AX-2014-04 This month’s audioXpress reviews the different approaches in microphone placement techniques for capturing and recording unamplified acoustic music, particularly classical music. A recent study and AES presentation has reignited this issue and our author Gary Galo decided an historical perspective was needed in his article “Stereophonic Recording: What Do Listeners Prefer?”

In our usual review section, we give a listen to the new Focal Spirit Professional Headphones, the first effort of this kind from the prestigious French manufacturer. Miguel Marques tested the Focal Spirit Pros in a quest to discover what this new model brings to an already crowded and very competitive headphone market.

Interested in high-resolution audio? Then you might want to check our Standards Review column, where we examine the recently announced HDMI 2.0 specification. HDMI 2.0 introduces bandwidth support for Ultra HD/4K televisions, adds up to 32 audio channels and 1,536-kHz audio sample frequency with simultaneous delivery of video and audio streams to multiple users.

In this edition, we interview Craig Bernabeu, founder and chief designer of SBS Designs. He created the company with a former colleague to explore “different approaches to record or play back music that would suit my needs” and realize his vision of “US-made high-end designs with a left-field approach available to users,” as he describes it.

Get ready to shake. Mike Klasco’s and Steve Tatarunis’s article discusses structure-borne vibrational energy with “Bass Shakers: Enhancing the Deep Bass Experience with Tactile Energy.”
This month’s Hollow-State Electronics column is dedicated to the “Effects Of Guitar-Amplifier Design On Distortion Sound.” Richard Honeycutt looks closely at one particular amplifier’s design to determine at what stages most of the distortion occurs.

For those interested in DIY projects, you will enjoy a great concept from Michael Rothacher with his LuminAria: A SIT Preamplifier. The author intended this preamplifier to be “compact enough to fit in a suitcase” and a “good-sounding, unusual preamplifier with a spiffy set of performance specifications.” He completed the project in two months, and it was one of the highlights at the Burning Amp Festival in San Francisco.

In our Audio Electronics column, we have Bill Reeve’s take on “An Alternative to Linear Regulators.” In the article, he searches for equivalent power-line ripple rejection with less power dissipation, because no one wants to listen to an audio amplifier that hums.

We also included a book review and this month we share what we can learn from a master by reading The Bruce Swedien Recording Method.
