The Mac Mini as a High-Resolution Audio Server
Dr. AIX (Mark Waldrep from AIX Records) recently published an excellent application note titled "My First Server" - a simple step-by-step guide for setting up a High-Resolution Audio (HRA) server. Dr. AIX chose a Mac Mini, a Benchmark DAC2 HGC, and the highly-acclaimed Amarra playback software.
The system components are:
- Mac Mini
- Video Monitor
- Benchmark DAC2
- Amarra Playback Software
- Headphones (or Speakers and an Amplifier)
The result is a true High-Resolution Audio system that can deliver the finest studio-quality playback available. The Benchmark DAC1 and DAC2 converters have become standard fixtures in many of the world's top recording studios and mastering rooms. They have become the converters of choice for critical listening in these professional environments.
"My First Server" describes the server that Mastering and Recording Engineer Mark Waldrep uses in his own living room. With his simple guide, you can enjoy mastering-quality High-Resolution Audio playback.

The Audiophile Wild West
Audiophiles live in the wild west. $495 will buy an "audiophile fuse" to replace the $1 generic fuse that came in your audio amplifier. $10,000 will buy a set of "audiophile speaker cables" to replace the $20 wires you purchased at the local hardware store. We are told that these $10,000 cables can be improved if we add a set of $300 "cable elevators" to dampen vibrations. You didn't even know that you needed elevators! And let's not forget to budget at least $200 for each of the "isolation platforms" we will need under our electronic components. Furthermore, it seems that any so-called "audiophile power cord" that costs less than $100, does not belong in a high-end system. And, if cost is no object, there are premium versions of each that can be purchased by the most discerning customers. A top-of-the line power cord could run $5000. One magazine claims that "the majority of listeners were able to hear the difference between a $5 power cable and a $5,000 power cord". Can you hear the difference? If not, are you really an audiophile?
Making Sound with Plasma - Hill Plasmatronics Tweeter
At the 2023 AXPONA show in Chicago, I had the opportunity to see and hear the Hill Plasmatronics tweeter. I also had the great pleasure of meeting Dr. Alan Hill, the physicist who invented this unique device.
The plasma driver has no moving parts and no diaphragm. Sound is emitted directly from the thermal expansion and contraction of an electrically sustained plasma. The plasma is generated within a stream of helium gas. In the demonstration, there was a large helium tank on the floor with a sufficient supply for several hours of listening.
While a tank of helium, tubing, high voltage power supplies, and the smell of smoke may not be appropriate for every living room, this was absolutely the best thing I experienced at the show!
