The Medieval To-Do List is pretty full.

Still, it would be fun.

I owned a pair of Apogee Scintillas before getting the Full Range. The Scintillas sound much better using the 1 ohm connection instead of the 4 ohm connection strap option. You lose dynamics with the 4 ohm arrangement. I had a pair of Krell KMA100 monoblocks that produced a warm yet powerful soundstage. The KMA100s were one of the best amps I have owned. You still may be able to find used KMA100s.

If you want to DIY, you could build the KSA100 that is well documented on diyAudio. If you only plan to drive a 1 ohm load, I would recommend using a lower output supply voltage say 16V - 20V. You want high current with a save operating range on the bipolar outputs.

Yes I have them too but they're still orig. packaged from the first buyer I buy them from, waiting for the power amps to drive them... I also have a 4 pcs. 1,2 KW toroid transformers with 34V 0 34V secondaries waiting to be used. I read a lot of various reviews and there are only a few amps to drive them as they should be driven. I know it is an illusion but maybe one day will happen the Holy-Grail from Papa to us with its X (SicCarbide) version with enough op. trs. to make us heaven here on the earth...... will pray daily ....

Sometimes I wonder if people don't think this is Do-it-for-Me rather than Do-it-Yourself.
Take an F4 or a BA2 with well matched outputs, and lots of Heat Sink, lower the Source resistors in the outputs and raise the bias to 25-30Watts/device.
That should get you started. If you want the SS SiC JFETs in the output, you will have to go even further. On the order of 2 times more medi-evil. I guess you could build a BA1 with all 6 pair in the output and high bias?
"It was the perfect high end audio product: Exotic, inefficient, expensive, unavailable, and toxic." N.P.

Would F5, F5 V1, or F5 V2 be able to drive Apogee Scintilla or Apogee Duetta Signature?

SUNFIRE 300x2 or 600x2

1 or 2 ....

WITH THE "SCINTILLA MOD" (stable to 0.5 ohms impedance)

2000 or 4000 watts @ 0.5 ohms

But if it were me I would either build the F5TV3 with 8pr/ch or
the AlephX or F4X and double the transistors
And don't skimp on the PSU.
