Thank you very much for your answer Eric! It is always an honor for me to be able to speak with you directly. The "problem" is not in the amp block, that is perfectly emulated and I love it! The problem is between the interaction between the amp block and Legged cabinet system emulation (cabinet dimensions + speaker model), that interaction is what makes the difference and then After more than 1 year of testing I managed to solve it! The best thing, as I always say, is to try it, in misleading words or videos you don't feel or hear that difference, you have to play it yourself in some "FRFR" or PA. Is there any way I can share my work with you? I'll send it to you by email or whatever you tell me. It would be a pleasure.Might want to give this a read.
Public consensus is that, regardless of whether Helix's amps sound "better" or not, they are still the most accurate, at least to the specific amps we modeled. This is because Line 6 is the only hardware company (except for maybe UA and... Strymon?) that straight brute force models from the subcomponent up. Most other companies build from a schematic (which may be inaccurate!) with DSP LEGOs and often don't even have the real amp to compare against. If our amps weren't accurate, then countless double-blind A/B/X tests with golden ear engineers and session musicians would prove this out. In this particular case, the playback system is identical—a real cab—and in a few cases, we can pass null tests against the real thing. If another company applies some secret sauce to compensate for ""FRFR"" use, their amps are by definition LESS accurate to the original amp. For example, one company cuts the lows going into the amp, boosts lows coming out of the amp, and sometimes inserts audio compression to exaggerate sag. Whether that sounds good or not, it is NOT accurate—it's applying studio production trickery to fool rubes into believing it's more accurate.
Again, not saying our amps sound or feel objectively better—only that they are nigh identical in sound and feel to the original amps we modeled. Because unlike most other companies, we maintain the real amps in our building and constantly compare them.
