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?

So much of what we hear in audio cannot yet be measured. How then can engineers design circuitry around such unknowns and how do they know if they've succeeded or failed?

Vacuum tubes are the original amplification devices. How do they stack up against modern solid-state transistors, especially in audio systems? Paul gives us the real scoop.

Gold CDs, HDCD, XRCD. We read about all these different technologies and mediums yet CDs are CDs. Right? Paul explains the differences and why they matter.

Why do the ratings on the rear panel of amplifiers rarely match what their claimed output power ratings are? Is it possible to produce more watts at the speaker than the wall power can provide?

When PS Audio sets out to design then build and market new products is the first step in that process to gather together the competition? Do we try to keep up with the other manufacturers? The answers might surprise those unfamiliar with PS Audio.

The days of graphic equalizers and bass and treble controls on equipment have long since been replaced by better equipment that no longer needs these crutches. So, is there a place for them in today's world? Yes, and you might be surprised at what Paul has in mind.

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.

If the goal of high-performance audio is to do as little harm as possible, wouldn't it make sense to have as few components in the signal path as possible? Makes sense, but Paul explains why that just might be flawed logic.

Some preamp manufacturers insist their use of an inverted output is the right way to go and any products that do not invert are simply not as good. Is that true?

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?

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 re

What types of speakers crossovers are best to use? A 2-way or 3-way crossover? Paul tackles this intriguing question, one that has plagued speaker designers for decades.
