MSB Analog DAC vs DAC IV Plus ?

Hi,

Did anyone compared sonically these two MSB DACs?

Their specs are confusing for clear comparison.i.e. Analog DAC has two 35 bit D/A, single ended architectre and "custom" clock. DAC IV Plus has four (2nd generation) 24 bit D/A, balanced artictecture, and "Femto 140" clock.

Analog DAC has optional $3k PSU.... optional digital inputs at $1k each etc.

Thanks
