Princess Pasta Audio × Ricable: Capital Audiofest 2025 Atmos Showcase
A 5.2.4 Atmos System Featuring Ricable Magnus Cabling
Capital Audiofest 2025 marked a standout moment for Princess Pasta Audio and Ricable, as we partnered with SVS and Orchard Audio to demonstrate a meticulously assembled 5.2.4 Dolby Atmos theater system built around SVS’s Ultra Evolution loudspeakers and SB-5000 R|Evolution subwoofers. Power and dynamics came from Orchard Audio’s GaN-based Starkrimson amplifiers, with a Marantz AV processor handling decoding and system management.
Industry coverage highlighted the room for its dynamic headroom, clarity, and cinematic impact. What most of that coverage didn’t talk about directly—but listeners absolutely heard—was the role Ricable Magnus played in tying the system together.
Where Magnus Was Used in the System
To accurately represent Ricable’s engineering in a high-performance yet real-world Atmos setup, we deployed Magnus only where it mattered most for noise performance, spatial accuracy, and timing.
Speaker Cables — Magnus on L/C/R
The front soundstage — Left, Center, and Right Ultra Evolution speakers — were wired with Magnus Speaker Cables. This ensured tight transient behavior and stable impedance in the critical LCR channels where dialog, main musical information, and the majority of spatial anchoring happen.
Interconnects — Magnus XLR
All line-level connections from the Marantz AV processor to the Orchard Audio amplifiers used Magnus XLR interconnects. Consistent geometry, shielding, and dielectric control helped preserve microdetail, phase relationships, and timing — all key ingredients for precise Atmos object placement.
Power — Magnus Power Cables
Every Orchard Audio GaN amplifier in the room was powered with Magnus Power Cables. By stabilizing current delivery and reducing mains-borne noise, Magnus helped the Starkrimson amplifiers operate at their lowest practical noise floor and highest dynamic responsiveness.
RNR: Keeping Noise Out of the Signal Path
Ricable’s RNR (Ricable Noise Reduction) technology was especially relevant in this multi-channel environment. A 5.2.4 Atmos system is only as good as its noise performance and timing across all channels, so preventing noise from entering the signal path is as important as the electronics themselves.
RNR is engineered to minimize noise intrusion at three key points:
1. AC Mains → Amplifier
Magnus Power Cables help prevent high-frequency noise and switching artifacts riding on the AC mains from reaching the amplifiers. Cleaner incoming power means the Starkrimson GaN stages can operate closer to their theoretical performance, with less background hash and greater low-level resolution.
2. Processor → Amplifier (Line-Level)
On the line-level side, Magnus XLR interconnects use controlled geometry and multi-layer shielding to suppress ground-borne noise and RF/EMI interference. In an Atmos context, this directly supports more precise placement of objects in 3D space, because tiny timing and level cues are less likely to be masked by noise.
3. Amplifier → Speaker (Speaker-Level)
Even at speaker-level, where signal voltages are high, noise can still manifest as subtle haze or loss of definition. Magnus Speaker Cables on the L/C/R channels help maintain stable impedance and reduce induced noise, allowing the front soundstage to lock in with greater focus and clarity.
Atmos Performance: Soundstage and Spatial Precision
The end result in Room 628 was an Atmos system that didn’t just play loud; it played with remarkable spatial precision. Listeners consistently commented on:
- Soundstage stability across the L/C/R, even during complex pans and effects.
- Precise reproduction of Atmos spatial information — flyovers, height cues, and subtle rear-channel activity retained their position and clarity.
- An ultra low noise playback system character, where quiet scenes stayed truly quiet and dynamic swings felt effortless rather than aggressive.
- Clean dialog anchoring on the Magnus-wired center channel, with minimal smearing or congestion.
In combination with the SVS Ultra Evolution loudspeakers, SB-5000 R|Evolution subwoofers, and Orchard Audio’s GaN Starkrimson amplifiers, Magnus cabling helped ensure that no part of the chain became the limiting factor in spatial resolution or dynamics.
Looking Forward
Capital Audiofest 2025 proved that multi-channel systems benefit as much from high-performance cabling as traditional two-channel setups — and in many ways, the demands of Atmos make noise control and timing even more critical.
For Princess Pasta Audio, this room was an ideal opportunity to show how Ricable Magnus integrates into a modern 5.2.4 theater: stabilizing power, protecting signal integrity, and supporting the precise spatial rendering that makes Atmos so compelling.
We’re already planning future multi-channel demonstrations that will go even deeper into measurement, system design, and cabling choices. In the meantime, if you’d like to explore Magnus for your own two-channel or Atmos system, get in touch with us at Princess Pasta Audio and we’ll help you choose a configuration that makes sense for your room and gear.
From cabling to processing, every part of a system contributes to what you hear.
