“The question our industry should be asking is, how do we fit in? “

Paul McGowan writes: People don’t change, but circumstances do. It’s always interesting to me when I hear someone wring their hands and point out that people aren’t the way they used to be.  They’ve changed. I think typical of what you might hear is something like this: They no longer appreciate good music. They’re perfectly […]

FUSES: Fuses!

  How can fuses possibly make a difference? I’m in no way an expensive cable believer, but I do think you need to find something fit for purpose. A fuse is basically a few mm of thin tin wire, so how and why do these sell, and for so much! [TL: moderating comment: it is […]

Getting what you bargained for?

Paul McGowan writes: In our comments section of PS Tracks magazine I mentioned how we in the high-end got what we bargained for when we chose the lowest price over service and advice.  I thought it would make a good post on its own. Dealers have always discounted.  Even back in the days of famous […]

Paul McGowan writes:  This subject is actually very interesting because this class of amplification device is at the core of almost everything in audio today and while simple on the surface, there’s lots to know.  Therefore I will break this up into a bunch of little posts to help you assimilate the info one day […]

In 1995 there were no easy solutions to this problem but it was possible to build what we wanted.

Paul McGowan writes: In my previous post Jittered, we used a water flow analogy to further our understanding of jitter and how to make it go away. You’ll remember that jitter is all about timing and making sure that the digital audio bits arrive on schedule without any slow downs or speed ups to their […]

PS AUDIO: Anything that gets me closer to the goal of having live musicians playing in my room is good.

  Paul McGowan writes: I’ve been thinking recently about our discussions on tone controls a few weeks ago. Initially I objected when a commenter suggested we could use tone controls selectively to improve recordings.  That seemed to violate the purity of the recording.  After all, isn’t the goal to get as close to what the […]

TWEAKS: The cheapest effective one

Paul McGowan writes: David Pogue, one of my readers, suggested to me “the cheapest tweak” that he’s ever tried and I thought it might be interesting, this fine Sunday morning, to give this tweak a try if you’re looking for something to do. The tweak concerns extreme toe in of the loudspeakers – toe in […]

PS AUDIO: In a DAC or a preamplifier, power supplies are also critical but in a very different way

Paul McGowan writes: I think we all understand the importance of power supplies in audio equipment – as everything we listen to in our systems starts out as DC voltage in the first place. Power amps are particularly sensitive to power quality for reasons I’ve detailed in past posts – and of all power amp […]

PS AUDIO: Perhaps the most expensive option a designer has to control the gain is called a stepped attenuator.

  Paul McGowan writes: Perhaps the most expensive option a designer has to control the gain is called a stepped attenuator.  These devices can range from the reasonably simple to the ultra exotic and expensive. Cello’s 59 step platinum attenuator as well as Ayre’s 66 stepped device are exotic, expensive hand built beauties that exemplify […]
