Good luck with the D7.2's. I own the D7's and adore them. I drive them with ARC DSI200, which is a solid state integrated that was released 10 yrs ago but which I bought the lightly used demo unit from dealer about a year ago. It sounds amazing to me, and that integrated amp is available used within your budget.
At least a few in your list above include dacs. I know the Hint 6 and SA30 both include ES dac chips. They would give you some flexibility in mixing and matching with your Ygg dac to suit different sound styles, potentially. That's one way to look at it; another way would be to conclude that their dacs are redundant and you don't need them.
If you thought the Hegel was missing some bass and warmth, the Parasound from your list may do well. But that's just a guess as I haven't listened in detail to any of your choices.
If your D7.2's aren't well broken in yet, you'll certainly gain more bass and especially warmth from them, in particular as the LPZ tweeter rounds into form as to the latter.
Good luck.
