how much power

Roxito why not ask people in the speaker forum who have your speaker what they are driving them with and if they may have tried other manufacturers as well;I do not think you should really be just looking at the specs and then buying;what you are trying to find is a proper match of amp to your speaker and maybe the 50 or 100 watt issue does not even come into play.

appreciate the responses.

Get a Kreel amp and you will have all the power you will need. You can never have to much power.

Good suggestion about Kreel:-)! I'd probably pick KSA250. It drives anything by any means!

I once believed the"you can never have too much power" credo. With exposure to the high quality low watt amps I discovered superior sound and better music reproduction(more natural and real i.e. less hifi or canned).
As long as there`s sufficient power for a given speakerload, the simpler less complex amps usually out perform. YMMV.
