I was just about to pull the trigger on a pair of Matrix CFR12s, but now we all know the Kemper Kabinet is coming.
However, it's still in development and we may not see it till the second half of 2018.
Thought it would be neat to check out what cabinets everyone's using till then.
Here's my cabinet of choice, a Mesa Boogie Thiele with an EVM12L speaker in there.
It isn't the lightest cab, but reproduction of Kemper tones is quite good and it can make your pants flap.
I mainly use a bluguitar Fatcab. Second is my Mesa Thile (C90 speaker)
Mission i/o
sambrox I like it a lot. Did some testing with NanoCab, Twincab, some Palmer with V30, some DV Mark Cabs. To be honest I did not make a direct comparison with my other cabs. But everytime I use it (live) as a monitor for guitar, I really like it. 
And I have an Amp1 as well... It's my powered backup... Looper Kit and Remote1 as well.
Even though I have the powered head, I ended up going with a DXR-10, partly for the love it gets here and partly because it's smaller than most of the single 12 cabs. Been very happy with it so I understand the love.
I don't use a cab much but when I need to I currently just use one of my Mesa Thiele EVM12L cabs.
