Tomic601, looks like you too can benefit by going direct from Pandora to poweramps to get ultimate resolution as Aesthetix points out below.
"An optional high resolution relay-based volume control may be added to either Pandora or Romulus, allowing the units to directly drive a power amplifier.
The Pandora and Romulus volume control prevents all resolution loss by operating partially in the digital domain for small 1dB steps and partially in the analog domain using relay-based switched resistors for large 6dB steps. Using this method, eighty-eight 1dB steps are created with zero loss of resolution."
