I use SMSL SA300 in desktop nearfield setup paired with two Anthony Gallo Nucleus Micro speakers and REL Tzero sub.
Crisp clear sound, nice stereo definition.
Although SMSL SA300 is packed in small chassis, it has enough power to push speakers and fill 20 m2 room with great sound without noticeable quality loss on high volumes.
Connection to SMSL SA300 is solely via Bluetooth from Mac. Works flawlessly, no drops, always reconnects automatically.
Overall, I’m very satisfied with it and would definitely recommend it.
