So you found a VST that sounds as good as a Kemper? Whats the name of this marvel? If its from Bias then yes it sounds good to me too but doesn't come anywhere near the tones in my KPA. As Always YMMV.
Lots of VST's out there aside from BIAS. I'd actually put BIAS on the lower end of the scale from what I've heard and my experience. It's not terrible, but I've heard "better".
One interesting note at the Neural DSP booth at last years NAMM, they had the Nameless Suite and the Fortin Meshuggah amp it was modeled after, and they would switch back and forth while you were wearing headphones. Honestly, I heard no difference. I hear more subtle differences when going back and forth between the Kemper and its source in videos and comparisons. Still impressive, but the Neural test was a dead ringer. VST's have come a looong way.
