Great system, I love MBL gear myself. It reminds me of cool, pure, running spring water. I had watt/puppies for a bunch of years, and IMHO Wilsons are probably a tad more accurate, but the MBLs are infintely funner to listen to, and I never ever get listening fatigue, first speakers I have been able to run SS with in 12 years. If I could make a small suggestion, it would be to try a TaraLabs the One power cable on your pre-amp. You might be very very surprised at the gains, I was never a big power cord upgrade guy until I heard it. At any rate, welcome to the MBL band of brothers.
Cheers!
Chris
