Unless you have a very large room, I would suggest the X5's, but check with Clayton. I will tell you this....the current lineup of speakers by Clayton are miles ahead of his previous Emerald Physics offerings. Years of tweaking his designs, and the use of advanced parts and materials have Spatial Audio Labs at the forefront of OB designs. If you liked EP's, you'll love Spatials. BTW....I, too, owned EP's for a short time and now have the X5's.
