So played with Kemper + Fryette PS-2 + Kabinet.
Thoughts:
Fender amps / Vox amps with imprints (Jen P12R, Jen C12N Ceramic) sound definitely amp-in-the -roomish (Kemper Cone and Monitor Cab Off selected in OUTPUT menu). This I could not get with Yamaha DXR10.
High gain amps... this is tough to say. With "Kemper Cone" and "Monitor Cab Off" selected in OUTPUT menu I could not hear amp in the room so much (I heard it maybe once in guitar shop...) - well it was maybe there, when I set VOLUME on PS-2 to noon, but then my neighbours have to like metal music as well. But I don't find as much distinction between imprints, as it is on cleaner rigs.
I will compare once again with DXR10, but on cleaner profiles it sounds flat.
