Summary<\/h3>\n

This is an overview of the Main System and its operational components as of February 2026.<\/p>\n

The main system is always assembled and is used for most private listening and reviews. This system consists of the CH Precision C1.2<\/a> DAC, L1<\/a> preamp, A1.5<\/a> power amp, Antipodes Oladra<\/a>, Grimm MU1<\/a>, and Taiko Audio Extreme music servers, and Refoiled Apogee Duetta Signature speakers with the latest-generation Graz DSB-KLM woofer foils and KLM7 MRTW foils, installed in August 2025.<\/p>\n

Loudspeakers<\/h3>\n

The Apogee Duetta Signature ribbon speakers are permanently set up. They were refurbished and fitted with the latest-generation Graz DSB-KLM woofer foils and KLM7 MRTW foils in August 2025.<\/p>\n

Racks and Platforms<\/h3>\n

All CH Precision components are placed on an Artesania Exoteryc<\/a> rack with Carbon Fiber Linear Arms<\/a>. All digital sources are placed on two HRS EXR<\/a> racks. Review components will be assessed on a vacant spot in one of the HRS EXR racks or on\u00a0an Artesania KSH2 Krion shelf<\/a> coupled via Artesania Carbon Fiber Linear arms<\/a> to an Artesania Aire<\/a> Floor Platform. In essence, the Aire is a lower Exoteryc rack, and it sounds identical. All racks have Artesania discs as floor interfaces, Panzerholz for Artesania, and Carbon Fiber for HRS.<\/p>\n

Cables<\/h3>\n

The main digital AES\/EBU interlink is the Network Acoustics muon2 Balanced Digital Cable<\/a>. All analog interlinks are Driade Flow Link Reference 808<\/a>, both balanced and unbalanced. The speaker cables are the Driade Flow Reference 808<\/a>.<\/p>\n

Power<\/h3>\n

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<\/a> behind the audio system. For the Network Switch, Music Servers, and some temporary equipment, I use two power distributors that started life as Pawalle TP-80s but are used only for the enclosures, stripped of all internals and everything replaced with selected wiring and components. The rest of the system is powered directly from a PS Audio Power Plant P20<\/a> power generator.<\/p>\n

Power Cables<\/h3>\n

The power cables are a mix of brands and OEM home-made specimens. The GigaWatt LC-2 EVO<\/a> is permanently used with the CH C1.2 DAC, and the GigaWatt LC-2 EVO<\/a> is permanently used with the CH L1 preamp. The CH A1.5 power amp is the only component still using a Belden 19364<\/a> power cable. The Network Switches and specific temporary digital components are powered using home-made cables based on Block CUL 500 Enameled solid core copper in PTFE tubing with OEM Rhodium schuko and Oyaide 004 IEC. The other permanent components are powered using home-made cables consisting of OEM tinned litze in PTFE dielectric with OEM Rhodium-plated schuko and Oyaide 004 IEC. Review components are assessed using the best cables for the given product.<\/p>\n
