Pioneer S-1EX Loudspeaker

Has anyone heard the Pioneer Center Channel S-7EX to pair with TAD or Pioneer speakers?

Have all 5 speakers of Ex series. The S-1 is very good. My listening interest is strictly classical & opera. The S-1 comes into play with SACD's & the Living Stereo & Mercury 3 channel reissues. Worth every penny.

I have the s3ex and it is awesome. Instruments are very realistic. It blows away my psb synch1 and dynaudio c1 sig. Anyone who know a dealer who still has a stock of the s3ex? I have a friend who wants to buy one.

I had the very best from KEF for a few years. I came to recognize a severe distortion and ringing, and sad to say I here it in every concentric topology including these otherwise wonderful speakers. Without fail, every time I listen to this topology it is there. For example, every one is praising the LS50 stand mount. I thought that this could be the one to break free of that distortion/ ringing. But I only had to listen to it for `1 minute to hear it loud and clear.

All I hear is music.
