Multichannel amps that can drive low impedances?


A friend has asked for advice on a multichannel amp to drive some speaker designs he is building...he wants a multichannel amp good down to 1 ohm. Budget is around $3000 used.
I've never heard of one...any advice? If nothing else I guess I could tell him to get some older Krell monos.

ANY solidstate amplifier will drive a 1-Ohm load. The question is just how much current (hence power) can the amp deliver into 1 Ohm. Some SS amps will double twice to 2 Ohms but I'll bet very few of them will double again in 1 Ohm. The class-A-biased Lazarus HA-1-series amps will double twice into 2, from 50wpc/8 to 100wpc/4 to 200wpc/2. The Proceed BPA- and HPA-series amps will double at least once into 4 while starting with 125pc and 250pc, respectively, into 8 and are available in 2- and 3-channel versions.

What is this guy building--something with 'dozens' of drivers in parallel?
