Class D

One D amp that won't "reduce clutter", as OP says, but can easily handle a 1-ohm Apogee Scintilla is the H2O Audio S250 Signature.
Uses older Ice modules, 250W/8-ohm, doubling down, a really healthy power supply, dual mono in one chassis with two toroids, 70-lbs.

Oh...it's also rare on the used market so don't hold your breath. 
I'm sure there's some special circuitry somewhere but it's pretty basic otherwise. It's all in the design and execution. Point is, class D can properly drive 1-ohm, not just be stable there, if so designed. I don't know why more manufacturers don't make the effort.

Fine with D...can't wait for E...*L*

Earthquake beginning! 

Hi, has this conversation degenerated to fake data, or specifications that have no bearing on actual listening experience?

If so, I'm in!

No, not on my end. An amp that can easily handle a Scintilla, not just handle but do it beautifully, is a breeze with any other speaker. Several users on the old Apogee forum agree and they are fanatical about their Apogees! I was less fanatical for mine especially when they needed restoration and I had to let them go - along with the amp.

Price is not bad at around $3500, if I recall. Problem is Henry Ho is tough to get a hold off, as it seems this is a sideline for him. I can pass along his email to anyone interested.
