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?

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.
I agree with Pubul57 choice of the merlins and would add Dunlavy scIII,scIV,scV and scVI's into the mix;these are speakers that you could listen to forever.
I would also vote for my current speaker soundlab m2's except impedance curve and listening levels my not appeal the masses except I can listen all night long and not want it to end due to listening fatique or any other reason such as that.
