This is my retirement system. I started putting it together 5 years ago. I carefully replaced all the components that I had purchased from 1985 to 2004 one at a time to ensure a good synergy between the components. The latest addition, my new Dynaudio Contour Legacy are quite special. They replaced my Harbeth 30.2 40th anniversary which were great. Not easy to find speakers of this caliber for the size of my room.
Congratulations on your system and your view. Stacking your preamp on your CD player is less than ideal. Placing the CDP-10 beside your TT and the pre directly on the shelf will likely give you a free improvement in SQ.
