Your IRs in the AX8 are of close-mic'ed speaker cabinets. It's going to be colored by the mic characteristic, room reflection/resonance, where the mic was placed in front of the speaker, etc. This is good and fine, the guitar sounds of most tunes are produced this way. This is referred to on the forums as a "mic'ed-amp" sound.
It's different than the sound of an amp&cab in the room with you. Many guitarists new to modelers get an amp modeler and an FRFR, and complain that it doesn't sound like an "amp-in-the-room." It sounds like a "mic'ed-amp."
Speaker simulation by the Powercab is an effort to get you the "amp in the room" sound. It plays a direct speaker sound, rather than a mic'ed up speaker sound.
Thanks. I have about $350 credit at GC.Maybe I'll give one a whirl.
