I wanted to update on this rig build now that everything I ordered has arrived. The Fryette LX II power amp is very nice. The various amps and the Fryette Power Station did color the sound a bit where as the LX II is neutral but without the sterility of a solid state power amp. There are some features that really make it responsive and feel nice under the fingers and give the power some dimension and bloom, feel, tube amp familiarity that nothing else I tried did without losing something dynamically or coloring something. I am very please with this power section.
The Kemper Kab is a trip. It is cool and it does it's job beautifully but I am still mind bent on having 1 speaker instead of 8...lol. It can handle the volume fine and it does sound nice. My regular cabs colored things and I was looking for neutral. By no means did using regular cabs sound terrible, I was simply looking for a purity in the profile and an in the room feel that felt like a cranked tube amp and a 4x12 or 2. This set up has gotten me the closest by far. I could see filling a 4x12 with he Kemper Kones and that could solve that very small % I am missing. I could see getting another Kemper Kab and spreading them out and that could solve that last little bit of a problem in fullness in the room.
Talking very pure tone, the rig as is delivers. The sound is right. The feel is right and the volume is there. I would be lying if I said there wasn't a difference in the 1x12 vs a 4x12. There is a bit but it is a small bit. I don't believe what I am talking about is a sound or volume thing but rather a space thing. a filling of the room standing in various spots while playing kind of thing if that makes sense. From that perspective, an additional Kab could be a benefit but it would be small. A 4x12 cab with the Kones could be a benefit but again, small (and expensive) for the 4x12 cabinet cost and the 4 Kones. I hope what i am saying makes sense.
This way has been the best for me to get that tube amp in the room feel and that punch in the chest sound, pant leg flap of the almighty chug. I have also come to realize that One thing will never be another thing no matter how hard you try. Heck, I have plugged into identical amps and been able to tell a slight difference. I say all this to say I have embraced what this rig is all about and I am going to enjoy it for what it is. My tube amp and 4x12 collection will not be going anywhere and in fact will be growing. This Kemper is a fun piece of gear and does a lot of neat thing (many of which I am probably oblivious to).
Hopefully this helps a bit and didn't confuse. Again, thanks to all those who helped me along the way and contributed to this thread. I appreciate everything very much. Now let's all go play guitar!!!
