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 […]

While the high-end is still enjoying a great deal of demand and support, high-end dealers are not.

While the high-end is still enjoying a great deal of demand and support, high-end dealers are not. The state of high-end audio retailing isn’t good; we lose a few each year and they are not being replaced. Some manufacturers are abandoning the high-end retail channel altogether: B and W is a good example.  While not […]

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 […]

Next time you’re evaluating something new in the system take a break and let a day go by before you revisit your decision.

Have you ever noticed that sometimes you’re focusing so hard on a minute details that you miss the elephant in the room?  Happens to me all the time. A commenter to these posts mentioned an AB test he witnessed between two amps and after multiple A/B back and forth tests someone suggested the channels between […]

Most of us are familiar with the concept of mechanically isolating our equipment from vibrations; but do you know why it’s important?

Microphonics.  Certainly not the only reason, but clearly the most important.  Microphonics is the tendency of something to act like a microphone; picking up and reproducing sounds it “hears”. The sound producer is, of course, our loudspeakers – which is why headphones and their associated equipment are far less sensitive and needful of vibration dampers. […]

Audiophile retailing – dealing with the consequences

Maybe Frito Bandito? I promised  to get into specifics about the idea I put forth of manufacturers adopting the Wal Mart approach of not owning inventory as way to get local “audio experts” to become high-end retailers.  Reader Steve Barry (himself once a high-end retailer) pointed out a flaw in that model and suggested something […]

The man who designed everything

In a recent post I mistakenly called the great David Hafler “Bob”.  Oops, I think I had “Bob” on the brain.  Sorry.  But speaking of history, I think the stories of the people in any industry are perhaps more interesting to me than the actual products and technologies they design.  I hope you’ll indulge me […]

Treat the cause or the symptoms?

In light of all the response I got from the latest video of the Helmholtz Resonator I thought it’d be ok to take a short break from our current thread and delve into this for a bit before returning to Direct Coupling. Many of you requested links to the calculators we used to determine the […]

I wonder how many concepts we take for granted were born out of this very same process?

There appears to be an increasing customer frustration level in all sectors of business towards errors in products and services, reported through customer feedback, and the company’s response time to fix those errors. Customer expectation levels for faster error correction, perhaps even elimination of errors, appear to be rising exponentially. Here’s the interesting thing: all […]

Dave Paananen, our director of engineering, asked “Isn’t it obvious the need for an album or CD is rapidly becoming unnecessary?

At first I dismissed the thought, so ingrained is the notion of an artist creating a package around a body of work, but then I realized he is right.  The medium itself has always dictated the package musicians use to wrap around their work. There’s the famous story of Sony founder Akio Morita’s dictate to […]
