I'm interested in hearing about other people's experience with the Kemper Power units used with real guitar cabs. I've had a PowerRack for a few years now, and one thing that has always bugged me is that, when I create a direct amp profile (no cab engaged), I hear a very good rendition of the amp sound into a guitar cabinet. However, as soon as I add a cabinet to the direct profile, the 'cab in the room' sound changes drastically (yes, 'Monitor Cab Off' is engaged here). For reference, I play primarily high gain sounds (Mesa Dual Rec, PV 5150, etc.).
As soon as I add a cabinet IR to the Rig, the real cabinet in the room starts to sound phase-y in the low end and is very boomy - even when I click off the cabinet block. It also loses a lot of the 'sizzle' that the direct profile had when played through the real cabinet. Is there something that happens when a cabinet is first added to a direct profile that noticeably alters the monitor output to a cabinet? Does anyone else notice this? I quit using this thing live for a while because of this effect. I'm considering keeping the Direct profiles as-is and just adding an IR pedal after the Main output, which seems kinda ridiculous, but would solve this issue...
It seems to me that the cabinet is being added to the rig, then 'removed' imperfectly for the Monitor output. If this is the case, it'd be nice if you had the option to just tack the IR onto the Main Output only.
Things I've tried with no improvement:
(1) Merged Profile vs. just copying an IR into a direct profile
(2) Pure Cab is OFF
(3) System reset
