Without a doubt the Raven preamplifier from Spatial Audio. The brainchild of talented designers Don Sachs and Lynn Olson, the Raven is end game for me. I hope my kids enjoy it as much as I do. Also, new interconnects- Paul Speltz level 5.3 balanced XLR AntiCables. These are amazing cables and very reasonably priced. Next up new tube amps to pair with the Raven.
