icepower 1000a ICEpower 1000A Class D 1000W digital amplifier digital amplifier module board
Ah, that makes sense. I was using a Weber Vintage speaker at the time in an old Lopoline 1X12 convertible cab, as well as some Carvin 2X12 cabs.
The A was designed 15 years ago with only low 10000a applications in mind. It sounds darned near just like the PA tone. That will put it to rest. Below is the exact communication from their rep, Paul Meister. 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. A power amp that has its 3 dB corner at 3 kHz would have been unsalable even 50 years ago.
Nice that you have found your tone.
Well, I LIKE having a cab behind or sometimes in front of me interacting with the guitar, and I like the traditional cab look. My intention was to use it as a standalone amplifier to drive a cab and eliminate my pedalboard and boat-anchor tube amp.
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. I was for certain not looking at the phase response, it was definitely the frequency response curve. 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 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. 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 sound was from the cab, no high end. My bandmates have stopped complaining about the blanket-over-the-amp tone from my cab, another benefit of higher bandwidth.
The differences are hardly distinguishable in general.

Icepower A Bandwidth – Profiler related discussions – Kemper Profiler Forum
We have never got a report in the past that our build in power amps attenuate the highs. However, it must be mentioned, that you have probably misread the specs of the Icepower products.
So all’s well that ends well. Every other doc shows a responce beyond 20 or 30 kHz. Kemper Profiler Forum Private forum Profiler related discussions. I figured the issue was the speaker.

Thanks for the help! I went through several setups too before I fell in love with the same rig. Hopefully this post will not upset too many Power Head fans, but I would like to post my observations about the Power Head with the Icepower A amplifier and the Power Rack as well I assume, since they use the same power amplifier. It is likely that you have looked up the phase responce graph, instead of the frequency responce.
This agrees with the 30 kHz value. It comes down to what is in there. We’re talking pre-Armstrong here!
I am wondering why there are so few Kemper users endorsing such a great product. The power amps go up to 30 kHz with an error of less that a dB, according to the icfpower. Therefore there was no need to go above 3khz.
Now if I could only play better Can you please tell me which one it is? 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. I haven’t wanted to open it up and look at what is inside, I’m afraid to void the warranty.
However, it doesn’t matter, since we obviously do not use the A, otherwise we would have communicated the W icepowef. Thanks for reaching out. I went back and looked at the Icepower A -3dB upper bandwidth spec, it’s only 3 kHz albeit at 4 iceepower, likely a little higher at 8 ohms. Take it as you will. This is as shown on page 9 pf v1.
It is not an error in the datasheet. There is actually no need to worry about the sound of a todays solid state amp. 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.
We supply the A. That explained the more sparkly and open sound, it was getting close to the direct-through-PA tone I was experiencing. It seems on the low side. I suspect this is an error in their documentation. Also, are there any – 3dB BW measurements at 8 ohm loading for the A?
