CONSTELLATION Masterpiece
The "ULTIMATE DIGITAL TRANSPORT"
The Constellation Masterpiece Music Server is built with the best computer parts in the market to let you enjoy and feel your music as never before! It is our flagship model including High-End components, internal wires, fully optimized OS and a unique PSU topology and distributed regulation.
This server is equiped with a Intel CPU with 24 core/32 Threads and 32 GB RAM modules for best latency and data transfer.
Clock-less design (No TCXO, OCXO...), no fans, no noise, the OS part is a custom Windows heavily tweaked to reach the lowest latency possible. Every detail is kept to reach a top end musicality. Designed to keep system noise levels as low as possible the dual linear power supply and special shielding prevent the transmission of digital noise to the DAC, ensuring the best possible sound reproduction. Our Ultra Linear Power Supply wich will never fall with is 890.000uF of capacitors and an oversized dual 500VA pure silver transformer. This server consist of 3 frames, 1 server unit, 1 precision unit and 1 power supply unit. This help to provide the best soundstage accuracy, micro and macro details with better headroom and very natural tones. It also improves depth, resolution with a blacker background. Pachanko ARTPC (Audio Real Time Process Control) manages all processes in real time and gives you a Roon or Audirvana experience you've never heard before. Combined with the Diretta Protocol you have clearly the best Digital Transport on the market! We are confident that you will love it.
Pachanko “O Core” Transformers
Hand-crafting with passion the heart of our powered Audio components
Pachanko Labs seek perfection in our product performance.
We produce by hand each and every Toroidal O-Core Transformer that powers our units.
We believe the transformer to be the heart of our powered products. We want pure and clean current to flow through our units.
Rather than basing our products around off-the-shelf solutions we take pride in custom manufacturing all our special transformer units.
We manufacture and install our Audio-O-Tec Toroidal O-Core Transformers (ATOC) in our Internally Powered or multi-unit products.
Our Constellation Reference, SE and Masterpiece Audio Transport series along with our Stellar and UPS power supply series all carry our ATOC transformers.
ATOC transformers have a ring appearance and a perfectly round core shape. This uniform design leads to minimal leakage current compared to other types of transformers (toroidal, “R”).
Our single-wire and hand-spun transformers guarantee uniform winding with the highest-purity copper or silver wiring and low DCR per turn.
ATOC transformers offer the lowest possible noise level and ensure the highest performance of Pachanko Audio components.
Built with care for your best audio experience.

Introducing a novel audio protocol designed to enhance high-fidelity sound quality. It takes a fundamentally different approach compared to existing protocols.
In the world of audio, several factors impact sound quality, and one significant factor is the interference caused by digital components. Typically, capacitors and inductors are used to reduce this interference and create low-pass filters to minimize unwanted digital noise.
However, even with these filters, some low-frequency fluctuations persist, unnoticed when observing voltage but detectable when examining electrical current. Eliminating these noises through electrical means is challenging.
Diretta's solution involves close coordination between a Host and a Target, using predictive data transmission at consistent intervals to stabilize power consumption and enhance audio player performance. This process is akin to USB synchronization but with the Host controlling the pace, eliminating the need for complex buffer and flow control systems. This allows for isolated connections like fiber optics and simplifies processes compared to protocols like UPnP and AES67.
To integrate the "Diretta" protocol as effectively as possible, we have developed ‘Flow’, which allows you to get the most of this technology. "Flow" maintains a constant flow of data without interruption with a perfect timing. The result is a natural, in-depth listening experience.
