Below is a summary of the Main System and its operational components in November 20th, 2022. For a full list of all HFA Reference equipment and accessories, see Associated Equipment.
The core of the main system consists of the CH Precision C1 DAC, L1 preamp, A1.5 power amp with the Grimm MU1, Antipodes K50, and Taiko Audio Extreme servers as main sources, and Magico S1 MkII speakers. All interlinks are Driade Flow Link Reference 808, both balanced and unbalanced. The speaker cables are the Mad Scientist Black Magic.
The core components are placed on Artesania Exoteryc racks with Carbon Fiber Linear Arms. The MU1, as well as most review components, are placed on an Artesania KSH2 Krion shelf that couples via Artesania Carbon Fiber Linear arms to an Artesania Aire Floor Platform. The Aire is basically a lower Exoteryc rack and it sounds identical.
The power for this system is delivered by a dedicated run of solid-core installation wire, sourced in the Breaker Box from a Siemens Sitor Cylindric Fuse Cartridge, and ending in three GigaWatt G-044 single Schuko Wall Sockets behind the audio system. I use three metal-cased power distributors, one for the main system, one for analog, and one for review components. The power distributors have a shielded metal case and use simple linear brass strip conductors but they work predictably and provide solid connections.

Hard Wood Stiffening Bars glued onto the windows
The story of my most recent room acoustics improvements is intended for a new installment in the HFA Setup History. Alas, I have yet to find the time to write it as I have to prioritize regular reviews. In short: each of the 8 ceiling-to-floor glass window sections has 4 horizontal hardwood bars glued on using Bison Polymax kit. These bars are then stabilized using thick wood bars that are screwed into the left and right frames. What this achieved is a strong reduction of the glass panels’ 40Hz resonance that killed much of the right speaker’s low output and also introduced very annoying phase effects at higher bass frequencies.
