[QUOTE="croak, post: 41669, member: 361"] Further to ampdogs comments, I would say you could use amplifiers from anywhere in the world, the key here will be to audition before you buy, preferebly more than one option in your budget and decide what works best from there. Yes, they are a tough load and as ampdog says quite unpredictable as to what parameters exactly will make a match or non working combo without going testes to the wall overkill. Physically heavy amplifiers with modestly claimed watts for their weight arewhat you are probably after. Depending on room size and listening distance, minimum 100 W in to 8 ohms I would say and the closer that amplifier performs to the theoretical perfect of doubling as driven impedance halves is good. This is not foolproof though as the doubling requires a stiff powersupply and output devices that can handle this extra current and heat. In practice an amp that does 100 into 8 and 170 i to 4 may workevery bit as well as one that does 100 and 200. stay away fro 100 into 8 and 140 or in to 4 or worse. [/QUOTE]
