If I may toss in some thoughts....
Prior to Friday, I had never heard any Salk speaker, so I lack the depth of experience that others have. Nonetheless, I was blown away by the Exotica lll speakers........I didn't listen to the SS8s until Saturday afternoon (and still have not heard the Song Towers!). If I hadn't heard the Exotica llls yesterday, I would have said the SS8s were fantastic speakers.
Now I know something I did not know a few days ago. If I decide to buy Salk speakers for my next speakers, they will be Exoticas, not Silks or SS8s. I speak of the bookshelf version BTW. Given my room constraints now and in the likely future, full sized speakers won't work so well. I would buy one (or 2) Rythmik 12s to support them. I spoke with Jim about this idea and he said it would work quite well [although not so well as the new Exotica llls, of course..].
I'll continue to make comparisons on Sunday, but I'm fairly certain I prefer silk dome tweeters over ribbon tweeters. I understand not everyone shares that viewpoint, but I listen with my ears....and I trust them.
More later....
