I just added a SMSL SU-X to my ma352 today. It was only 1k and measures better than most other DACs so I said why not, if it’s a dud I didn’t risk too much money relatively speaking. Well, using the Node as a streamer, I got amazing performance out of it, and I say the sound quality increased at least over 20 percent than using the Node alone. I am running SF Olympica 2 speakers.
Also, I’m running XLR audio cables from Amazon, they made a significant improvement also. These no-name, cheap Chinese audio companies are seriously holding their own. This SMSL SU-X sounds better than a 4k Wandla set up , and the SU-X even has a tube mode. Using tube mode, with my integrated tube amp, and SF speakers, I am in total audio bliss now. So satisfied. Thank you SMSL for not ripping us off and giving us world class performance!
