I don't think it takes a lot of power to drive any of those speakers.

The Epos speakers are better-sounding speakers than the Cerwin-Vegas, perhaps, and not quite as sensitive, so there might be some problems with matching up the channels.

For the best sound quality, I suggest either the NAD T748 or T758 receiver.

Please suggest me. Thanks.
