Bi-amp question .. newbie

I've been looking for an Arcam Alpha 8 or 9 power amp to match with an Alpha 8 integrated. Read a lot of positive feedback on result. But the power amps seem rare (been hunting for six months) but there are a fair number of 8,9 integrateds out there. .

Ignorant question: Is bi-amping with two integrateds an alternative? Should I hunt other brand of power amp and if so, any good matches?
