What do I need to run my maggies?

This is what I have:

2 x Magneplanar MG 1.6 Front
1 x Magneplanar MG CC2 Center
2 x Magneplanar MG MC1 Rear

I need the rest. I understand the 'rest' to be a 5 channel power amp good for about 300 watts @ 4 ohms AND a separate 5 channel AV receiver to handle all the ins and outs? Is that correct?

If so, what do I get? I have a budget of just under $2,000 USD and I need all the latest types of connection (HDMI and USB) but I don't need multiple zone capability.

Thanks - rev
