Key Features
Defining characteristics
AMR DP-777 SE
Gemini Digital Engine®
Combines a High-Definition 32-bit DAC with a Classic 16-bit multibit DAC under FPGA and DSP control.
Organic Digital Algorithm
AMR’s SMART® filter technology addresses pre-ringing and post-ringing for a more natural digital presentation.
OptiSampleHD®
User-selectable modes preserve the original bit and sample rate through both High-Definition and Classic DAC paths.
Global Master Timing®
A quartz-driven clock system with over 28 million frequencies decouples DAC timing from incoming source jitter.
Intelligent Memory System®
Buffers complete audio samples to absorb incoming jitter and drift before stable reclocking.
NOS Valve Analogue Stage
A valve output stage completes the digital processor with AMR’s preferred single-ended analogue philosophy.
Two DAC paths. One digital processor.
The DP-777 SE uses separate High-Definition and Classic Multibit DAC paths, allowing HD recordings and CD-quality sources to be treated according to their native strengths.

Craftsmanship
Engineered for timing. Designed for musical ease.
The DP-777 SE uses FPGA/DSP digital architecture, custom timing systems, premium AMR-selected components, silver leaf capacitors, Oscon capacitors, gold-plated military-grade PCBs, Schottky rectifiers, and a NOS valve output stage to preserve the musical potential of digital sources.
HD precision. Classic multibit musicality.
The DP-777 SE gives high-resolution and CD-derived digital audio dedicated conversion paths instead of forcing one universal solution.

Receive.
Multiple digital inputs.
The DP-777 SE accepts XLR/BNC, RCA/Toslink S/PDIF, and asynchronous USB digital sources.

Output.
Single-ended valve philosophy.
The analogue stage follows AMR’s dual-mono, single-ended design preference for musical naturalness.
Technical Excellence
Two DAC engines. Advanced timing. Valve output.
The DP-777 SE supports 24/192 asynchronous USB, multiple S/PDIF interfaces, High-Definition and Classic Multibit operation modes, and NOS valve analogue amplification.
