The development of AfterDark. x Diretta

[AfterDark.]

AfterDark. is always looking for innovative solution, to enhance listening pressure with streaming music. This year, we heard there is some positive feedback coming from a Audiophile from France. He wrote a compensive user guide for using the Diretta devices for streaming music from Roon.

 

 The new network protocol called Diretta becomes very interesting for us.

 

We know that the very first product from SPEC -RMP-UB1, is really good sounding and it was recommended by Audiophiles. So, we start to investigate the theory behind Diretta which was founded and headquartered in Japan. 

 

 

First of all, we was thinking that this ASIO Protocol is like the Merging DAC, which use their special ASIO to transfer music via Network called AES67. However, we was wrong, it is not the same technolgies. Diretta ASIO using the another amart approach which like no others in the market. 

 

Few months ago, we started the Project ClayX with Diretta. The development kit is tailor made to us with three different versions. 

1. The Flagship Model called Diretta Lucia in RJ45 & SFP versions 
2. The Newest Model called Diretta Lucia - Piccolo 
3. The Raspberry Pi Edition of Diretta in USB

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 reduct the 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

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…

 

 

Farad Super3 Super Capacitor LPS will be official power supply upgrade for AfterDark. Rosanna Network Bridge x Diretta 

 

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.

Hello, what are the news concerning the diretta development ?

[Datka]

Any update on dirreta project , I have fidata server and wanted to try diretta , 

 

Sforzato transport looks interesting but wanted to check if this will be released or was this project canceled since not much interest with diretta in us? 
thanks

Hi! Datka,

 

We are delighted to announced that New AfterDark. Project ClayX Rosanna Diretta Network Bridge Edition is developed after few years. 

 

• This Diretta ASIO is fully tested to work for Roon / HQplayer and ASIO with Diretta Host Software. 
• AfterDark. Sound Tuning, optimised for Audiophile with Carbon Fiber Chassis.
• Giesemann OCXO Master Clock build in or Accepting External 10M Master Clock for Sound Optimisation. 
• Add on option to choose to use 5V DC external power supply or build in AfterDark. Black Modernize LPS
• More excitiment to comes with AfterDark. technicial support on settup with Softwares. 

Thanks for long waiting.

Mike

Hi Mike,

 

Yes, all existing AfterDark. Project ClayX Rosanna Network Bridge could be upgrade too. Since the Diretta license is CPU locked, the upgrade will require to send back the unit to us. 
 

In case of running Roon Server windows version, running Diretta is easy to configure: 

• Install a new AfterDark Diretta Host software at Windows
• Plug in the USB DAC to New Rossana Diretta Network Bridge 
• Your USB DAC will appears at the Diretta Host Software setting page as ASIO network player. 
• Roon will appear as ASIO audio card as Diretta Player 
• Roon is ready to play music

 

There will be update plans for existing Rosanna Network Bridge, due to different configuration.
 

The upgrade cost will included the purchase of full Diretta License + MPD Licence + modification cost on upgrade etc.

 

Thanks and have a nice day.

 

Best Regards,

Adrian
