Loudspeakers first

The Audiophiles Guide ·

2025/06/25

Forget the source, forget the amp—start with the speakers. This episode makes the case for putting loudspeakers first when building a high-end system, drawing from the principles in The Audiophile’s Guide. Why are speakers the most flawed—and most important—part of the chain? How do their limitations shape everything downstream? If you’ve ever wondered where to put your money first, this is a clear, no-nonsense look at why it all begins with the box (or the panel). The Audiophile’s Guide publ...

The Phantom Center Channel

The Audiophiles Guide ·

2025/06/24

A centered vocal with no center speaker? That’s the magic of the phantom center channel. In this episode of The Audiophile’s Guide, we dig into how two speakers can convincingly create a stable, lifelike center image—when the setup is right. From precise speaker placement to room symmetry and listener position, every detail matters. When it locks in, the illusion is powerful: a voice suspended in space, as real as if someone were standing there. The Audiophile’s Guide publishes daily. Want to...

Acoustic nulls in the room

The Audiophiles Guide ·

2025/06/22

In this episode of The Audiophile’s Guide, hosts Robert and Sandra tackle the challenge of acoustic nulls—those frustrating dead zones where bass seems to vanish. Caused by wave cancellations from room boundaries, nulls can rob music of weight and impact. Learn how to identify them, why speaker and listener placement matters so much, and what can (and can’t) be fixed with treatment or EQ. Solving nulls is key to unlocking your system’s full low-frequency potential. The Audiophile’s Guide publ...

Understanding the RIAA curve

The Audiophiles Guide ·

2025/06/20

Vinyl isn’t just about the warmth of analog—it’s also about precision, especially when it comes to the RIAA curve. In this episode of The Audiophile’s Guide, we explore why records are cut and played back with intentional equalization, and how the RIAA curve preserves fidelity, lowers noise, and restores musical balance. Discover how your phono stage decodes this curve, and why getting it right is essential for hearing vinyl the way it was meant to sound. The Audiophile’s Guide publishes dail...

The source or the loudspeaker?

The Audiophiles Guide ·

2025/06/17

Send us a text Is it better to invest in the source or the loudspeakers? In this episode of The Audiophile’s Guide, we take on one of the oldest debates in high-end audio. Speakers shape the final sound, but the source defines what gets there in the first place. Explore how each influences detail, dynamics, tone, and emotional connection—and why the best systems treat them both as critical voices in the same performance. The answer isn’t either/or—it’s how they work together. The Audiophile’s...
