The SMSL SU-9n is a streamlined take on SMSL’s popular classic SU-9 DAC. The “n” version takes the core of what’s great about the bigger brother—clean audio, reliable performance—and removes some bells and whistles to hit a more accessible price point Read More
Let me start with my system. My best headphones are the Hifiman HE6se Ver. 2 and they are not the easiest to drive. The headphones were paired to the Drop AAA 789 and the Grace Balanced SDAC. I suspected that the Grace SDAC was the weak link in my audio chain and it turned out that I was right. The music came alive much more with the SMSL DAC with better bass response. I was questioning whether I needed more power to drive my headphones, but with this DAC (all in balanced mode), I think the power from the 789 is more than adequate. I find the SMSL SU9n to be a solid upgrade from my Grace SDAC. The improvement in sound quality was readily apparent. But keep in mind how this product might (or might not) integrate with your system.
