Another question about the pop-sound. Will I notice it when using stuff like Spotify/Youtube/Netflix? Or to put it differently, can I put the driver to output the same sampling rate no matter what? Is this only an issue for people who want to deliberately use different samping rates or will it...

This one: https://www.ip-sa.com.pl/audio-p-1305.html is the old version, right? The NFB-11.28 is basically the new 2017-version of it. Other than better USB drivers, is there a fundamental difference, that warrants the price difference?

Hi, I'm planing to get a Sennheiser HD650 and looking for a decent AMP+DAC (mainly USB) for it. Please note that this will be my first "more expensive" audio setup, so I don't want to pay more than ~600€ for everything. * That leaves around 250-300 € for the DAC + AMP * I'll buy from the EU...
