Alright, I've slacked off long enough in giving my review of my E680's. Sadly, all I have is cell phone pictures for now. My girlfriend returned from her trip and informed me that the screen no longer works, so I'll try borrowing one this weekend.
Right now, they have around 30 hours on them. I spent the first 10 playing music with them at a fairly low volume in order to break them in. I listened to them for about an hour and they sounded great. Even on low volume, they still produced decent bass and the highs sounded quite detailed.
After the first ten hours, I started watching some movies, but still at lower volume than I would have preferred. First, let me just say that I now have a new love of watching movies. Even in a stereo set-up, the sound is so much more immersive than my old HTiB. The first thing I did was pop in Master and Commander and watched both the opening battle and the Cape Horn scenes. The bass in these scenes was unbelievable for not having a sub, especially the opening battle. I also watched The Dark Knight and I had to resist the urge to crank the volume, it sounded great.
Once I got to about 20 hours I started setting the volume a little higher. I watched teh first episode of Band of Brothers and while it isn't an overly loud episode, I appreciated what the Jamo's were able to do for quieter scenes. I was able to pick up a lot of subtle details I hadn't heard before. For example, in the tunnel scene in I, Robot, when Will Smith is crawling out of the car, there is a female voice that says something about the sealtbelt or the airbag (can't remember which now) that I hadn't heard before (and I'm pretty familiar with the film).
I also watch The Island. The movie had a lot of bass (it is Michael Bay after all), which the Jamo's produced well. One proplem I noticed is that during certain scenes in the movie (and in Shoot 'em Up as well) is that voices would get lost in the action. I attribute this to not having a center and I'll rewatch this movies once I get the S 50CEN hooked up.
Overall, I love the sound of the Jamo's and cannot stress auditioning before you buy. I'll try to get a real camera and post some pictures. I have a pair of S 506 floorstanders that were part of the auction with the S 50CEN, so I'll be able to compare the them to the E680's once I get them set-up and broken in. Any questions, feel free to ask.
