Thank you for responding. Are you sure the Pandora was not merely basting the music in the delicious caramel coating of tube sound?
Which DAC did you perceive to present the music with greater transparency and resolution?
With which DAC did you hear more details?
Which transport do you use with the Pandora?
Hi Ron,
I have listened to the Aesthetix Pandora many times at my local dealer with Jannus preamp, Atlas Signature Monoblocks and Vandersteen Model 7 Speakers. This DAC produces an analog-like midrange with body, bloom and air. There is minimal tube artifice. Treble is natural and non-fatiguing but not rolled off and bass has wonderful texture. Soundstage is as wide and deep as the recording.
There are two editions:
1) Pandora Signature - MSRP $9,000
True Native DSD
Romulus and Pandora Signature offer 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 (pictured above, click to enlarge). 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 (pictured above, click to enlarge). 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 (pictured above, click to enlarge).
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. (pictured above, click to enlarge).
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.
2) Pandora Eclipse (New) - MSRP $12,000
First phase: Internal changes start with .22uF / 600v Stealth coupling capacitors used between the gain stage and output stage. Four total of these exotic capacitors are used.
There are four 2uF / 400v coupling capacitors used in each channel of the output stage. In the Eclipse version, these are replaced with Stealth copper foil 4uF/400v, improving low frequency response.
Third phase: The main transformer is re-installed on isolation mounts. Harmonic Resolutions Systems' Nimbus Couplers specially made for Aesthetix replace the four rubber feet of standard units (as also found on our Signature version). The new power supply is installed with enhanced ventilation. Additional damping material is added to key chassis points.
Fourth phase: A single point ground system is used to ground the transformer cases as they are no longer electrically grounded to the chassis via physical contact due to their isolation mounts.
All the best,
Ken
