About the 4705 Progression Gemini

The 4705 Progression Gemini DAC was launched by 47 Laboratory about 20 years ago with a unique concept of non-oversampling and no digital or analog filters, aiming to deliver a natural and direct sound that communicates the musician's intention. It features passive I/V conversion, the shortest signal path of 35mm among DACs, and uses the smallest number of parts possible. The DAC supports input sampling frequencies of 32 kHz, 44 kHz, and 48 kHz automatically, with a 16-bit digital converter and an output voltage of 2.1V. It has a single coaxial digital input and one pair of unbalanced RCA analog outputs. The unit measures 60mm x 162mm x 70mm. The design emphasizes simplicity and minimalism to achieve high sonic purity and microdynamic detail. It is often paired with the 47 Lab 4713 Flatfish CD player and powered by the 4799 Power Dumpty power supply for an elite CD playback system. The DAC is noted for its lively swiftness and ability to reveal delicate transient details, though it requires careful system matching due to its energy concentration at 22 kHz and lack of de-emphasis function. The 4705 Progression Gemini is considered a high-end, niche DAC with a price around .
