VINYL TRUTHS: The thing is, we tune and tailor our setups to match the limitations of our primary sources. This can lead to over-reaching proclamations that one medium is better than another when the truth is not that at all.

TAS reviewer Michael Fremer has an extraordinary music system—the best vinyl setup I’ve ever heard. And it makes sense that he does. Mike’s spent a lifetime learning about vinyl audio reproduction and hand selected the best equipment in the world. His digital setup played through that same setup doesn’t quite match my own. That also […]

PS AUDIO: The significance of the folding transmission line in a loudspeaker?

What is the significance of the folding transmission line in a loudspeaker? My guess is that not many of you have heard of a folding transmission line in a loudspeaker, much less ever heard one working.  The late Bud Fried, from Fried Audio (pronounced “freed” as opposed to what one might do with eggs), was […]

ROLLING IT OFF:

Paul McGowan writes ….. Recently I explained the real problem in using a direct coupled product like a power amp or preamp is not the DC they produce, which is minimal at best, but how these products handle DC from OTHER products.  If the designer has built the classic “DC to light” amplifier,  you risk […]

Where’s the music supposed to be?

Visiting audio clubs, dealers, trade shows and people’s homes is illuminating to me. I am always learning. Recently I sat in front of a dealer’s high-end demo system and was amazed at how wrong the image was. The entire presentation of the music was between my seating position and the loudspeakers: a logical place for […]

IMPEDANCE: Mix and match impedance

Popular audiophile lore has it that a mismatch in impedance between the preamp and amplifier will result in bass loss. Yup. If the amp’s input impedance is too low weaker bass will be the result. That’s true in the same way it’s important to pump the car’s accelerator before starting it. In the days of […]

SILENCE: What is it about the sound of audiophile silence?

Yesterday’s post sparked a number of comments and observations and one that came to the forefront was the ability of the subwoofer to help with a sense of space – not just hitting lower bass notes.  We all recognize a sub’s ability to produce the lowest notes of a piano or organ, T-Rex stomping and […]

HEADROOM: The ins and outs of headroom

Recently we covered one of the advantages of the higher power supply voltages afforded by tube circuits: linearity.  Today we’ll jump into the second advantage of increased voltage, headroom in power amplifiers. Headroom is a funny thing.  If you take a SET amplifier of perhaps 18 watts and try and get 20 watts out of […]

NELSON PASS: He designed an interesting product called the Shadow a while ago.

It was an active bass correction device that made sense – because instead of correcting the output of the speakers for bass problems in the room – it fixed the room itself and left the main speakers alone.  Not sure whatever happend to it but it mirrors an idea I’ve had for years: fixing the […]

CAUTION: This is the same technique used by a magician trying to trick you

Originally published 2016 In a recent post I apparently gave out a bad link to this fellow’s video so here’s another.   In the video, when you get a chance to watch it, you’ll probably pickup quite a few valuable tidbits of information and get a good view of how an engineer might tend to look […]

Once the homemade power cable was finished I immediately connected it to the preamp. Interesting.

Once the homemade power cable was finished I immediately connected it to the preamp.  Interesting.  The most immediate thing I noticed was an increased openness without brightness that was never in the design before.  Separation of instruments was greater, soundstage deeper, all the good things you’d hope for.  However, there was a tightness to the […]

NOT AN OXYMORON: Can modern music be high-end?

Paul McGowan: If our definition of high-end is lifted from The Absolute Sound Magazine’s tenet: “the sound of unamplified instruments and/or voices as heard in a natural, acoustic performance space” then does it make sense that modern electronic or multitracked music can ever be considered high-end? I believe it can, but not before broadening our definition. […]

Taming the top end

Perhaps one of the most frequently asked questions is how to tame an aggressive top end. The culprits are almost always dome tweeter offering greater detailto the music. And that’s the catchphrase to be wary of. It’s not that I have something against domes. I’ve heard a number of fine examples over the years. It’s just […]

PS AUDIO: It’s fundamental

Paul McGowan writes: I’ll get back to analog output stages soon enough but I got waylaid on our Community Forums area by an article posted by one of our Community Leaders, Gordon.  The article is about how the ear works and, if you’re interested, you can read it here. I find all this interesting because […]
