HARBETH ARE DESIGNED TO WORK WITH A WIDE VARIETY OFAMPS.IT'S HARD TO MAKE AN INCORRECT CHOICE. I SUGGEST YOU CHECK OUT THE HARBETH USER GROUP SITE AND READ UP ON ALAN SHAW'S DESIGN PHILOSOPHY. M30'S DO BENEFIT FROM A BIT OF EXTRA POWER. BASS RESPONSE IS NOT REALLY AN ISSUE, IN THE RIGHT SIZE ROOM, AS THEY GO PLENTY DEEP, UNLESS YOU ARE A REAL BASS HEAD, IN WHICH CASE THEY AREN'T THE RIGHT SPEAKER FOR YOU ANYWAY. IN A LARGER ROOM, ADDING A SUB IS AN OPTION. I USE A BAT 300X SS INTEGRATED AMP. SURPRISINGLY, IT WAS WHEN I UPGRADED TO A REALLY FINE SOURCE ( ESOTERIC x03) THAT I COULD APPRECIATE THE M30'S SENSE OF "BEING IN THE HALL." THE M30S ARE GREAT SPEAKERS. CONGRATULATIONS
