I would not switch just to switch unless there is something specific about Class D that appeals to you?
I’ve been running Bel Canto ref1000m Class D amps now for a number of years and still could not be happier. I did this because I wanted to throw the kitchen sink in terms of drive ability at my speakers which are known to benefit from that. I wanted something capable and good sounding that was also not too big, heavy and hard to deal with. Budget was limited but these fall into your price category at least the original retail price, though I acquired used for a discount in order to give it a try.
Still couldn’t be happier. If Class D did not work out I probably would have investigated building a smaller system around tubes but feel no need to explore those waters since. I’ve added other lesser Class D amps in other systems since. It’s the only way I go now. I do use a Audio Research sp16 tube pre-amp with my ref1000m Class D amps and think that is a very good way to go if one does not mind having to deal with maintaining a handful of tubes from time to time and the specific amp used has higher input impedance 60Kohm or higher for use with a tube pre-amp. No tubes in my 3 other setups built around Class D and those are all similarly good as well within their significantly lower drive limits (and cost).
