Reference System

Some quick calculation reveals the room is about 600 ft² or some 4300 ft³. Based on room length, it can support full development of frequencies down to about 24Hz, with primary axial resonances at about 44Hz and 78Hz. But the room is amazing sounding, and exhibits remarkably little loading. In fact, during a visit to install and set up my Von Schweikert Audio ULTRA 9 loudspeakers, Leif Swanson, Chief Designer at Von Schweikert Audio said, “You seem to have some pretty cool things taking place with the room. Good length for the bass waves, and those doorways. I notice very little change to the bass walking around the room. You definitely scored with this room.”

Because I began programing in 1971, while a sophomore in high school, and just recently (November 2021) retired as IT Engineer/Analyst who is certified on both Microsoft and Apple platforms, I’ve chosen to build my own Windows based PC as a file server. I started with a Lenovo P320 CAD Workstation, using a Samsung EVO Plus solid-state drive for the OS, and featuring an Intel® Xeon® 3.50GHz quad core CPU running 8 Logical Processors, and with 32 GB RAM. Files are served over Network Attached Storage using a sonically chosen Cisco router system using all Audience Hidden Treasure Ethernet CAT7 cable, and I have installed the Hidden Treasure SATA cables inside the Workstation.

The computer is further optimized using Fidelizer 8.8 (https://www.fidelizer-audio.com/), an installed optimization utility that allows leveraging, managing, and prioritizing a computer’s core functionality, services, and processes. My primary streaming and music management software is Roon 1.8, but I also employ J River MediaCenter 28. The stream is transferred from my Media Server to my DAC by means of an Audience frontRow USB cable. Given the way most DACs see DSD files, I have found USB connectivity to be the most effective overall.

The tweeters of my Von Schweikert Audio ULTRA 9’s are centered 1′ 10′ from the sidewalls, and 7′ from the wall behind them, with a toe in of about 8 degrees. The prime listening area is centered roughly 12′ back from the plane of the tweeters.

Room taming is achieved with the use of RoomTunes Corner Tunes, two Echo Tunes (one each at the tweeter’s primary reflection points on the ceiling), and the surprisingly effective Shakti Innovations Hallographs. Two 6-foot-tall by 4-foot-wide panels of Auralex Studiofoam Wedgies provide absorption at the first side-wall reflection point for the speakers.

Power to components in the listening room is fully dedicated, with a separate 20-Amp service run from the panel for the amplifiers (main audio and subs), and another separate 15-Amp service run for the sources and other electronics. All other devices on that level of my home (computers, lights, printers, televisions, heating/AC, etc.) are on separate, isolated circuits. At the time the new services were run, I also had the whole home grounding system redone, including the installation of new grounding rods, in order to both comply with the current National Electrical Code standards of achieving A resistance of 25 ohms or less, and so as to not introduce any unnecessary noise into the power delivery system, in an attempt to provide the highest degree of sonic accuracy possible, ensuring the blackest of backgrounds, improving the pace, rhythm and timing, and painting a wider, deeper, and taller soundstage, including better separation of vocals and instruments.

Those who know me (or have read my work over the years) know that my system MUST be tonally accurate, strikingly neutral, stunningly transparent, and jubilantly musical. However, open, detailed, and layered soundstaging, combined with realistically sized and spatially accurate images, are every bit as important to me as truthful timbre and musical bloom. With the right recording, this system whisks you back to the venue or hall of the original performance for a spooky-real recreation of that event in the here and now.

I have had any number of audiophile and musician visitors’ remark on the power of the listening experience as witnessed from my chair. Musicians from any number of genres of music, from Salsa to Rock ‘n’ Roll to Classical, have actually wept after or during a listening session, and audiophiles of many years have remarked things like, “What more could you ask for,” and “I’ve never heard a rig sound ANY BETTER than this.”

While those are encouraging words, and seem to indicate that I’m doing the right things with component and cable selection as well as room set up, my system (every system? ;-D) must be seen as an ongoing work-in-progress. Every once in a while, the addition of some new piece, be it a source, a cable, or an accessory, allows me to move just a little closer to that actual musical event. The journey continues….
