Which basic amps can drive 1 ohm loads ?

Kool, nobody runs Aragons on Scintillas. Duettas, Divas, Calipers, yes, but not Scintillas. Scintillas run on an average 1 ohm, and dips down to .6 ohm. This pulls a tremendous amount of current through the amps, causing huge temp rises. This requires giant heat sinks or fans, neither of which the Aragon has.

Audioman, most every?

I believe the Jeff Rowland Model 8T and other iterations including the 9T should also do a good job with Apogees - 50A continuous, 100A peak. Not cheap but they do the job.

Classé DR3VHC will do the job,a pair with the right AC cord
will be better and sound excellent. And DR 25 not bad at all

Actually Apogee speakers are not a highly reactive load. They are mainly a resistive load. Only the Scintilla ran at 1 ohm. Most other ribbon models run in the 3-4 ohm range, a horse of a different color entirely.

Actually the Scintillas have a 3 ohm wiring option, but don't sound as good this way.

THe old Krell KMA-100 and KMA-200 monoblocks were built with the Scintilla in mind.

A 1 Ohm load will barbeque most amps.
