The legendary component manufacturer, Audio Research Company, has returned to Seattle at Jaguar Audio. ARC has several newly redesigned tube and solid-state models, and more coming. These are some of the best-sounding components in ARC’s 56-year history. Jaguar is here to discuss which ARC models will work best in your system, and free fly-in setup is included with many.
All components in BOLD are loaned; all components in standard face are owned by me. Last updated 07/15/2022

My listening room is of irregular shape, being 12.5' wide x 13.5' long in the right section, and 18' long in the left (equipment) section, with a ceiling height of 8'. It is cambered left and right, with no perpendicular edge on the sidewalls to ceiling transition. Construction was done with 2" x 6" studs, wall-within-a-wall on the left and right sides (media storage in a room to the left, equipment storage in a room to the right). The room is on the second floor, directly over the garage—no competing sounds. The neighborhood is quiet, being located on top of a hill some 500 feet above the valley below, the listening room faces south, away from the main access road. I've measured the room's noise floor using the AudioTools app with my iPhone 6+ at 30dB, a very good number for the "real world." In other words, pretty bloody quiet.
Power to components in the listening room is fully dedicated. 10 gauge Romex was pulled directly from the panel, all from the same pole to avoid ground loops. Four 20 amplifier runs were done, and Tesla Flex and JENA Labs cryo-treated AC receptacles were installed. All lights and peripheral components are on separate circuits. Circuits have been tested for proper ground and polarity.

The home theater system is housed in our great room. The dimensions are 18' wide by 24' long, with a peaked and vaulted ceiling that's 16' high at the center of the lengthwise room line. The fireplace forces a "shift left" of the High Definition TV and the L/C/R playback, a necessary compromise that skews the sound somewhat, but still allows for a satisfying home theater/surround sound experience.
