Which Speaker in the 4-6K Range?

During the last year, I have owned both Coincident Super Eclipses (listed at $5500 although Israel Blume will sell them to you directly for $4500 post paid) and the new Silverline Sonatas (at $6000 a pair). I think that they are both great speakers, but I kept the Sonatas. The latter had a more refined quality, better soundstaging, and a more controllable bass. However, I don't think that you could go wrong with either.

If you look past your list, look no further than the Dunlavy IV-A. They are everything you want and more. They do sonically disappear but visually..they are big.

Go for the Super Eclipse.

Maybe I'm the new kid without being in the know (I haven't gotten to listen to most of the previous speakers recommended, but nonetheless here is my 2 cents: Kef Reference Four Model Two. They meet all of your criteria, and are gorgeous. I wish I had the extra 2 grand to purchase them when I bought my SL-3's (which I adore). A local dealer played the "dark side of the moon" and I was hooked, it was like a religious experience. I didn't know "traditional" speakers could sound that good.

Within your budget and specifications there are but two contenders: the silverline Sonata and the Coincident Super Eclipse. I am less familiar with the second. I heartily recommedn the Sonata. You cannot go wrong either way, but get good, clean amplification and the best front end you can afford, and make sure you have a good room, since these are revealing speakers !
