Aesthetix Pandora DAC
Aesthetix is proud to introduce the Pandora and Romulus. They join our Saturn Series, recognized around the world for outstanding performance, build quality, and user interface. High quality construction techniques include an all-aluminum chassis, stainless steel faraday cage to isolate digital sections, multiple power transformers in a stainless steel enclosure, and multiple regulation stages. These components raise the bar for all digital products and are the ideal match for our Janus and Calypso preamps, and Atlas power amplifiers.
Ultra Low Jitter USB and SPDIF
The Pandora is a vacuum tube based digital-to-analog converter with USB and three SPDIF inputs. USB runs in asynchronous mode, with an ultra-low jitter fixed-frequency crystal clock immediately adjacent to the DAC. It runs in user-selectable class 1 audio, up to 96KHz / 24 bit or class 2, up to 192KHz / 24 bit. SPDIF/AES inputs use unique technology that offers jitter performance on par with asynchronous USB and are also capable of up to 192KHz / 24 bit.
Vacuum Tube Analog Stages
The Aesthetix reputation for state-of-the-art analog stages is continued in the Pandora, which features a current-sourced differential vacuum tube amplifier (12AX7) being fed from the DAC. Differential amplifiers have the unique ability of rejecting “common mode” signals, particularly useful in digital audio products, where high speed clocks and other digital noise can disrupt the delicate analog circuitry. Following the first differential amplifier, the audio signal is fed to the output stage, another differential amplifier based on the 6DJ8 vacuum tube. Both Pandora and Romulus feature Rel-Cap polypropylene coupling capacitors and Roederstein metal film resistors.
High Resolution Volume Control (+$1,000)
An optional high resolution relay-based volume control may be added to either Pandora or Romulus, allowing them to directly drive a power amplifier, ideal for many systems. This special volume control operates partially in the digital domain (for small 1dB steps) and partially in the analog domain (6dB large steps), assuring uncompromising performance.
