If you do not find what you are looking for in an Apogee (the user website mentioned above is excellent), you might want to check out redrosemusic.com. Mark Levinson's new company makes a hybrid ribbon speaker. The R3 Baby Reference is a bookshelf style speaker. I have not heard them, but as an Apogee speaker fan for many years I like to know what else is out there in case I ever need something new. Does anyone else have any experience with the Red Rose speakers?
