I’m trying to decide which one to get. I feel like SU-9 Pro has my preferred neutral sound signature with airy soundstage, whereas the Ultra is warmer. However, I read from another review that the Ultra model has a noteworthy “black background,” which is something I really want to try. Did you experience this “black background” on the Ultra model as well, and how would you compare it with the Pro model’s background? I’m trying to get a DAC/amp setup that’s compatible with sensitive IEMs. Thank you 🙏
