Most Class A amps can do that as they typically have robust power supplies. Sanders Magtech, maybe Krell, Bryston, Parasound, Coda, McCormack etc.. I’d guess that most amps that near double into 4 Ohms would likely also handle a 2 Ohm load.
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?

I went through the 2 Ohm dance with my now sold Thiel CS3.7 speakers. I thought newer speakers were easier to drive. The amp I am likely going to get for my Livingroom is the KRELL KSA i400. It is 400 watts of Class A (depending on demand) at 8 Ohm. It doubles down to 800, and then 1600 watts. It is supposed to be able to double again to 3200 if your power source can provide the current. I do not think that 400 watts of Class A will double, nor half. I remember an interview with the designer where he said it stays at 400 watts of Class A when it is doubling. SoundStageNetwork.com | SoundStage.com - Talks I have the KRELL Dou 175XD that has similar tech as this new amp. I love the 175XD, which I use as a headphone amp (’ear speaker amp’). The CODA #16 also doubles into 8 - 4 - 2. It is a great sounding amp. |
