What is the DIRETTA

Diretta is a unique, different from the rest, protocol, which was originally developed by Japanese company MegaTech Electronics to improve sound quality for Hi‐End Audio equipment.

Diretta uses a software approach to reduce noise and inrush current during data transmission. When exchanging music data between a player and a server, the data processing is performed in such a way that the work of the CPU on the player side can be minimized and evened. This data is transmitted in short packages through regular and short periods that give significant improvement of sound quality.

This gives a huge advantage in sound quality over standard transmission protocols, such as DLNA, UPnP, or OpenHome.

Noise can be reduced by continuously sending a small amount of data rather than processing a large amount of data intermittently. DIRETTA ON RMP-UB1 reduces the impact of digital signal processing on analog signals, mainly in DAC devices, by averaging the data sent to the USB DAC. This improves the dynamic SN of the system, the original timbre expression emerges.

What do you need to get started with Constellation CAT?

1) Constellation CAT
2) DAC
3) Internet Connection
4) Android/Ipad Tablet or Phone
5) USB/SPDIF Cable

6) Roon, Jriver, Jplay or Audirvana subscription

Why several boxes?

We had tested all the possibilities and this solution was the most efficient. We are talking about performance without compromise, 
separating the computer parts from the power supply is
the best solution to fight against EMI pollution and noise. 

This is necessary to achieve the ultimate digital sound reproduction.

What’s the best way to connect your CAT ? ( Direct to USB DAC ..or via LAN) 


USB is the best choice to connect any Constellation CAT to your DAC and LAN if you are using Diretta Protocol). 

Why no Crystal Oscillators (TCXO, OCXO...) in our audio servers?

After several years of research, testing and listening sessions, we found that the addition of exotic clocks in the CAT removes all the 'emotion" of the music. If we make a direct comparaison, the listening experience would be more digital than analog like.

We pay particular attention to the true nature of the data, that's why our "clockless" solution remains the best in our experience.
