Instead of getting the m80s I got the m60s and so far I am pretty happy with them right now. I guess I don't know what I am missing since I have not heard the m80s yet...

What if I take that extra $300 dollars or so and invest in a better AMP, let's say a Yamaha RXV1700 and bi-amp the m60s? (I have a crappy sony 70watts right now...)

any advice on that? \:\)
