I think his issue is that in the FRFR mode, the sound is not too bright - actually it's missing the high frequencies. I have the same issue too with my PC 'regular' 112 - the flat mode (while led on. should be FRFR) is not usable at all using helix LT with cabs/IRs (even tried without it). It just sounds still in it's carton box. Other speaker modes in the PC sounds good (with helix presets that don't use cabs/IRs).

What learning curve is there, on the powercab (standard, not plus)?! use flat mode with presets that uses cabs/IRs, all other speaker modes don't use cabs/IRs. the flat mode sounds muddy and distorted (with helix preset with cab/IRs) = not flat at all, as if I drive the helix through a smartphone speaker or as if the PC is still inside its' carton box.
