Thanks for the useful input so far guys. To further your understanding of the situation, the top shelf of my cabinet is not available for the CDP, as it is too high to reach to load and unload discs. This is the main reason why I chose to utilize the Audio Aero Prima DAC w/Transport (DAC now for sale), so as to enjoy a terrific digital front end, without a top loader.
However, my setup has changed slightly, and there is now room to at least consider the top loaders. I have thought about the move to the AA Capitole II, but that would be essentially a lateral move considering my Prima ownership.
That said, when I make a move, I generally like to move up when possible, as we all do. The problem is there seems to be very few one box solutions which would be a step up from where I am right now, and most are top loaders. The only thing I have heard in a one box which betters my AA Prima DAC/Transport setup is the Reimyo....which is very musical, but at 3 times the cost. Beyond that, SACDs/DVDAs are not that important to me. I have a few, which I use in another player, but I feel these formats are not going to survive the long haul, so I am not inclined to sink a lot of money into a player of either them.
As for now, the quest continues, but I do like the Reimyo. However, perhaps the long awaited Levinson 51 will be a contender. We'll see.
