I recently heard the 3.5 with the Rowland Concentra II and they sounded marvelous. We also listened to the EAR 509 100wpc tube amps which were not quite as tight in the bass but very similar in many ways. The maggies need at least 100wpc to come alive. They have also sounded good with the Bryston 4BST, ARC D300 ss amp and Sonic Frontiers SFS80, but the latter at 60wpc was too polite in the bass. Jallen
