AUDIOPHILE HALL OF FAME: Candiates?

There are many great designers out there, and especially in the lore from the golden age, but I’m not to familiar with them.

PS AUDIO: What is this defense mechanism? It’s not in your ears but rather your brain

I learned a new word from one of my readers this morning: conflate.  It means confusing two messages together and apparently that’s what I did yesterday in my post; so I’ll start by clearing the conflation up. I first defined what I believe Listener Fatigue is and then went on to describe how music communicates […]

ADDING CAPACITORS

For the last post in this impromptu series let’s look at my goal of somehow increasing the size of power supply capacitors within a unit connected to a Power Plant. On the surface, this seems like a crazy goal. How can we affect something internally? First, let’s think about what happens when we increase the […]

CONFIRMATION BIAS

Paul McGowan Wikipedia describes Confirmation Bias as this: The tendency to search for, interpret, favor, and recall information in a way that confirms or supports one’s prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing […]

TRANSPARENT IMAGES

There’s something very wrong with the idea of a transparent image. If it’s transparent it means we can’t see or hear it. And yet, the term has great meaning. Our audiophile lexicon is a wonderful tool for communicating with each other. It does seem to fall a bit short when conveying a sense of what we […]

POWER LINES: The dedicated ones

Paul McGowan: If you’re serious about building a high-performance audio system you have to pay attention to the AC power. It’s a constant theme with me because power is the foundation of our systems. There aren’t many great structures standing on weak foundations. Power Plants solve many problems but they need a head start. One […]

DIY: Cables?

Gentlemen, can home made cables really offer quality as distinct from value? Here’s what Paul McGowan (PS Audio) says on the subject. Fatter wire sounds fuller, skinnier wire sounds thin, shielded wire sounds cleaner but veiled, stranded wire sounds one way and solid core thicker wire sounds yet another.  These findings were very suspicious to […]

SERIOUSLY: Speaker size should match the room

Paul McGowan writes …. This fact or fiction question is an interesting one because the notion of matching speaker size to room dimensions is so ingrained into our culture as to be taken for fact. But, some facts aren’t true no matter how much we want them to be. Here’s the deal. Any size loudspeaker […]

THD less than audibility. Now there’s a spec I can live with

Zero calories? Went to cook some scrambled eggs this morning and first sprayed the pan with one of those spray oils. Always conscious of my weight I checked the calorie content: zero.  Zero?  Really?  It is, after all, oil and oil is NOT zero calories. Turns out the agency that regulates the measurement standards has […]
