The latest changes were to bring up the weaker components to match the stronger ones- the Pass X250.8, Constellation preamp, and Magicos. My fellow audiophiles and civilians agree that the improvement over the past year has been such that it sounds on another level. This is especially the case with the analog part, but the digital is enjoyable and sounds better, The cabinet housing the components required reconstruction to accommodate first the amp and then the larger turntable. I had to give up quite a bit of album shelf space to make room for the Pass and its ventilation requirements, thus the shelves above the audio components and the new shelving area in the book stacks.
