The ultra uses 4 pieces of opa1611 in the analog stage that seems to be DC coupled . An absolutely sota op-amp used, and no capacitor to degrade the sound.
The output impedance though rca out is very low, at 11 ohms. Perfect for driving poweramps.
It cant be much more transparent than that . I think this is a good thing in a preamp.
However , as my own review showed with the Rega dac - one might prefer some coloration later in the chain = lower SINAD .
I think that the digital preamp in ultra is absolutely sota soundwise - and using an external dac makes it free to use any colored dac of choice .
