Hi Valinar
Well, I like bookshelf speakers some because of how they can image and are small in my small living room (11x22) I have a powered sub to use if I want too.
I picked up a pair of Apogee ribbon speakers on Craigslist and like them, the ribbons are very quick and real sounding.
The Apogee Centaurs mate well with my P-300 power amp, but are large and a little ugly (not the best WAF) So, I got thinking about some stand mount ribbons and wondered who makes them.
The extension of the Centaurs in the highs are something to hear,but their ribbons are 26" long and that may be why they sound so dang good and life like.
It could be the smaller ones won't please me, but ,I thought I would ask around and research possibilities....
So, in answer to your question, it would be their openness that I love.
Thanks for everyone's suggestion too,I'm going to look at everything suggested.
