The Orpheus Labs Philosophy
Formed in 2001, Orpheus Labs is an offshoot of Anagram Technologies, known for its high-quality Digital Signal Processing (DSP) products. Anagram’s ATF algorithm, designed to eliminate jitter while minimizing time smear, was critical for Orpheus’ products.
Orpheus Labs is defined by principles that focus on:
Swiss Precision: State-of-the-art timing and mechanical engineering go into the construction of each product.
Proprietary Upsampling: Anagram ATF algorithm provides supreme digital filtering and reconstruction of the original signal.
Modular Design: To maintain optimum performance, Orpheus DACs spatially decouple power supplies, clocking, and the various analog stages for better isolation.
Adequate, Clear Audio: The Orpheus product line is specifically designed to achieve accuracy without adding any unnecessary warmth or color to the reproduction.
These guiding principles serve as the basis for achieving some of the industry’s most advanced and effortlessly beautiful DACs ever made.
Top of The Line Orpheus Labs DAC Models
The Orpheus Labs DAC model range includes multiple variants, all of which showcase the company’s relentless pursuit of precision and clarity in Digital to Audio Conversion (DAC). Highlighted models are the Heritage DAC, Orpheus One, and Orpheus Zero. Let’s dive into the details.
- Orpheus Heritage DAC (High-End Reference DAC)
The Heritage is Orpheus Labs’ flagship product and targets audiophiles looking for the highest possible fidelity in reproduction. It features Anagram’s latest developments in DSP, along with a separate discrete analog output stage.
Important Details:
Anagram ATF 24/192 Upsampling: Removes pre- and post-ringing issues, increasing naturalness and accuracy within the reproduction.
Dual Mono Design: Enhanced channel isolation provides a more realistic soundstage. Each channel is processed in its section of the circuitry.
Clean Power Supply Unit: Guards against fluctuations in noise, resulting in a quieter background and cleaner sound.
Performance & Sound: The Heritage DAC is best known for its high spatial resolution and instrument and vocal imaging. It does not artificially exaggerate detail, which keeps the tonal balance neutral and feels most appropriate for classical, jazz, and live recordings. Some users praised its audience reproduction features in concert recordings detailing audience sounds in a vivid and realistic way.
System Synergy: The Heritage DAC has its peak performance with high-resolution sources like high bitrate PCM or DSD. It also does well when combined with high-end linear power supplies and amplifiers.
- Orpheus One (and One Special Edition)
Orpheus One was among the first DACs designed by Orpheus Labs. It utilized Anagram’s ATF upsampling for 24-bit/192kHz conversion. The design has since evolved with the Special Edition (O1SE), which used new parts for better performance.
Key Features:
SHARC DSP Processor – Processes ATF upsampling with 40-bit floating point calculations as a high-efficiency supercharged engine.
Wolfson WM8740 DAC Chip (in earlier models) – It’s smooth, analog-like sound signature makes it an industry favorite.
Modular Inputs – Feature AES/EBU and S/PDIF inputs as well as USB in later versions, offering variety for different configurations.
Legacy & Comparisons: While the O1SE has been compared to other high-end DACs, like those from Esoteric and dCS, it still offers similar resolution for a lower price. The Heritage DAC was received favorably for its more dynamic performance; however, some users preferred the O1SE for its warmer midrange.
- Orpheus Zero (CD Player with Built-In DAC)
Although primarily a CD transport, the Orpheus Zero features the well regarded Wolfson WM8740 DAC. It has received accolades as a result of its smooth, analog-like sound.
Key Features:
Top Loading CD Mechanism:
Incorporates a Philips CD Pro drive that has proven to be dependable in disc reading and long life.
Fixed Output Level: Avoids unnecessary processing by allowing output to connect directly to the preamp.
Switchable Absolute Phase: Rearranges phase inversion for users, allowing for precision and sound for accuracy.
Performance: Sound reproduction from Orpheus Zero is crispy and clean while maintaining high details. Several users reported better results when using the unit as a CD transport unit with an external DAC.
Technology Behind Orpheus Labs DACs
Orpheus Labs DACs combine several of these factors, technologies advanced as a contributing reason to outstanding performance.
- Anagram Adaptive Time Filtering (ATF)
The ATF upsampling algorithm is one of Orpheus’s most important inventions and provides the smoothest possible temporal reconstruction of digital signals, removing blurring. Unlike conventional oversampling interpolative filters which cause harshness, ATF maintains fidelity to the original recording.
- CleverClox Jitter Reduction
CleverClox jitter elimination technology allows Orpheus DACs to reproduce their master clock and eliminates dependency on the source clock, greatly lessening jitter. The sound reproduced is cleaner and more precise, with less digital noise.
- Dual-Mono & Fully Balanced Design
The dual-mono architecture of Orpheus DACs has independently regulated power supplies for left and right channels which increases the separation between the channels which improves stereo imaging while reducing distortion. Fully balanced design meets clean output without added noise and distortion ensuring high quality audio reproduction.
Real-World Experience & Customer Thoughts
Strengths:
Unrivalled Transparency – Orpheus DACs provides a truthful picture of music, revealing previously hidden details in well-recorded tracks.
Excellent Soundstage Depth – Instruments are placed effortlessly within the three-dimensional space,e extending the depth of the listening experience.
Dynamic and Effortless – Orpheus DACs effortlessly reproduce complex musical sections like orchestral pieces without introducing distortion.
Considerations:
System Matching – High-resolution sources and resolving amplifiers are required for optimal performance of Orpheus DACs.
Price – Even used Orpheus DACs retain considerable value in the market which makes them a costly investment. Nevertheless, their quality effectively safeguards the expenditure for serious audiophiles.
Who Should Think About Buying an Orpheus Labs DAC?
Orpheus Labs DACs are crafted for audiophiles who center precision, timing, and the spatial characteristics of sound reproduction in their systems. These DACs suit users who:
- Prefer devices that ‘vanish’ within the system, leaving only the music.
- Value highly live recordings, classical repertoire, and acoustic jazz.
Desire a final DAC that will endure and deliver excellent performance for years to come.
For budget-constrained users, the Orpheus Zero or even an Ex-Demo Orpheus One provides a glimpse into Orpheus’ Swiss engineering finesse at comparatively lower costs. The Heritage DAC, however, remains the ultimate pick for the most demanding listeners who seek reference-level performance.
