Electronic Adjustments  Ok, now that we’ve accomplished the bassic (pun intended, sorry!) steps, we are on the home stretch.  These final steps require personal choice/taste as well as some technical adjustments. In...

Leon

2016 has been a helluva year. You know: the list of musicians and music-related people who have passed, in any one year, would be too much; David Bowie, Paul Kantner, George Martin, Prince, all of...

Do You Even DIY, Bro?

Darren Myers’ Make It Yourself articles, run in Copper issues 15, 16, and 17, are among the most popular articles we’ve ever run. Unfortunately, projects take time to develop: plotting, postulating, obtaining parts, documenting the project, building...

"Snakebit"

Growin' Up Together: Stevie Wonder

Starter Kit

Black Friday

I wondered when the term “Black Friday” came to mean the launch of the Christmas/Hanukkah selling season on the day after Thanksgiving. In my mind, “Black Friday” referred to the...

Bluegrass In the Dark: Doc Watson

I have to tell you, blind musicians fascinate me.  Not because they obviously can play without looking.  I have been doing scales up and down various necks as long as...

Mass, Massive, Massless

I’m fascinated by materials, which I ascribe to a childhood obsession with spider webs: how could something that’s barely there, be so strong? In college I focused on materials science...

Where Will We Go?

Gentrification. Some view it as imperialism incarnate, a way for big companies to force out long-established, historically-important businesses and create yet another outlet for their overpriced, overhyped goods. Cynics and...

Objective? Subjective? Who Cares?

Part 1: Human Nature. We just don’t get no respect, us audio engineering types.   After all, we were the kids who founded audio clubs, spent our free time at whatever...

“CNC” Moving Magnet Cartridge Phono Stage

My friend Bill and I wanted a simple phono pre-amp for shop use, one that was not expensive but would give high end performance. I like the KISS principle and...

A Case of the Jitters

Let’s take our good old standby, the Red Book standard of CD Audio, where we sample using 16-bit data at a 44.1kHz sample rate.  This sample rate implies a series...

Fifty Years After

Welcome Back, My Friends...

Subwoofery: ...

The Listening Position: This series was implemented to assist music-loving audiophiles in gaining much more musical involvement with their systems that feature “full-range” loudspeakers.  As such, it is not about...

The Once and Future Tweeter

Back in the day, I had many an asthma attack induced by musty old magazines purchased at yard sales and flea markets. I loved car magazines, hi-fi mags, and especially...
