ELMORE JAMES: A very useful mini-biography

Not my words, but …….. “No two ways about it, the most influential slide guitarist of the postwar period was Elmore James, hands down. Although his early demise from heart failure kept him from enjoying the fruits of the ’60s blues revival as his contemporaries Muddy Waters and Howlin’ Wolf did, James left a ……..” […]

Whatever happened to Hi-Fi Shows and the importance of both Patricia Barber and Radka Toneff?

Tony Andrews (contributing editor – jazz) writes: Back in the 1980 and 90s if you were in to Hi-Fi there were some great shows around in the London area. I can remember many happy hours spent at various locations near Heathrow and also at The Novotel in Hammersmith. As venue costs soared and demand dropped […]

The Six Most Overlooked Blues-Rock Guitarists?

Reverend Keith A. Gordon / ThoughtCo writes: Let be honest here, shall we? Blues-rock fretburners like Eric Clapton, Jimi Hendrix, and Stevie Ray Vaughan typically receive all the love while other talented guitarists are too often forced to wait in line to gather up whatever crumbs of critical acclaim remain. These skilled musicians bring plenty […]

The Mysteries, Myths, and Truths about Mr Handel

David Vickers takes an in-depth look at the composer, his life, and works… Not so long ago George Frideric Handel was best known to the general public for a few predictable things: Messiah, being ‘German’, his obesity, and for going blind. Thankfully that narrow perception has substantially altered over the last 30 years. Nowadays we […]

Choosing wisely

Paul McGowan writes ….. In a recent post we decided on the type of output stage we wanted: balanced or unbalanced depending on the topology of the DAC before it or, in the case of a preamp, how extensive the designer wanted to go.  In our case we always spend the extra time and effort […]

While not as overall full and harmonically rich as some …..

Originally published October 2015 Paul McGowan writes: There’s perhaps nothing more important to the success of a hi fi system than the synergy of its parts. We’ve been discussing how the addition of some preamps help the sound of some DACs; a perfect example of the synergistic quality of parts within a system. The speakers […]

Funny how daily life can many times mirror the circuitry that runs our high-end systems.

First published November 2015 Paul McGowan writes: 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 […]

Graphene circuit’s wireless promise – by Paul Rincon

  From the archives The promise of faster, cheaper and more efficient wireless devices has moved a step closer. Researchers at IBM have demonstrated the most advanced integrated circuit made of wafer-scale graphene – often touted as a “wonder material” that could revolutionise electronics. Graphene circuits could allow mobile devices to transmit data loads in […]

How important are dynamics?

Paul McGowan writes …. My very first pair of high-performance loudspeakers were Magneplanars but the marriage didn’t last long. I soon found myself enamored with a different kind of panel speaker, an electrostat which was so much more revealing than the planar that I made the switch. This added window-like clarity was a result of […]

Voicing to old ears

Paul McGowan writes …. Many of today’s audio equipment designers are getting on in years. I am a good example as I creep towards 70. Hard to imagine because in my mind I am still about in my mid-30s. Only the occasional look in the mirror proves that thought incorrect. As we age our hearing […]

Using what we have

Paul McGowan writes …. Most real world home stereo systems are placed in rooms where circumstances permit, not necessarily where they sound best. The last system I had in a home the speakers were on either side of a long couch, their distance determined by the length of the furniture rather than achieving perfect tonal balance. […]

Our path was not an easy one. Where classic tales of well-funded business plans and successful entrepreneurs might describe a lot of companies, it sure didn’t reflect our own.

Paul McGowan writes: Turning a good idea into a company is not easy. The devil, they say, is in the details; something Stan and I found to be true. In this video, Part II of the History of PS Audio, we learn how two wild-eyed hippie audiophiles turned a phono preamplifier into a business that today […]

Are cables BS?

Paul McGowan writes: There must not be enough worms crawling around so I figure I’ll just go ahead and open a fresh can. Keeps it fun that way. Why is it we’re convinced we can hear changes in polarity, or MQA vs. non MQA, or the difference between CD and vinyl—but find it hard to accept […]

Solid state vacuum tubes?

Paul McGowan writes: Most of us like the sound of vacuum tubes on an amplifier’s input: sweet, rich, full-bodied, musical. An equal number aren’t too happy about their downsides: heat, microphonics, size, and the 300-pound gorilla—their ephemeral lifespan. Which is why most customers rejoiced when we began to leverage a solid state equivalent, the FET. […]
