After, my usual researching to death bit, and listening too, of course, I have decided to purchase the Audio Aero Prima. What I have compared it to really doesn't matter. Does it? YOU, really have to listen for yourself and let your ears tell you. All the listening adjectives you'll hear, are merely that; words. You must listen. I'm sure you'll get enough posts to give you a nice framework. Now I, first hand, have not heard the Gamut, which everyone seems to love. I do know people who liked the AA better. I, also, know people who prefer the Gamut. It's wild out there. If you can audition the Prima your tympanics are going to tingle. Lists for $2200, but can be found nicely discounted. Good hunting.
