Most of the profiles I use are profiled with a V30, or just sound great through a V30 loaded cab...I bought the Kemper cab (..has the Kone..what else would it have??) thinking I wanted all of these different speaker type options, but nope, I like 1 or 2 maybe, so I don't need it. I hear it sounding pretty good for different types of cleans, but for the modern hi-gain stuff, either one of my V30 cabs already sound great (..of course I turn the "Cab" sim button off to monitor.) Again, the profuiles I use are profiled with V-30 or OS Recto V30 cab, so for when I need to be loud and have the air moving, I just plug my Powerhead into one of those cabs, still use the main outs for PA or recording. The Kone/cab just isn't for me. Love the Powerhead tho : )
I fully understand what you're saying. When I got my Kemper, I assumed that I wanted amp x for clean, amp y for crunch and amp z for lead. Then a few others for certain sections.
I've enjoyed the journey of finding what profiles produce my preferred sounds and the ability to try new ones whenever I get bored but like you, my preferred sounds aren't all that different and don't require a number of different speakers to produce when one decent one will do.
