Below is a summary of the Main System and its operational components in May 2023. For a full list of all HFA Reference equipment and accessories, see Associated Equipment.
The main change from the last incarnation is that I removed the turntable and phono stage to focus solely on digital with this system. Along with this, the Antipodes K50 was exchanged for the OLADRA.
The core of the main system consists of the CH Precision C1.2 DAC, L1 preamp, A1.5 power amp with the Grimm MU1,Antipodes Oladra, 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 Driade Flow Reference 808.
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.

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.

Hi Chrisitiaan,
I have a ch precision A1.5 amplifier and was wondering if you still use a GigaWatt PowerSync ULTRA cable with the A1.5 or if you have tried other C19 cables ?
Best regards,
Sébastien
The CH A1.5 has a 20A connector, incompatible with the GigaWatt cables I have here. For the longest time, I have used it with the stock cable, and lately am using a Belden 19364 cable. I do use the PowerSync ULTRA with the L1 preamp, and the LC2 EVO with the C1.2 DAC.
Thanks for the details. I thought you’d also had a chance to test the PowerSync Ultra with 20A connector on the CH A1.5!
What IEC C19 plug did you use on the Belden cable for the CH A1.5?
The current 20A plug that I use with the CH A1.5 is nothing special. Standard entry-level German brand, but sounds good, better than some high end alternatives I tried. I think the brand is Schurter. Alas, there are not many 20A connectors to choose from.
