What Actually Matters
1. Speaker Placement
The listening triangle. Distance from walls. Toe-in angle. Height from the floor. Every inch changes what you hear. This isn't subtle. It's the difference between a system that images clearly and one that doesn't.
2. The Listening Position
Where you sit defines the sound more than almost anything else. Too close to the back wall and bass becomes muddy. Off-center and the stereo image collapses. The "sweet spot" isn't a metaphor—it's geometry.
3. Room Treatment
Hard surfaces reflect. Soft surfaces absorb. Empty rooms ring. Overstuffed rooms sound dead. Balance matters. A few strategically placed panels do more than random foam everywhere.
4. System Integration
Mismatched impedance. Ground loops. Poor cable routing near power lines. Digital noise. These aren't esoteric issues—they're real problems with real solutions. Most "bad sound" is just bad integration.
5. The Chain Matters
The weakest link defines the system. A great DAC into a cheap preamp. High-end speakers on a receiver with poor room correction. One compromised component colors everything downstream.
