Tom, welcome. If you like the features of the 3808 and it fits your budget, go with it. You don't have to worry about "overkill" in the sense of endangering the speakers, since speakers take only as much power as they require for a given sound output; the amplifier doesn't force it into them. You'll likely use considerably less than the maximum power capability of the 3808.

Enjoy the music, not the equipment.
