As home sizes seem to grow so too do the needs for speakers that can play loudly without a lot of power for greater dynamic range. Horns seem perfect so why aren't there more of them?

Has class D switching amplifiers come of age enough yet to seriously challenge the superior sound of class AB amplifiers?

Preamps are not exactly preamps. In this episode, Paul explains the difference between phono preamps and line preamps.

In this second part Lunch with Darren series, we talk about the abilities of the vacuum tube to counter the inherent distortions of the class D output stage.

When designing loudspeakers do designers take into account psychoacoustic impacts of the reproduced sound? And how?

On one hand we're told more capacitance the better, while on the other hand we're told there's no cap like no cap. What gives? How can both be true?

Why do so many loudspeakers feature multiple smaller woofers while it's known you need big woofers for bass?

PS Audio on occasion uses ICs but, for the most part, we rely upon the benefits of discrete circuitry. Would we consider a custom IC?

What combinations of equipment, room, and skill go into making a stereo image? Learn from the Audiophile Guru, Paul.

Infinity speakers once sported two tweeters, one in front and one in the rear. Why? This doesn't happen too much on other speakers.

Regenerators like PS Audio's Power Plant perfect AC power. Can one use it directly in a valve circuit?

Most preamplifiers have two outputs: a line out and a preamp out. What are the differences?

How does PS Audio deal with equipment sonic signatures? Do we purposefully use tubes and transistors to tailor the sound to some criteria?
