Can't say anything of Trivista models of MF but all previous models seems to me too much overrated and do not correspond to the real power ratings.
I guess that the budget choice should be McCormack separates such as DNA2 with TLC or any passive preamp or Bryston monoblocks that could be successfully driven with the same McCormack passive pre.
Another way is Plinius separates that is underrated with their current and power delivery capabilities that could drive anything that is currently produced for instance even Plinius SA102.
You can go tube way such as VTLMB180 that is stable to 2Ohm loads but may lack bass but with super mids and highs clarity and overall soundstaging and resolution.
