Von Schweikert Ultra 55 speakers ($120,000 in Porsche Oslo Blue) are the company's smallest flagship-level offering, but still reference-level in capability with a response specification of 20Hz-40kHz. In practice, they delivered a completely enveloping and absorbing musical presentation.

Over the last 50 years, I must have installed well over 1000 phono cartridges, but I still remember the very first one: a Goldring G850 I put into the family Garrard Autoslim turntable when I was 11 years old. In 1973, the G850 was the least expensive moving magnet cartridge Goldring made. The change from the flipover-stylus ceramic cartridge that came with the Garrard wasn't an attempt to satisfy a youthful audiophile itch but, rather, a result of my first encounter with a system compatibility problem.

A few months earlier, I had convinced my nonaudiophile dad to upgrade the family stereo. We went from our ancient Monacor SMX-50 tube receiver to a pretty weird but less ancient Sony all-in-one cassette system called the TC-133CS. I failed to understand that the new Sony's magnetic phono input was incompatible with our old ceramic cartridge. Once I figured that out, I tried to convince my dad that what we really needed was a Shure M75ED. After all, that cartridge came from the same company that made the legendary V-15 Type III, widely regarded as the best cartridge in the world at the time. My dad, however, had different plans. Guided by his home-product purchasing bible, Consumer Reports, he decided we should go instead with the less-costly Goldring.

Ken Songer of Songer Audio must be on to something because his demo led me to experience a heart rate of 141 while listening to "Sharkey's Day" from Laurie Anderson's Mister Heartbreak.

The Van Zyl Audio Alpine mid-horn speaker ($12,000/pair) is designed to cover a frequency range of 125Hz up to 20kHz. It uses a horn-loaded 8" Tang Band full-range driver that connects to the amplifier directly, free of crossover componentry. The design adds a physically time-aligned AMT tweeter—implemented as a super tweeter—to extend the highs with a simple first-order crossover applied.

Ted Denney used a top-tier stereo system to demonstrate Synergistic Research's latest product, the Voodoo Streaming Server ($14,995), at the inaugural Southwest Audio Fest. The demo also included the Vibratron SX ($3995), a passive resonator design from the company's early days.

With the consumer version of the Planet Venus Spectral Coherence Control Essential plugin ($189), adventurous audiophiles can experiment with removing distortion inherent to a recording, independent of the playback system.
