With limited exposure to various electronics, It would be wise to consider a system based an a single manufacturer. This would in theory resolve the issue of component matching. For instance, If you plan to go with the Proacs, you should consider the ARC products at your price points. Likewise, since you pleased with the Naim products, why not go all Naim. A CD5/82/250/D15 system would be quite awesome. Used gear would only extend your budget a little.
Good luck and welcome back to the High-end fray.
