It's funny, ESP speakers is on my radar for musical speakers down the road, and I'm circling Wyred, but I have yet to make a commitment. I woke up an old pair of Audio Physic speakers with a digital receiver a while ago and I have become very interested in seeing what their potential is. Little did I know the speakers were 4 ohm nominal and my old tube amps could never be up to the job. Anyway it lead me to single driver speakers, but that's another story...
It sounds like you had a similar experience.
