Which basic amps can drive 1 ohm loads ?

I had a KSA100 for a while but it blew transistors so I got rid of it.

Some of the Adcoms are suppose to...but I would try a professional amp like Peavey,Crown,and the like .These are designed to handle the tough ohm loads and do it all day!

Good Luck!

I am using a Pass Labs X-250 to drive MartinLogan Aerius i's, which drop to 1.2ohms at 20Khz fully driven.

Though it does spike the built-in power meter pretty hard on heavy treble transitions, the amp NEVER sounds stressed, and seems to be designed to shrug off this kind of load. If anything, these speakers are now the weak-point of my system - not the amp.

YMMV - This is only my personal experience - I don't know everything - please do not flame me.

certainly Innersound ESL amps...Roger designed them especially for electrostatic speakers....

My Krell Ksa-250 will drive a 1 ohm load, it's rated at 2000 watts per channel@1 ohm. As a matter of fact I am looking for a pair of large Apogees in the near future, I have a pair of small Apogees now and have caught the Apogee bug it seems.
