I found the Stereophile review of these speakers:
http://www.stereophile.com/floorloudspeakers/monitor_audio_platinum_pl200_loudspeaker/index.html
The reviewer found the recommended power was at least 100 watts per channel. He used a SimAudio W-7 and a Primaluna Prologue Seven.
Are you interested in tube or solid state? And what kind of budget do you have in mind?
