Lone Star Audio Fest 2012 Show Report
Report By John Semrad
Audio speakers were driven by a precious little Transcendental Sound T-16 OTL
amplifier that uses eight 6S19π Soviet pass tubes in parallel per side.
In the Crescendo Systems room there was again a huge pair of electrostatic
speakers. These low-distortion panels are essentially hand-made to order and use a
metallized plastic ﬁlm diaphragm and comparatively low bias voltage.
Bob Brines makes the trek to Dallas every year and again had some unique full-range designs
on hand as well as a large open back subwoofer.
More good sound was to be had in Hugh Nguyen's
Angel City Audio room. The ACA Trinity speakers were powered by Melody AN300B integrated
The Melody amps are well designed and beautifully made. Also on display was the Melody Pure Black 101 tube
Soundﬁeld Audio demonstrated some very good sounding speakers, their Monitor 1 which utilizes the new
KEF Uni-Q driver. The low end was provided by a pair of dipole
Another familiar face was Oddwatt Audio and their very affordable system that had a pair of
Martin Logan Preface speakers driven by a pair of Oddblock
monoblocks. All of their electronics are available as kits.
Also on display was the Forewatt Series I
preamplifier kit. More fodder for the ever growing DIY crowd.
Wayne Parham is the force behind LSAF and brings his
Pi Speakers every year. They are medium-sized boxes sporting horn-loaded mid-range drivers and tweeters and
large paper-cone woofers.
