Here is my initial take on the Snowsky Retro Nano:
The Snowsky Retro Nano instantly took me on a nostalgia trip. It looks just like my Soundwave toy from the 80s Transformers Autobots toy line—the cassette player robot with a tiny cassette tape in its chest that ejects and transforms into Lazerbeak a robot eagle and Rumble a robot that has jackhammers for hands and can create earthquake hehe the Retro Nano has that same compact, matchbox-sized form factor, and the resemblance is uncanny! But back to reality—this little device surprised me in ways I didn’t expect. As cartoony as it looks, it punches way above its weight, outperforming some dongles that cost twice or even three times as much.
Compared to the pricier FiiO KA15, the Retro Nano holds its own in sound quality and technical performance, sometimes even edging ahead in certain aspects. And when it comes to LDAC mode, it easily outshines the $180 FiiO UTWS5. The Retro Nano not only sounds better but also delivers a more stable signal with an impressive range up to 15 meters in clear line of sight. Unlike the UTWS5, which occasionally suffers from pops and crackles in LDAC mode, the Retro Nano runs flawlessly.
As you can see in my photos, I paired the Retro Nano in AptX HD mode with the FiiO TT13 turntable, and it had no problem driving my full-sized Sivga Anser over-ear headphones to loud volumes at just 60–70% output. That’s some serious power for such a tiny device.
Under the hood, it packs dual CS43131 DAC chips, which are known for their excellent clarity but can sometimes sound bright, cold, or artificial if not implemented well. However, Snowsky has tuned the Retro Nano beautifully—it leans more towards the warm, natural tonality of an AKM DAC rather than the sharper, analytical character that CS chips sometimes exhibit. It doesn’t sound overly bright or sterile; it just sounds right.
For something that looks like a toy, the Retro Nano is an absolute powerhouse. Stay tuned for my full review soon.
