Given what you're looking for I'd seriously consider a tubed preamp. ATCs are awesome speakers, but they seem to do more of an upfront presentation that doesn't do the 3D holographic imaging thing as well as some others, and a good tubed pre might help with that along with helping your system sound less clinical. One I've been looking at is Vacuum Tube Audio SP14 by Don Sachs. Pretty sure he offers a short demo period, which is nice, but it would also leave you enough left over to get your Oppo modified by Ric Schultz at Electronic Visionary Systems. I'd think these two together would make a huge difference in your system and in getting you a lot of what you're looking for. Best of luck.
