The KPA and a great profile via a small computer speaker does not sound this great.
The feel of a real guitar amp speaker is very different because of many reasons - one is speaker size and the amount of air moved by the large speaker.
I was never really happy with small size near field monitors - and did not like the sound of most PA speakers as well.
So what is in (most) guitar cabinets?
12 inch speaker(s)
Since I use two active monitors with 12" speakers all sounds - and feels - SO much better.
What is your experence?
