Information on Diretta

What is the special about Diretta Network Bridge Mini NS1 ?

On Hardware Levels:

• The motherboard is heavily tweaked and removed all the parts which is not used for audiophile for EMI noise reduction
• 5V 2A input with 2.1mm DC socket, to enhance the listening pressure with high quality LPS
• USB DAC supports for all models which runs Windows / Linux with XMOS USB generic drivers
• Three USB ports, which can connect ro three USB DAC at the sametime. Software selectable on Diretta Host Setting.  

On Software Levels:  

• The diretta license and FW is included inside the motherboard.  
• Plug and Play to audiophiles.
• AfterDark. Diretta Host Software will be provide under the software below, and only can only be used to activated with AfterDark. Diretta Target. 
• Windows OS / Linux Version for Diretta Host 
• After Installed Diretta Host, the USB DAC will be Roon Ready / HQPlayer Ready via Diretta 
• Thousand of mix and combination setting of parameters for different sound tuning for audiophiles systems.

The Background of Diretta 

Why most electric noise is hard to filter at the network?

• Most of the switch can reduce the power- supply noise generated by DC-DC conversions. Using some Audio Capacitor near the DC sources, can reduce some noises. 
• Some circuit designer may apply some low-pass filters and reduct splike like digital-specific noises.
  • However, we it will harm the sound, it is because the filter may filter out some missing information, that is not actually a noise at all, for example, the white noise, which have some extra information to the background, which make music more organic.
  • This may make music digital and harsh as a result of too much filters.

It is absolutely difficult to electrically eliminate the noises. Diretta is going to solve this problems in 2 steps...

An intergrated Diretta Device with DDC + Diretta ASIO protocol network optimization 

Diretta ASIO optimised and reduce network noises?

• Averaging the network processing, moderated the power consumption and current. 
• Use of Target and Host Server concept to reduce network traffic 
• The Host (Roon Music Server) sync the Target device, with more packets at short time intervals, to average out the peak traffic, the transmission is controlled by setting the Target buffer. i.e less electric use, with less noise during transfer
• The preset profile amd ASIO Buffer can be use to fine tune the sounding.  
• We perform testing on Cascade of Buffalo BS-GS2016, the result is just amazing.
• Huge improvement on music playback with HQPlayer x Roon x Diretta ASIO

Testing Enviroment : Fidelizer Pro 8.8 x HQplayer x AfterDark. Diretta ASIO x Roon x MinorityClean 235 running on Windows Server 2022 Datacenter OS

AfterDark. Partners with Fidelizer Pro for optimization for Diretta ASIO x ROON x HQPlayer 

We will have group buy for Audiophilestyle.com member for purchase of latest Fiderlizer Pro 8.8 next week…

The result for DSD 11.2Mhz / 22.5Mhz is just amazing, all the infomation is transforming smoothly to DAC

HQPlayer upsampling to poly-sinc-ext, AMSDM7 512+fs, DSD512 via AfterDark. Diretta ASIO to Gustard X26 Pro, decoding DSD512 DoP at DSD 22.5Mhz.  

E.g. The filtering setting for HQplayer, choosing output ASIO device = AfterDark. Diretta. Then Roon is ready to go, and upsimpling via HQplayer. 

Specification:

• Black Modernize Carbon Fiber Anti-Resonance Plate is made of 6mm front / 3mm back thickness of Carbon Fiber Audiophile MAT for EMI shielding and Anti-Resonance for mission critical application for Audiophile Network Switch. The will prevent external noise from getting to the USB signal conductors, and the high performance density of Carbon Fiber Shield to further prevent the ingress of noise (RFI, etc.) and increase stabilization during NAS Music File streaming application.
• Lan port applied with EMI shielding material from KAMET, enhanced audio performance with propriety Carbon Fiber Shielding (CFS) Technology and audio application.
• Project ClayX Black Element Duelund Cable will be used for internal DC power wire.
• Optional Adds on: Independent Black Modernize 5V Linear Power Supply is suggested to placed away from the digital signal board to eliminate the EMI interference and provide more precision and organic sounding. 
• The motherboard is placed on carbon fiber, anti-shock and EMI material is used, to eliminate the signal noise and better separation to avoid vibration interference for mission critical music playback.
• The “Carbonized Screw” was used to fix the position on Black Modernize Carbon Fiber Anti-Resonance Plate for Audiophile devices.
• All hand Made in Hong Kong by AfterDark. x Diretta in Japan
