Hello Grady,

Thank you for reaching out. Our full list of Audio USB converters can be found here.

However, please know that hearing a device "pop" on power up is often a result of the outputs being unmuted before the system's power rails have had a chance to settle. Usually this is the result of a capacitor somewhere in the signal path not being fully charged. It is recommended to wait for the supply rails to settle before applying output to the device.

Best,
Andrew
