MECHANICAL vs. SOLID STATE: “Relays are expensive and cumbersome”

Paul McGowan / PS AUDIO When we need to switch inputs on an analog preamplifier we use a switch. The kind of switch we use affects sound quality. For years we had only mechanical switches from which to choose. Standard switch contacts in those days were nickel or tin-plated while the more expensive and better-sounding […]

NOISE REDUCTION: Remember back in the day when Dolby noise reduction was the thing?

PS AUDIO / Paul McGowan I remember thinking to myself; this is nothing short of magic. Kind of like the RIAA. Boost the heck out of the high frequencies and then run them through a low pass filter to make everything right again. In the process, hiss is lowered. Magic. What’s worth noting about this […]

ADJUSTING FOCUS: Knowing where to focus one’s attention is often difficult in our technically complex world. Take, for example, the case of fiber optics.

Paul McGowan / PS AUDIO We know that galvanic isolation can make a big difference in digital audio. Any owners of the new DirectStream MK2, with its ability to switch on and off the isolation of every input and output for best sound, can attest to the benefits of customizing levels of galvanic isolation. So, it […]

PASSING TRAINS: To me, it’s more like waving at a passing train. Interesting for the half-second I see a familiar face and then they are gone.

Paul McGowan / PS AUDIO I have probably spent a total of 5 minutes on social media. Facebook, Instagram, Tick Tock, and whatever new connection program out there has zero interest for me. It feels like a potential blackhole vortex waiting to suck me in and chew up my time without any obvious benefit. The […]

DIFFERING VIEWPOINTS

Paul McGowan / PS AUDIO Let me share an interesting experience. At Octave Records, we have built a state-of-the-art mix room with the best equipment we know to exist: FR30 loudspeakers, BHK monoblocks, BHK pre, DSMK2, Audioquest Dragon cables, a pair of custom 21″ subs. Fed from Octave masters, it sounds amazing. And in Music […]

CONVERSATIONS WITH COLIN: QUAD – what wire for rewiring their power amps please?

Dear Colin, I’ve just picked up a Quad 405 ready for service. When I serviced my previous 405 I used the Dada kit which came with the necessary wire. Can you tell me please what size / gauge wire I should use to replace the existing power wires? Would this be suitable? http://www.rapidonline.com/design-te…0m-reels-62317 or could […]

WE’RE NOT EVEN CLOSE

Paul McGowan / PS AUDIO Part of the joy and privilege of being involved in both the recording and playback chains is the chance to grow and learn: new methods in recordings of miking and capturing sound and, in the reproduction chain, new circuit topologies and silicon. Recently a fellow recording engineer working with the […]

3 STEPS TO NIRVANA

Paul McGowan / PS AUDIO In a recent post, Differing viewpoints, I reported that the difference between two identical systems—Octave’s mix room and PS Audio’s reference room—was big enough that I developed a new mixing routine of listening to both. I start with the closest, most intimate of the two systems—that of the mixroom—and move on to […]

UNDERSTANDING: Jitters

Paul McGowan / PS AUDIO Jitter, also known as timing deviation, is the variation in the time interval between two consecutive digital audio samples. This timing deviation can cause easily heard distortion in high-end audio systems including a loss of clarity, definition, and detail in the music, as well as a smearing of transients. Jitter […]

THE PERFECT SPOT: Your seating position IS compromised

Paul McGowan … If you’ve done your system setup homework your chair sits at a comfortable distance from the loudspeakers. With the precision of a ruler, you’ve tweaked and adjusted the speaker’s position for best imaging. Though we call it the sweet spot, it’s certainly not the perfect spot. Within the boundaries of most rooms, the perfect […]

OUR VIEW: The impact, or not, of social media on Hi-Fi retailing

The potential impact of social media when applied to audio retailing is vast and far-reaching. It has the potential to revolutionize the way audio products are marketed, advertised, and sold. Companies can use social media as a platform to target potential customers and increase their brand visibility. For instance, audio companies can use social media […]

UNDERSTANDING: High voltage and linearity

In a recent post we covered the fundamental differences between tubes and transistors and one of those we’re interested in is linearity. Tubes and transistors are only partially linear devices – which means they will not always faithfully reproduce a larger version of the input signal on their outputs. In our example yesterday we placed […]

EXTERNAL vs INTERNAL / Is it better to have the loudspeaker crossover inside or outside the loudspeaker?

PAUL McGOWAN / PS AUDIO I was recently asked an interesting question. Is it better to have the loudspeaker crossover inside or outside the loudspeaker? At first, the answer seemed rather simple. Inside, of course. Shorter wires, fewer binding posts, etc. Yet, in thinking about it, I can see at least one advantage to an […]

BRINKMANN: La Grange and one of the world’s first fully balanced vinyl replay systems

Originally published here in February 2006 Howard, is it true that way back you were the owner of the World’s first fully balanced vinyl replay system? Possibly the first; certainly one of the first three ….. so I’m told. I purchased the Brinkman 10.5 tonearm before I became a dealer, and paid £2,200 from the […]
