Any high powered receiver will do the job. Dave Wilson did a demo with a receiver to show that the speaker is what mattered.Yeah, a receiver will "do the job". A Prius will "do the job" too, but I'm not a fan for obvious reasons. But your premise that the speaker is "what maters" is silly, A receiver will always be a sub par piece of audio gear targeted to the unwashed masses. If you want to hear what any speaker can really do, it's the last thing you'd want.
