Ngoài những thừa kế giống với người tiền nhiệm trước như usb hỗ trợ 24bit/96kHz, build-in headamp HPA2,... DAC1 HDR còn bổ sung thêm tính năng đúng với gọi của nó HDR-VC (High Dynamic Range - Control Volumn) và Remote control.
Benchmark cũng thông báo đây là sản phẩm với số lượng có hạn sẽ được chính thức bán vào ngày 20 tháng 4 này với giá cũng "nhỉnh" hơn: $1895.

Performance Specifications:

• Digital Input Sample Rate Range: 28 to 195 kHz
• THD+N: -107 dB, 0.00045% (w/ -3 dBFS input)
• SNR - A-weighted: 116 dB (w/ 0 dBFS = +20 to +29 dBu)
• Maximum Amplitude of Jitter- Induced Sidebands
• Maximum Amplitude of AC line related hum & noise: < -126 dB
• Headphone amp output impedance: 0.01 Ω
• Headphone amp output-level range (@ 0 dBFS into 60-Ω load): 21 dB
• Headphone amp THD+N: -107 dB, 0.00045% (w/ -3 dBFS input)

Features:
• IR remote control with adjustable ‘Dim’ and ‘Soft-Mute’
• High-Dynamic Range Volume Control w/ custom-built, motor-driven Alps volume pot

• State-of-the-art LM4562 high-current, lowdistortion opamps in critical analog circuits
• Stereo outputs: XLR balanced, RCA unbalanced, HPA2™ headphone jacks
• Built-in HPA2™ headphone amplifier - 0-Ohm, high-output, two output jacks
• HPA2™ headphone amplifier hasselectable gain ranges to match headphone sensitivity
• Left-most headphone jack mutes XLR and RCA outputs (this feature is defeatable)
• On/Off button and rotary source selector
• “Calibrated/Variable” switch determines gain control for main analog outputs
• Internal trim-pots control gain of XLR and RCA outputs (in “Calibrated” mode)
• Selectable, low-impedance attenuators (0, 10, 20, or 30 db) on XLR outputs
