The Pandora is a vacuum tube based digital-to-analog converter with one USB and three SPDIF inputs.

 Signature offers true native DSD 1x and 2x functionality over USB and 1x DSD over SPDIF (AES/EBU, RCA Coax and Toslink). The entire DSP processing section is replaced. The new section includes an advanced Xilinx gate-array which allows the DSP to be completely bypassed for pure DSD 1x and 2x operation. No alteration of DSD data occurs. Many DACs in the market that claim to play DSD actually convert the data to PCM and thereby completely lose the purpose of DSD operation.

Vishay Z-Foil Resistors
In addition to the DSP processing section, an entirely new analog board is installed. This new analog board also allows DSD data to pass directly to the DAC, a Burr-Brown PCM1792A running in pure differential mode. Extremely low noise, high linearity Vishay Z-foil audio resistors are utilized in the critical current-to-voltage conversion stage.

Dynamicaps
As in all Saturn Signature products, critical coupling capacitors are replaced with Dynamicaps from Peter Moncrief. Four are installed between the vacuum-tube gain stage and output stage, all in full differential mode. These provide increased resolution, less grain, greater high-frequency extension and naturalness, all while maintaining the basic strengths of Romulus’ tonal balance. The eight 2uF output capacitors are replaced with 4uF Dynamicaps which provide greater resolution in addition to improved bass definition, drive and dynamics.

HRS Couplers
The four standard rubber feet are replaced with Harmonic Resolutions Systems’ Nimbus Couplers specially made for Aesthetix. This change lowers the noise floor and adds more air and space.
