there are so many things you can do. Since none of us are there it's impossible for any of us to fully know what to do. PUtting a real pre back into the equation makes more sense starting than most anything other than checking your room and placement. Personally, I'd go and buy a turntable for the type of music you listen to. Not to be a jerk, but your amplification has maxed out. That's the reality. SUre, they are fine to start off with, but as you see there are too many trade offs with the NAD or the Wyre gear. I was running the NAD on Proac Super towers with top of the line MIT gear, because I was told that I had to get remote into my system as I was using Quicksilver silver monos and full function Quick pre. The tubes sounded awesome and the NAD was, well, NAD. It collapsed the stage and everything else was ragged. Once I put my new Ayre into the system, it fixed most everything and made the speakers sing even better than before with tubes.
Bottom line is that you need to put a system together and not the best audio products according to a magazine or what we posters tell you is best. Synergy is what makes systems work and anyone who's been around this block will tell you that. I've heard those speakers sound awesome a few weeks ago with the Ayre AX7e integrated and all Audio Quest cables. It was even digital I heard it with, but when we put on a simple Rega 3 it all just relaxed and sang. I don't even love the Rega, but it relaxed the sound and I got into the music instead of listening to components. Good luck and let us know what you do and how it goes
