Very few amps are stable into 2 ohms, you’d have to look into truly high end stuff. Maybe Pass Labs, Krell, Conrad Johnson. But you may not need 2 ohm stable. Why are you asking for this rating in an amp? Very few speakers dip down into 2 ohms, I can think of an older model of Infinity speakers.
It might be cheaper for you to ask what owners of your speakers are having success with in amplifiers as well.
