So I would be interested to see what the answers would be if the OP had specified "at the same price point."
Which is why I answered the way I did. These sorts of questions are without qualifiers pure flights of fantasy. The OP at least did qualify it a bit by asking about connections. Still that is not much of a limitation. As anyone can see already we have not only separated into pre-amp and amp but even more separate boxes for power supplies for the separate pre-amp and amp.
I get why no one wants to talk about total cost. Throw in total cost, require people to actually listen to the whole package, it suddenly becomes very hard to find separates that even come close. But hey flights of fantasy are fun. https://www.youtube.com/watch?v=QH7hj1nauTc
