what matching amp?

Just about anything! This is actually a positive. The better the amp the better the speakers will sound, but they are not difficult to drive. Classic integrateds from NAD, Onkyo, or HK are plentiful and a good place to begin. I used an Onkyo A-9 for a year.

I would consider nad gears. If you don't have a quality source, consider this all in one DVD-receiver at a good price:
