the smoothest sounding speaker


Any recommendations for a smooth sounding speaker? One that won't give you ear fatigue playing CD's. One that doesn't require playing vinyl to sound good.
Vandersteen's come to mind but I would like better resolution. How about Aerials? Is it possible to have both good resolution and still non-fatiguing sound?

I own Hyperion 968 and I believe it's very smooth sounding speaker. Not to the point of boring like some British speakers, though...
Spendor S8e. Very smooth with wonderful midrange texture, strong tight bass, and beautiful non-etched relaxed and nicely detailed highs. Their fuller bass and midrange texture won my vote over some Dynaudios.

I think (as of today) driver distortion is my biggest detterent to enjoying the music. I can live without all the detail, bass, or treble, but if distortion is high.....no way.
Then, I would think electrostats or planars would be your first, and natural, choice.
