I made a few tests on volume, etc. The Z3 can handle moderate volume but I would get a unit with more power (it is 60 watts) if it is used other than the home. I got a little distortion with high volume on some instruments. I turned the volume all the way up on the Z3 to make this happen which I would not normally do. I set it just above the KN sound and the best way I can describe it is that is adds a different brilliance to the KN sound. You know when it is on. Nice clean sound. Hope this helps. Don
