1. Overview of the LampizatOr Poseidon DAC
The Poseidon was developed to bridge the gap between LampizatOr’s entry-level models and the top-tier Horizon DAC. It replaces 12 previous DAC models, including the Golden Gate and Pacific, consolidating the best features into a single, refined unit.
Design & Build
- Chassis: CNC-milled, available in Black Hole or Silver Sahara, with an optional copper top plate (“Duracell” look).
- Weight: 23 kg (55 lbs), housed in a custom flight case for protection.
- Display: OLED screen for input selection, volume control, and settings.
Digital Engine
- Engine 11X: Supports PCM up to 768kHz and DSD512, with ultra-low jitter and complete USB/i2S isolation.
- No silicon in the signal path – pure tube amplification after conversion.
Analog Stage
- Fully tube-based with zero op-amps or global feedback.
- Balanced & single-ended outputs (3V SE, 4.7V balanced).
- Integrated preamp functionality with a high-quality volume control
2. Key Features & Innovations
Poseidon stands out with several unique advancements:
1. Tube Complement
- Rectifier: 5U4G (stock), but it supports 274B, GZ34, 5AR4.
- Input Stage: 6N1P (Soviet military-grade tubes).
- Output Stage: 6J5 (stock), but compatible with 6V6, EL34, KT66.
2. Preamp Functionality
- Eliminates the need for a separate preamp, with high input impedance (470kΩ) and low output impedance (400Ω).
- It can drive solid-state or tube amplifiers without coloration.
3. Tube Rolling Flexibility
One of the biggest strengths of Poseidon is its extensive tube compatibility, which allows users to fine-tune the sound signature.
3. Best Tube Rolling Options for the Poseidon DAC
Tube rolling can significantly alter the sound—here are the best options:
A. Rectifier Tubes (Power Supply)
- Western Electric 274B a smooth, holographic soundstage, excellent dynamics.
- Takatsuki 274B – Ultra-detailed, extended highs, and tight bass.
- Mullard GZ34 – Warm, lush midrange, great for vocals.
- RCA 5U4G has a punchy bass, slightly more aggressive than WE274B.
B. Input Stage (6N1P Replacements)
- Telefunken ECC88 – Airy highs, precise imaging.
- Amperex 6922 – Rich midrange, musical tonality.
- Siemens E88CC – Analytical, great for classical music.
C. Output Stage (6J5 Replacements)
- Tung-Sol 6J5 – Warm, smooth, excellent for jazz.
- GEC L63 has fast transients, great for rock and electronic.
- KR Audio 6V6 – Big soundstage, dynamic impact.
- EL34 (with adapter): More power, fuller bass.
4. Sound Characteristics & Performance
The Poseidon is praised for its balanced yet engaging sound:
- Tonality: Natural, with no digital harshness.
- Soundstage: Expansive, with pinpoint imaging.
- Bass: Tight and controlled, with deep extension.
- Highs: Smooth but highly resolving.
Comparison to Other LampizatOr DACs
- Vs. Horizon: The Horizon offers 5-8% more refinement, but at double the price.
- Vs. Pacific: The Poseidon is more dynamic and detailed, while the Pacific has a softer, more romantic presentation
Conclusion
The LampizatOr Poseidon DAC is a masterpiece of tube-based digital conversion, offering reference-level performance at a more accessible price. Its flexible tube-rolling options allow users to tailor the sound to their preferences, making it one of the most versatile high-end DACs available.
For those seeking a blend of technical excellence and musicality, the Poseidon is a top-tier choice—whether used as a standalone DAC or a preamp-less system centerpiece.
