Reviews
As I have a KVM switch with a very noisy signal chain as my USB, I hoped this would improve the quality into my Topping D90 DAC. Boy did it make a big difference. If it made half the difference it did I would have been happy with the purchase, so count me as VERY happy with this purchase.
I’ve integrated the Laiv Harmony µDDC into a highly optimized system built around the Gustard R26 DAC, and I can confidently say: this was the missing piece.
Before Laiv, I had already invested in high-end components, clean power (NCF filters, linear PSU), mechanical isolation, and careful fuse tuning (HiFi-Tuning Supreme³). Still, when I added the µDDC and connected it via I²S, the sound took a huge leap forward. Backgrounds became blacker, instrument decay more natural, and spatial precision reached another level. Compared to direct LAN or coax from my streamer (WiiM Pro), the improvement with Laiv was not subtle—it was decisive.
I now run the R26 exclusively in NOS mode because the input from the Laiv is so clean and stable that it lets the DAC perform at its absolute best. The soundstage is wide, tall, and deep. Music feels unforced and lifelike. This is the first time my system sounds truly high-end from end to end.
The build quality is excellent, and setup was plug & play. I also upgraded the HDMI (I²S) connection to AudioQuest Vodka 48, which unlocked even more spatial realism. The Laiv Harmony µDDC has outperformed even what I had expected from the Volumio Rivo+, and it pairs beautifully with the Gustard R26.
Highly recommended for anyone serious about digital playback.
I really enjoyed the µDAC when I entered into my system. I was just curious if this µDDC would add anything. It did. To me the changes are small but they are there. Everything a little bit more open, clearer, just a great sound. This will complete my system from an electronics stand point. Maybe a subwoofer upgrade down the line would be the cherry on top. Like the other stuff I purchases through LAIV, everything is put together so nicely. This company has it going, I hope they keep it up.
