Long USB cable recommendation

Hi all.

I'm looking for recommendations on a long (~6 meter) USB cable (a to b) to go from my iMac to an ifi Zen signature DAC. Would like to keep it reasonable (~$100.00) if possible. For context, I like to stream Qobuz from my Mac and while the ifi has bluetooth, the delivery of high-resolution audio exceeds the compressed size of Bluetooth audio. I also use the ifi from my CD changer. 

From what I understand 5m is typically the limit of USB and the longer the cable the more prone it is to RF interference. For additional context, I also have a Bluesound streamer that I run ethernet from my router to the device, but I'm constrained with using BluOS, which I'm not a fan of. I guess Qobuz is still working on a connect feature to stream directly from their app but not sure on the timeline.

Thanks very much in advance !
