Anyway, I thought I should share the results of my experience with you all, it may help someone else shorten their path to tonal Nirvana with their Kemper. The A was designed 15 years ago with only low frequency applications in mind. The differences are hardly distinguishable in general. We’re talking pre-Armstrong here!
My bandmates have stopped complaining about the blanket-over-the-amp tone from my cab, another benefit of higher bandwidth. I was using a Weber Vintage speaker at the time in an old Lopoline 1X12 convertible cab, as well as some Carvin 2X12 cabs.
Hopefully this post iceppwer not upset too many Power Head fans, but I would like to post my observations about the Power Icepowed with the Icepower A amplifier and the Power Rack as well I assume, since they use the same power amplifier. It comes down to what is in there.

Take it as you will. Well, I LIKE having a cab behind or sometimes in front of me interacting with the guitar, and I like the traditional cab look.
Going through the main out direct to the PA sounded nice and sparkly all the time, but the cab sound was dark no matter what I did. There is actually no need to worry about the sound of a todays solid state amp.
I figured the issue was the speaker.

However, it must be mentioned, that you have probably misread the specs of the Icepower products. That will put it to rest. If I had known then what I know now, I would not have purchased the Powerhead, I would have just bought the unpowered version and used an external power amp with wider BW for driving a cab, as well as just biting the bullet and buying a good FRFR cab.
I went through several setups too before I fell in love with the same rig. That explained the more sparkly and open sound, it was getting close to the direct-through-PA tone I was experiencing. So all’s well that ends well. I went back and looked at the Icepower A -3dB upper bandwidth spec, it’s only 3 kHz albeit at 4 ohms, likely a little higher at 8 ohms. We supply the A. Therefore there was no need to go above 3khz. Thanks for the help!

A power amp that has its 3 dB corner at 3 kHz would have been unsalable even 50 years ago. Since I bought it, I have had many comments from fellow bandmates in the bands I have been in or am in regarding how dark the 0100a was from the cab, no high end. Kemper Profiler Forum Private forum Profiler related discussions. Every other doc shows a responce beyond icepoower or 30 kHz. When the ASP was designed a couple of years later, they thought that they would get more full range applications, so it was designed up to 20khz and everything since then and going forward is full bandwidth.
Ah, that makes sense. I was for certain not looking at the phase response, it was definitely the frequency response curve. I have purchased a KPA unpowered rack unit and intend to use that with the GTFX for live use, and I’ll use the toaster with the Quilter for rehearsals and recording. This is as shown on page 9 pf v1. Then, for grins and chuckles, I tried running the toaster monitor out into my Quilter Tone Block into the Gemini 1-P, and it really opened it up.
Also, are there any – 3dB BW measurements at 8 ohm loading for the A?
I would like to check and see if the typical -3dB bandwidth at 4 ohm loading value of 3 kHz, as given in the data sheet see highlighted line on page 5 of attachment is a correct value?
I suspect this is an error in their documentation.
Thanks for reaching out. Now if I could only play better Any errata sheets for the data sheet?
