You’ve said in the past that measurements cannot tell us how electronics sound. Please explain why this is true and how specifically, THD isn’t a good indicator of sound quality.

Here’s a problem Paul has struggled with for nearly 40 years and still, to this day, he only has succeeded in solving a partial bit of this terribly difficult problem. Find out his thoughts on why stereo systems do not replicate the sound of live music and what is being done to solve that problem.

Polarity controls are rare on equipment and this viewer wonders why and Paul does his best to explain what a polarity (or phase) switch is and why it’s not trivial to add it to a piece of equipment.

If subwoofers were able to roll off the bottom end of the main loudspeaker, wouldn’t there be advantages like greater clarity, lower distortion, and less power spent? And, if that’s true, why don’t manufacturers offer such filters with subwoofers?

Subwoofers help our systems come alive by bringing the realism associated with live events into our homes and supplementing where our main speakers fall short. But they only go down so low. Is it possible to go lower than what a conventional subwoofer does? Enter the Rotary Sub.

We’re all on some type of budget and this question revolves around how best to spend those dollars when building a high-performance audio system. From the under $1,000 killer system to the $100,000 killer setup, choosing how and when to spend money is an art.

Pace, rhythm, and Timing are what PRAT means but how do you achieve that when designing an amplifier? Is it possible to control the PRAT of an amp that reviewers refer to?

What do audiophiles think about soundbars designed for under the television sets? Their claims of high performance and sonic superiority are certainly wild enough to suggest they are likely God’s gift to mankind. But, what’s the truth?

The three pillars of reproduced music are the recording, storage, and reproduction. Which of these pillars can be improved upon? Paul suggests the recordings themselves could be.

When PS Audio voices its amplifiers for bass it is performed on the IRSV which itself has a separately amplified woofer section. How can you accurately voice bass on a system that has its own bass amplification system?
