Speakers for vocalists

Are electrostatic speakers power hogs or are they very efficient? I have Rowland M201 amps and is that a good fit for these electrostatic speakers?

Most if not all electrostatic speakers are power hogs.

In general full-range, non-hybrid electrostats do indeed like lots of power, but quality is more important than a high wattage rating.

I'm a dealer for both Jeff Rowland and Sound Lab, and the combination works quite well although I do prefer the added power of the 501.

Single driver speakers that sound boxless. These can be fostexs or lowthers with tubes or (ideally) full-range, non-hybrid electrostats with tubes. Less ambitious boxes and crossovers can be bad. As a general rule, it may be best to avoid them. I suggest electrostats for human voice with the caveat for human voice and preferably no electronic instruments. Electrostats fare best with acoustic sounds. YMMV.

While I agree that my Magnepan 3.6's reproduce human voice fairly accurately, the thing that bugs me is that it produces too large of an image and soundstage. Its like a 6 foot mouth in front of me, does this bug anyone else? I guess soundstage and image height is both its strength and weakness depending on what is being played.
