Zd3 vs jbl

I've been connecting to my older JBL home theater with my phone and thinking it sounded good enough. I upgraded my speakers and wanted newer tech to drive them. I compared the sound quality between the onboard DAC installed in the JBL and the Fosi ZD3. The fosi was a big improvement. I could hear the actual cymbal strikes, not just crashes distorting into the next crash. Deeper base too.

Gave new life to my 40 year old Polk speakers

After my original amp imploded I had let the speakers sit, but finally pulled the trigger on the ZD3 and 2 ZA3s. Back to listening and enjoying my music collection.

Exceed my expectations

I had a cheap Ebay DAC but my interest in sound pushed me to purchase the Fosi. My mind was already settled that I probably would not notice a difference in sound quality. But my wife and I immediately noticed a huge difference in the dynamics of sound that came from this unit. It looks beautiful with our sound system and I am now interested in testing some of their other products. They are definitely money well spent. To put it short, I was blown away with the difference.

Great value for money!

Easy to set up, easy to use. Sounds amazing...really natural sounding, just what i wanted. Only bummer is that i bought it from an importer in my country which was more expensive. Should have bought it directly from the Fosi Audio website instead.
