THE (KOREAN) WALL OF SOUND

South Korea Punishes Kim Jong Un with K-Pop for Nuclear Test,” says it all. K-Pop isn’t the Grateful Dead, but then, the exercise is meant to challenge the North Korean government’s near-absolute control over the information that goes into the country.

The broadcasts range from “K-Pop and recordings of casual conversations to discussions about the importance of human rights and the lives of South Korea’s middle class.”

No word whether there will also be a corresponding internet radio station.

REGA EAR (mk1) HEADPHONE AMPLIFIER

Big, open, and spacious, the sonic profile of the Rega Ear has, in some ways, defined what ought to be possible at its price point. And as with all gears Rega, its rhythmically kept.

The presence of an proper power supply – an external linear design placed apart from the circuitry – allows the Rega Ear to hang on to its place as a headphone amp with power, weight, and a touch of warmth.

Meaning it’ll pair with almost anything you can plug into its 1/4″ jack, from the Sony MDR-7506 to the demands of a Sennheiser HD600. Just what you want from a standard bearer. While there are newer, less expensive amplifiers that are storming the market, its difficult to beat a well-executed, proven design.

Here’s a look inside.

journeymantoolbox: That was the idea when we took off the top! We were trying to figure out more of its specifics.

"There's no such thing as digital." - Audiostream.com
  • Audiostream: It's common for people to envision and represent a digital signal as a series of 1s and 0s. As such, there's really no room for error, at least according to this binary theory. Is a digital signal simply a series of 1s and 0s?
  • Charlie Hansen, Ayre Acoustics: Unfortunately not. The "1"s and "0"s are just abstractions that are easy to think about. But in the real world, something real needs to represent those two abstract states. In modern digital electronics, we have almost universally chosen a voltage above a specific level (that varies from one "family" of electronic parts to another) to represent a "1" and a voltage below a different specific level (that again can vary) to represent a "0".
  • In the real world, those two voltages are not the same, so there is a "grey" zone between the "black" of the "0" and the "white" of the "1". Also, it takes time for the signal to change levels, and the time required to do so can depend on dozens (or even thousands) of other external factors.
  • All of this can be boiled down to a simple phrase. "All of the problems with digital are analog problems."

Twin Tamura transformers. Parts of this quality are a rare sighting in any component, particularly a digital-to-analog converter. In this case, the made-in-California Muse Model Two Plus DAC. This dual arrangement separately powers the digital and the analog sections, allowing each side to perform its best.
