The upcoming LP appears to have a much smaller footprint than does the LC.
The LP using an external PS is going to be a good chunk of it.

I think we have our answer to: "How can a balanced Liquid Crimson be smaller than the single-ended Liquid Crimson?" Stacked PCBs (actually think that's not true), outboard power supply, smaller components, intelligent layout.
I was was taking a gander at the Platinum yet again today and a couple of things stood out regarding the size:
I think we have our answer to: "How can a balanced Liquid Crimson be smaller than the single-ended Liquid Crimson?" Stacked PCBs (actually think that's not true), outboard power supply, smaller components, intelligent layout.
- Offloading the power supply to external saves a ton of size/weight. It will also potentially cripple some of the amp's potential without some really good cleanup once inside the chassis. I'll be using a linear power supply with the Liquid Platinum for sure.
- Looking at an old shot of the Platinum seems to show two PCBs stacked on top of one another. Am I crazy? That's what I think I'm seeing in the shot, which would certainly account for most of the rest of the size difference.
- Edit: Yep, looks like that 2017 prototype was stacked. See the last picture.
- Edit #2: Actually, looking closer, I think that lower PCB is just an unpopulated board to keep it offset from the table. Shrug. I suppose there's some stuff going on underneath too, but I'm no amp designer.
- And, of course, shrinking (nearly) everything down to SMD components. The Liquid Crimson has a lot of electrolytic capacitors and through-hole components.
- Also found a Cavalli CanJam 2017 thread worth reading with comments from @runeight.
This is a gut shot of a Cavalli Liquid Crimson:
Here's a picture from about a year ago of the Platinum:
