PierM. In the case of Fractal Audio, there is absolutely no need to tune the amplifiers, because they already sound good, there is no need to look for good IRs, because they are already in the device in the amount of 2000! On Helix, if I need a good sound of an overloaded amplifier channel, I either need to tune for a very long time, or PAY ALREADY for the device PAYING FOR well-sounding presets and IRs.
What can you say about the fact that for many years Helix programmers have not been able to properly program the tuner? Many people complained about this, but they did not help them, but on the contrary, they threatened to be banned because people were telling the truth. Any inexpensive clothespin tuner works better and more accurately, but they don't want to hear it, fix it, preferring to delete objectionable reviews or threaten, perhaps as a joke, or perhaps not as a joke!
