Tweeters, Scanspeak or Seas

If you're familiar with tube brand characteristics, I would compare the sound of the Seas to Brimar and the Scanspeak to Siemens. The Seas sounds less defined, very relaxed, pillow soft on the edges of the notes, totally non-fatiguing. The Scanspeak has a bit more sculpted presentation, also non-fatiguing but with perhaps a little more shape and jump to the vocals, in a word, articulate. Pick your poison, as both are very good.

Velo62,
If you are a fan of the Dynaudio Esotar tweeter in your Sonata III's, I think you will find the Scanspeak to fall in between the two, sharing some of the chiseled focus of the Dynaudio and some of the emotional warmth of the Seas.

Let us know what you decide, and how you like the outcome...once you've allowed some major break-in hours on the speakers.

Jm labs titanium, B&W Nautilis, and the Esotar Im ready for something a little less forward and revealing.

Gotcha. Either of these options will be more relaxed and forgiving than those you mention. The Scanspeak is a step in that direction, and the Seas yet a bit further. I'm sure you'll be quite happy with your choice.
