakers forming the base.
Steps to Achieve the Equilateral Triangle:
- Measure Twice, Position Once: Use a tape measure to determine the distance from your primary listening position (usually your favorite seat) to the desired speaker locations. Ensure these distances are identical for both front speakers.
- Angle for Accuracy: Tilt the speakers slightly inward, pointing towards the listening position. This focuses the sound directly at the listener, enhancing clarity and detail. Aim for a toe-in angle of around 10-15 degrees.
- Height Matters: Position the speakers at ear level when seated. This ensures the tweeters, responsible for high frequencies, are aligned with your ears for optimal high-frequency response.
- Center Channel Harmony: Place the center channel speaker directly above or below your television, centered with the screen. This speaker handles the majority of dialogue, so proper placement is crucial for clear and intelligible vocals.
Cautions and Considerations:
Avoid placing speakers too close to walls, as this can cause boomy bass and muddied sound. Ideally, maintain a distance of at least 6 inches from side walls and 12 inches from the rear wall. Room reflections can significantly impact sound quality. Experiment with speaker placement to minimize unwanted echoes and standing waves.
By adhering to the equilateral triangle rule and considering these additional tips, you can unlock the full potential of your Onkyo SR805 and create a truly immersive listening experience. Remember, speaker placement is an art as much as a science – don't be afraid to experiment and fine-tune until you achieve the perfect soundstage for your space.

Adjust Audio Settings: Fine-tune EQ, speaker levels, and Audyssey calibration for balanced, immersive audio
The Onkyo SR805's audio performance hinges on precise calibration, and its built-in Audyssey setup is your starting point. This automated system measures room acoustics and speaker placement, generating baseline EQ and level settings. However, Audyssey's one-size-fits-all approach often requires manual refinement for optimal results. Think of it as a foundation, not the finished product.
Audyssey's measurements can be influenced by factors like microphone placement and room reflections. For instance, a microphone positioned too close to a wall might lead to excessive bass compensation. After running Audyssey, critically listen to various content – movies, music, dialogue-heavy shows – and identify areas needing adjustment.
Fine-tuning begins with speaker levels. The SR805 allows individual adjustment for each channel. Use a sound pressure level (SPL) meter or a test tone generator (often included in Audyssey setup) to ensure all speakers output the same volume at the listening position. Aim for a balanced soundstage where no single speaker dominates. For example, if dialogue seems recessed, slightly increase the center channel level.
Adjusting the EQ is a more nuanced process. The SR805 offers parametric EQ controls, allowing you to target specific frequency ranges. Identify problem areas through listening: Muddy bass? Cut frequencies around 100-200 Hz. Harsh treble? Reduce 4-8 kHz. Subtle adjustments (1-3 dB) often yield the most natural results. Avoid drastic changes that create unnatural peaks or dips.
Remember, the goal is balance, not exaggeration. A well-calibrated system should disappear, allowing the content to take center stage. Regularly revisit your settings as room acoustics change with furniture rearrangement or seasonal humidity fluctuations. The SR805's flexibility allows for ongoing refinement, ensuring your audio experience remains immersive and engaging.
