Hi. I'd like to share my experience using Helix Native. I have the Helix Floor and been using my studio headphone to dial in my tone. Did the same for Helix Native i.e. using the same headphone but indeed it sounds fizzy, muddy, whatever you want to call it, certainly unpleasent and not the same tone as what I heard from the floor unit. Tried the exact same preset as the Floor unit and indeed it has a different tone. After gone through each setting, I found the solution! There is an "Input" level at the left of the "Host". Reduce the level from 0 dB to -18 dB. Thats it. You may want to increase the output level (right of "Main" meter) accordingly to complement the volume.
