I don't have the Epiphony that you are asking about, but I have the Nightingales. I am extremely impressed with the sound quality these Odyssey speakers produce, especially for their size and price. I can second Tsugury thoughts on sounding bigger than they appear. I had a pair of Paradigm Studio 60 v2 that were much bigger and had a lot of great press, but they didn't hold a candle to the Nightingales. For their size they pack a hell-of-a-lot-of bass. I've heard similar comments about the Epiphany speakers too. Do a search in the Odyssey forum of Audiocircle.com. I'm sure you'll get plenty of info.
