Best High Current amplifiers stable into low impedances

Seems like all I hear when reading Stereophile’s measurements when it comes to speakers: must be used with a High current amplifier stable at 2 Ohm. Most amplifiers rarely give specs related to 2 ohm loads. Most amplifiers are only stable into 8 and 4 ohm loads, and if they mention 2 ohm it seems they aren’t saying continuous, but peak, short term power.
With speakers becoming more complex and harder to drive, what are some high current amplifiers that have no problem with these 2 ohm or lower impedance speakers?

Sunfire amps can work with any load stable.

Anybody know what the status of the second iteration of Purifi amps. These new ones are supposed to be much more powerful than the 200 watt first version.

Seems like several of the boutique Purifi builders, Apollon, Rouge, VTV, March, are using the new module, but none of the big boys have come out with a new model yet, AFAIK.

I just checked the VTV site and the specs are not too bad.

950W @ 2Ω

500W @ 4Ω

250W @ 8Ω

I think I I need to give one of these amps a try before I buy an old school amp for my Livingroom. I love the sound of the Benchmark AHB2 (that is no sound). Though the AHB2's power in 2 Ohm is lacking in stereo and definitely  in mono.

The Purifi modules are supposed to be almost as good as the AHB2 but with better power specs at 2 Ohm.
