A BIAS: Right in the middle

How boring if you’re biased right in the middle eh?  You don’t lean to the left or the right, you’re just middle of the road for everything – as if you don’t actually have an opinion.  Well, in audio amplifier designs that’s exactly what you want – a totally neutral middle-of-the-road stance when it comes […]

Aha! moments

Paul McGowan writes ….. Few things in life are as satisfying as an aha! moment: the solving of a tough problem, the solution to a puzzle, getting your stereo system dialed in. One of the more common aha! moments for people is when they try easing up on speaker toe in. Most speakers don’t want […]

HIDDEN TRAPS

Paul McGowan writes: I have always found it curious when someone says to me “I am 100% vinyl in my system. No use for digital audio whatsoever.” Or, “I never listen to vinyl, too dated, sounds bad.” Or, “I have sold all my CD’s and gone just to SACD.” It’s curious because these extremes many […]

WHITE NOISE: The outside edge

Reader Tom Richard writes “As a long-time bass player, I’ve always used cymbals to judge music reproduction. The worst systems give you white noise; the best present so much information. Can you hear the difference between standard wood tip drumsticks and nylon-tipped? The amazing differences between cymbals struck near their edge, in the middle and […]

PS AUDIO: Modulators

  In our ongoing series on class D amps and listener fatigue I made the point (hopefully) that the input stage is a critical path element in the chain – because if you can’t get this part right then everything else that follows only contributes to making things worse. It’s like putting bad gas in […]

Don’t confuse me with facts!

Paul McGowan writes: I have now officially been accused of “defending digital” in the face of overwhelming evidence that analog sounds better.  How dare I? Let me suggest that there are three things I will passionately defend in audio – and digital isn’t one of them. The truth.  We may not like to look at […]

Dopamine anyone?

Paul McGowan: My friend Robert sent me a link to a great article on how music affects the brain in the New York Times.  It’s well worth the read should you be as interested in the subject as I am. What it shows is the same mechanisms at work we use for figuring out all […]

But I got to thinking about how anyone could have nominated such tripe for best anything and it occurred to me this happens a lot, even in our industry.

I am mindlessly working out at the gym on the elliptical trainer, watching the many TV’s and there it appeared. Out of nowhere. I nearly fell off the machine. It was an ad for The Wolf Of Wall Street, proclaiming it’s been nominated for Best Picture. This in the face of actually having watched the […]

PS AUDIO: Do you treat the room or the system? The cause or the effect? The illness or the symptoms?

Our quick response to these questions would be to treat the cause rather than the symptoms – we’ve seen many examples of this in our lives and intuitively the answer seems obvious – but does it apply to our rooms? Should we be running digital correction, processors, equalizers to force our systems to work within […]

Horn loudspeakers: “The next track was a female vocalist. I was equally stunned because this sounded so unnatural as to be unnerving.”

A lot of people love the sound of horns.  I am not one of them.I do love some of the qualities they present: high efficiency, terrific dynamic range, dynamic contrasts and great transient speed. I do not love their tonal characteristics.  Cup your hands around your mouth and speak – this is what horns do […]

If you have to ask …..

We’re discussing audio blocking capacitors; elements in the signal path that our music has to run through to get to our ears.  These capacitors block DC and let AC pass through – AC being the essential element of music – DC is needed for things to work but we do not want it in our […]
