Community forums 24

Posted 3 weeks ago

The idea of a forum as a place where people gather to talk and exchange goods dates back well before Roman times when they were at their most popular. Forums were the center of each city and had markets and public speaking areas. Today, those same forums are now electronic in nature but their functions remain […]

The challenge of better 41

Posted 3 weeks ago

With few exceptions, I help people’s home systems sound better by pulling their speakers away from the wall behind them. It’s a simple tweak and one that almost always works because living rooms and spouses are generally not happy with large boxes sitting out in the open. The problem stems from an odd collection of […]

The ladder of excellence 19

Posted 3 weeks ago

I remember the very first time I heard a high-end audio system: a pair of JBL corner horns, an Audio Research pre and power amp, and a Thorens turntable. It was a stunning revelation compared to my Kenwood integrated amplifier, AR turntable, and Phase Array speakers. Today that same high-end system that first took my […]

Building rooms 17

Posted 4 weeks ago

In yesterday’s post, I shared with you our progress on building the new Music Room Two, home to Infinity’s IRSV. If you’ve never watched the original video series on building their current home, Music Room One, then I would recommend you join nearly 1 million other people and watch it here. In the meantime, I’ve […]

The IRSV 19

Posted 4 weeks ago

The Infinity IRSV remains one of the greatest loudspeakers ever built. Since its launch in 1985, only a sparse handful of speakers have reached its level of dynamics, transparency, and sheer musicality. It’s not that others can’t. To do so takes a big speaker and a lot of money. Now that we are moved into our […]

Clearing cobwebs 31

Posted 1 month ago

New information, new ideas, new concepts, different points of view all help us clear the mental cobwebs that collect over time. Like our fondness for an old pair of slippers, it’s easier to glide through life’s ruts than to clean house with new ideas. But learning and growing are the secrets to forward motion. One […]

Higher and higher 26

Posted 1 month ago

As the frequency goes up, so too goes the price tag for amplification. Folks aren’t as concerned with the quality of bass amplification as they are with the midrange region but both pale in importance to the attention and money paid to get the tweeter’s range perfect. Think of all the ways we’ve worked on […]

Music’s emotions 52

Posted 1 month ago

As an aspiring author, I understand the mechanics of evoking emotion through well-crafted stories or poems. We relate to collections of words because their meaning often generates empathy encouraging emotion: a smile for the happy ending, sadness at the loss of a friend. Music too can evoke emotion: inspiration from Stars and Stripes Forever, melancholy to […]

Long or short 53

Posted 1 month ago

As our three new listening rooms take shape in the new building it’s time to meet with the electricians to design our equipment feeds. Of course we’re going with dedicated lines: 10 gauge wire with separated ground, neutral and hot. I’ve scheduled 6 runs in each of the two main rooms but already there’s a […]

A matter of degree 28

Posted 1 month ago

Now that PS Audio has moved across the street to our new facilities our old home is vacant. We’ve got to search for a new tenant to lease the space. In the meantime, we have plenty of big, empty, rooms to put stereo systems in. We’ve set up Arnie Nudell’s reference system in the room […]

Paper tigers 28

Posted 1 month ago

There are perhaps as many ways to design a new product as there are new products. Our process is likely unique enough to warrant a few words. When we start a new product the first phase is almost all done on paper, often the erasable whiteboard. These are hazy sketches perhaps of the chassis or […]

When is too much enough? 27

Posted 1 month ago

I am often asked if a certain this or a certain that is overkill. “I have a small room, would a subwoofer be overkill?” I am tempted to turn the question around and ask what size room benefits from a rolled off speaker? Seems to me I always want to get everything on the disc. […]

Right tool, right job 19

Posted 1 month ago

You can make almost anything work. Getting things to work right is a bigger challenge. Take for example a Power Plant AC regenerator. We’d love to use Class D amplifier technology for the output but have consistently stayed with good old Class A/B. Right tool, right job. Class D amplifiers can be terrific for the […]

Acts of kindness 31

Posted 1 month ago

The greatest acts of kindness seem to come from unexpected sources. Let me tell you a little story. When I was a young Groot I was pretty insecure. Sucking my thumb brought pleasure and allowed me to handle the stresses of growing up. It also left me with a pretty severe overbite, one that was […]

Audiophile rating system 42

Posted 1 month ago

While answering a customer’s question about matching amps to speakers an old memory popped into my head. The industry’s effort to craft an audiophile rating system. It was a few decades ago but back then the idea seemed promising. Within the audiophile community, we’d set up a rating system for sound quality to insulate us from […]

Hit and run 23

Posted 1 month ago

From my upcoming memoir 99% True. It all started innocently enough on a lazy Saturday afternoon. My new best friend David—a dark-haired, athletic, alpha male transplant from Dallas—helped me prepare the bait: overalls stuffed with newspaper, a hoodie sweatshirt with a basketball for a head, and Dad’s old boots pinned to the pant cuffs. We […]

A quiet revolution 32

Posted 1 month ago

My father Don was one of the few in our neighborhood that had an actual sound system. It was a cobbled together group of separates: Rek-O-Kut turntable, Stromberg Carlson electronics, homemade speakers. The few neighbors that had sound systems relied upon the classic all-in-one console, while everyone else got music through a simple radio. All that changed […]

Quadraphonic sound 14

Posted 1 month ago

The years 1973 through 1975 saw great changes: our first major recession since World War II and hifi manufacturers declaring two-channel audio wasn’t enough—we needed to double our sound systems. Following the stereo sales halcyon days of the Vietnam War, where container ship loads of receivers and speakers flooded every corner of the Western world, sales […]

Attack of the Floyd 28

Posted 1 month ago

It was a warm, German, summer’s evening in May 1972. Terri and I were in reserved seating, perched above a sea of thousands of stoned, excited, and anxious concert goers. We were all waiting for a once in a lifetime event. Pink Floyd was about to debut an unfinished version of a new album they […]

Moving update 26

Our company has officially moved across the street and we now have a new address: 4865 Sterling. Engineering, admin, and sales moved last week. This week is production and warehouse turn. It’s an all-hands-on-deck process to move a company of our size and we even lassoed my 6-year-old grandson Henry to help! By week’s end, […]

Too much? 71

Posted 1 month ago

The race for dynamic range in the recording industry is over. We won. At the beginning of the 20th century the first sound recordings achieved about 15dB of dynamic range. 30 years later, following the Roaring Twenties and the advent of vacuum tubes, we had doubled that number to 30dB. The march ever forward has […]

Cover up 27

Posted 1 month ago

I was never quite sure why this was a thing back in the 60s but instead of guys taking showers my classmates seemed to like the idea of applying cologne to cover up their stink. I can’t tell you how much I wound up detesting the stench of BO covered by Jade East. My view […]

Sensing the right thing 32

Posted 1 month ago

A servo system is a generic name that has many meanings depending on who is using it. To me, a servo woofer system involves a motional feedback element capable of measuring the woofer’s acceleration and position. To quite a number of others, a servo woofer can be as simple as another coil of wire on […]

Laser focus 43

Posted 1 month ago

The sharper our focus the narrower our view. We often miss seeing the forest because we’re focused on a single leaf. More than once I have been so pleased with a new setup that I never noticed the channels were reversed. I remember back to the 70s when PS Audio’s co-founder Stan Warren and I used […]

Walsh tweeter 39

I remember with great clarity my first meeting with Infinity founder Arnie Nudell after he left the company. My friend and TAS publisher, Harry Pearson, had called me out of concern for Arnie’s mental health hours after the incident. “Arnie’s left Infinity,” said HP, after having tracked me down while I was on vacation in […]
