Hi all,

Thanks for reading my post. I recently upgraded from Logitech speakers to Edifier R1280DBs and added an iFi ZEN Air DAC via USB on Windows 10. Overall, sound quality is better, but now I’m hearing distortion across basically the entire frequency range for many songs.

Some tracks sound fine, others grainy or harsh. Interestingly, Logitech speakers seemingly had no such issues (or were they just masked?) , so it’s odd that higher-fidelity gear brings this. Could it be the DAC?

I’ve tried Windows DAC settings (no enhancements, exclusive mode, Foobar2000 via WASAPI—though my Foobar test may not have been perfect), but the problem persists. Time is critical, as I may need to return one or both components if they’re defective.

Anyone else ever had or heard of similar issues? Should I consider a technician-level diagnosis, or is there something else I should check first?

Thanks!
David, near Barcelona, Spain
