Thanks for the feedback , and I'm not surprised.
Thing is, it's the generally warmer Ownhammer IRs that work best with the Helix.
It might be a different story if your setup was using irs in your DAW with a real amp / load box and line out to pc.
It's not always down to the quality or accuracy of the irs, but rather, which works best with the Helix which has a tendency towards brightness and fizz.
