From reading around, the SMSL SU-9 Pro seems to have my preferred neutral sound signature with airy soundstage, whereas the Ultra model has a warm sound signature with a limited soundstage.
However, there's one review of the Ultra model that references its uniquely black background, which I'd love to try.

And so I was wondering if the SU-9 Pro model also shares this same black background, or if it's unique to the SU-9 Ultra. The Pro model is advertised as featuring the ES9039MPRO dac chip with 11 OPA-1612A op-amps, whereas the Ultra model has the AK4191 + AK4499EX combo.
I'm trying to get a desktop DAC with no audible noise floor for sensitive iems. I plan to pair it with the Topping L70.

The spacing between instruments and vocals is not just spacious; it’s a void painted in obsidian, offering a blackness that lets each note emerge with crystalline precision. This DAC is the maestro of silence, where the absence of sound becomes as defining as the notes themselves.
