AfterDark. Project ClayX Giesemann KARMANN Server x HANDHARTILO SERIES

Emperor Double Crown Limitied Edition included:
10M Master Clock Input
Adds On

The Giesemann KARMANN Server x HANDHARTILO SERIES - Emperor Double Crown Limited Edition    

This version is designed with high performance at low power TDP CPU from Intel. We have managed to sources the latest 13th generation, the best Intel CPU for Audiophiles, but in limited supplies. This version of CPU can ensure the Music Server running at modernate heat, running fanless to performs most of the complex instruction and upsampling calculation for HQplayer.   

To ensure we have the best sounding for the hardwares, we performs a lot of trial and errors and research effort since 2021. AfterDark. are ambition to build something very unique in the market for Music Server. Therefore, we start to look into the motherboards and card and tried to design a tailor made chassis for music server for audiophile. 

We are innovator to build tailor made products which is years ahead to most of the commercial brand product. So, we invest time for our R&D teams to invent a Giesemann Clock Sync Module (GCSM) to generate the best clocking signal to the motherboard for the heart of Intel PCH chipset, which is critical to generates all the reference clock for CPU, PCIe, DMI, I/O and TSC. The GCSM is designed to achieved the highest quality of clocking performance for all the components to the motherboard and PCIe cards.  image.thumb.png.3220c38a682c3cabd1893f2f5ad08f01.png

AfterDark. Giesemann Clock Sync Module (GCSM) 



With the Giesemann External Reference Master Clock 10M input. The Giesemann Clock Sync Modules (GCSM) will generate the Reference Clock Signal at 38.4Mhz for the Intel PCH Chipset (PLL), the above graph shows how important this 38.4Mhz is. This single frequency will provide the reference point for all the process at the CPU, PCIe, DMI, I/O, All cores, and RAM frequencies will take into account. 

In additional, the onboard LAN USB card and SFP Card will be OCXO optimised by GCSM.  

We designed to use the external power supply for powering the Music Server. This make the EMI and electronic noise much lower, while maintains the lowest heat inside the chassis and this make the huge differences on sounding.  


The KARMANN Server - Emperor Double Crown version will be build with Intel 13th generation Low TDP CPU with 14 core and 32GB RAM industrial custom modules for lowest latency and digitial signal transfer.


Selection of Audiophile Motherboard and tweaks with Audio Components


We choose the Industrial Motherboard after we listen with it carefully at the system. It is always good to apply some Audio Grade Capacitor for the power section for the RAM and this is significant improvement for  sounding. We selected to use the Non-Polar version of Audio Capacitor from Frolyt made by Germany. The sound is much smoother and provide darker background. 



The BIOS will be tweaked with CPU under clocking and Memory under clocking, we always keep the electronic to be run in under clock and maintains moderate heat for CPU and Memory. This keep the music server in optimial sound quality and impoves harmonic sonics and were able to tweaks in BIOS levels on motherboard.

High performance Pressive heatsink with latest Graphene Technologies 

Thermal transport in graphene is 14 times compared to thermal conductivity in copper, the server temperature will be much lower with high performance heat transfer from CPU.  


High performance Pressive heatsink  


The heat from CPU and motherboard will be transfer via the top of the Carbon Fiber Top plate. 

What is special on KARMANN - Emperor Double Crown?

  • Windows 11 OS is pre-installed in the seperate 1.0TB M.2 industrial grade SSD to reduce time latency and fastest performance in indexing for Roon Server application
  • Standard Included: Music Storage 8TB SSD made by Samsung for storage the master grade music files, the SSD can provide more smoother sounding and no noise when comparing HDD. 
  • AfterDark. Giesemann Clock Sync (GCS) 10M Master Clock modules is pre-installed to provide the best clock signal to the motherboard, and PCIe card, to ensure all music is transfer in lowest time latency. 
  • SFP modules can be connect directly to latest EtherREGEN gen2 to provide physical isolation from server to switch. 
  • Flexible design to run software router in VMs with 1 Lan ports and 2 SFP ports configuration. 
  • Fanless designed on all modules with no noise 
  • All BIOS is heavily tweaks and sound tuning software including the Fidelizer Pro is full licensed and tuned by AfterDark which improve music playback in more organic ways. 
  • With the helps of heavily downsized OS with much less process, the music server can boots up in just 4 seconds. 
  • Power Supply from external LPS with 19V 7A 
  • Plug and Play for music lover. 

KARMANN Server will be the very first Music Server in the market which is build in SFP Fiber NIC Adaptor with OCXO clock build inside for motherboard.
