Some devices like the Line6 modellers will sometimes not complete updates successfully using USB leads that have worked fine for other purposes. I had some issues of this nature and there were quite a few others who also had them and finding a better quality lead worked for me. Some leads work fine for power but not so well for large contiguous chunks of data at USB 3 speeds.

I am having the same issue. Windows 10, RM Version 3.2.72.17272, Release 8.7.1.36318.
Profiler is sometimes found by RM but the connection is is eventually lost within a few minutes. Multiple reboots of PC and Toaster, Windows updated, RM uninstalled/reinstalled, driver uninstalled/reinstalled. Nothing resolves the intermittent connection. This is a new 'feature' for me.
I would definitely trying substituting another USB lead and maybe a different port on the PC to make sure it is not a connection issue. Usually, if the software configuration is messed up then the KPA will not be recognised at all (until you do some uninstalls and clean out the various files in the OS and then reinstall RM). Some of these devices are pretty fussy when it comes to USB leads.

Just a note on the technicalities:
Level is an objective measure - signal voltage, sound pressure - and you measure it in dB relative to some agreed standard - eg dBu, dBV.
Loudness is a subjective experience - how the sound iteracts with your perceptual apparatus and nervous system - and is measured in phons.
https://en.wikipedia.org/wiki/Phon
If I say something is louder, that is analogous to me saying it tastes salty to me. You can't argue with me about my perception. You can only say - well, hmmph, it doesn't taste salty to me. We may not agree but neither of us are necessarily incorrect.

This is not exactly true, as mentioned above.
Quiet Profiles are not a problem.
And.. it is not possible to create quiet or loud Profiles. Every Profile is set to a unity level during the Profiling process.
The user has no influence to that whatsoever.
I was describing my experience with some profile sets. So I am trying to reconcile my experience with what you are saying here.
By unity do you mean unity gain over the input level? Or unity as in a standard RMS or peak volume level?
I have many profiles and some are much louder than others. It is possible to boost the level of a quieter profile in the parameters of the profile as I described and I have done this and the result is a louder profile, not clipping. So clearly, the KPA has headroom to cope with boosting in this way. Some profiles may be boosted perhaps after profiling by vendors. Another possibility is that clean profiles are not as compressed as profiles taken at higher gain levels, so subjectively, they are louder even though at peak levels (eg in attack transients) may be more nearly similar in level.

That is true - lots of quieter profiles out there. You can boost the volume of overly quiet profiles in several ways. Eg - you can get into the amplifier parameters and boost the volume there and play with other parameters like compression if you need to. Save your edits and you can match the volume of profiles that are too quiet for you to the louder ones.
It seems quite common for professional profilers to do a profiling run with different gain levels on the amp they are profiling, starting with gain/volume pots down at 9 o'clock and gradually turning up for the progressively dirtier profiles. The result of profiling this way is loud dirty profiles and very much quieter clean profiles.
If you are setting up a Performance with a set like this, you will likely want to boost the volume of the quiet clean profiles to better balance the levels.

I just updated to 3.2.72 - no information whatsoever about what this update is doing. Some release notes would be helpful. It worked for a very long time in the background before reopening. Seems OK after a restart or two.

Stomp section supports the FX loop but it is strictly mono there. Stereo FX loop (mono out, stereo return) is an option only in the post amp FX section. You need first to pick the "FX loop" in the FX menu for the location you are choosing - just as you would pick a compressor of drive effect. Then, once the wiring is set up, the FX loop will only be active when it is switched on.

A Strymon Volante is probably the best bet as far as getting full control over panning and feedback and 4 heads etc.

closest I've gotten has been with two delays back to back
Two dual delays would give you the equivalent of four heads on the echorec drum. Try playing around with the deeper parameters to try to match the tone. Echorec has a pretty short max delay - Gilmour uses 310 msec a lot because that was what his were capable of, some are shorter.
Check it out here.

Just scored a laptop in the local thrift store. Intel I5 chip, 8 Gb RAM, 220 Gb SSD (!). 45 euro. It has a Windows 7 sticker on it. It ran W7, W8, skipW9, now W10 and without a doubt it will run W11. The old standby Kemper is still up to date.
Check out the hardware requirements for Win 11. It may not unless you have a hack to get around M$. All the same an excellent score.

SPDIF is a good way to go.
Another option is to put a DI in front of the KPA - one that can put an unprocessed signal into the KPA and send a DI signal out to your audio interface. The IK Multimedia AXE I/O or the new smaller AXE Solo would be a high quality DI/interface option for guitarists with input impedance options and the output for reamping etc.
Most audio interfaces without discrete HiZ input circuitry are actually not great for guitar. Even RME HiZ instrument inputs are less than ideal. Dedicated discrete guitar inputs - which are found in the better modelers (eg Helix, HX Stomp etc and of course the KPA) do the job properly as do some of the more guitar oriented audio interfaces.

Perhaps the OP could do us all a solid and edit the title of this thread to make it clear we are discussing OS 8.7x.

Tone Junkie have quite a diversity of AC30 packs, different models and vintages, some profiles with Silver Bells, Alnico Blues and others drivers. As some other posters pointed out, the AC30 class A design has been widely emulated by boutique makers so Morgan, Matchless etc have excellent amps in this style to check out.
These have all been widely profiled by TJ, Selah Sounds, TAF, Mattfig and MBritt to name some of the more prominent vendors. Another vote for Brian Carl who has done some really nice Morgan profiles and the fantastic Morgan profiles on rig exchange are absolutely golden.

The circuit through a speaker or speaker box is a closed loop. Not the same as an active device.
Does the OX accept line inputs? The Boss WAZA TAE does.
You are not capturing new information by boosting the output signal from a Kemper through its clean Class D amp. You are just getting the signal on the line outs boosted to much higher levels - which you would then attenuate to line level with another device. Pointless.
-
If you can get it fixed as per the recommendations from the other posters, then that could be the best solution. The SD Powerstage 700 is an excellent unit and is stereo to boot. Makes a great alternative.

Have you had a fool around with the Directivity and the Bass Boost parameters when you have cabinet off enabled?
Guitar speakers - regular ones and the Kone - beam treble. You usually listen to them off axis so that they are not so bright but if you listen to them square on axis (ie listen from a position right in front of the speaker centre) - as you might for a studio monitor - you get an excessively bright sound unlike the sound you would hear with your cab on the stage/floor and off to one side. Sound familiar?
The directivity control allows you to compensate for this.

2x16 in parallel for 8 ohms is a good choice IMO. 2x8 is good if you want the option to wire in stereo/mono. You can run an 8 Ohm cab off just about any amp - 4 and 16 Ohm cabs can create more issues unless you are combining more than one of them.
You can get a jack plate which allows you to run in stereo/parallel or series from amplified parts for example
https://www.amplifiedparts.com…plug-and-play-mono-stereo. I used one with a pair of Kones in a 2x12 and the full wiring loom is there on the plate already with no need to solder if you prefer not to.

Class D amps are cleaner at lower levels. They distort more in not necessarily agreeable ways as they are driven harder. You will have more clean headroom at 4 Ohms. Whether this will matter to you in practice is another matter.
You can protect yourself from blowing up the cab by restricting the output power for the monitor out in the Output section. A 10 dB reduction there gives 60 watts instead of 600. Still plenty loud.

The Powerhead would work better with 2 x 8 Ohms in parallel for a total of 4 Ohms. Just mind the gain as you have 600 watts driving speakers with 120 watts of power handling.
If you want to be able to use a tube amp - eg a Marshall head - to drive the cab you would be better to go with 2 x 8 Ohm in series for 16 Ohm.
