Constellation Reference

The Constellation Music Server is built with the best computer parts in the market to let you enjoy and feel your music as never before! Including High-End components, internal wires, fully optimized OS and a unique dedicated linear power supply. 

This server is equiped with a Intel CPU with 6 core, 12 Threads and 16 GB RAM industrial custom modules for best latency and data transfer. Clock-less (No TCXO, OCXO...), Fanless design, no noise, the OS part is a custom Windows heavily tweaked to reach an unprecedented level of performance. Every detail is kept to reach a top end musicality. Combined with our Ultra Linear Power Supply wich will never fall with is 154.000uF of capacitors. No ground choke are used because it provides dull and less dynamic sound This help to provide a good soundstage accuracy, micro and macro details, better headroom and very natural tones. ARTPC (Audio Real Time Process Control) manages all processes in real time and gives you a Roon experience you've never heard before. 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.
