From what I know from some reviewers about SETs and I have read a lot the Mini Utopias will be successfully driven by the 24 watt Jota (high current version).
Some SETs have even been reviewed driving the Mezzo Utopia which is a heavier load.
24 watts of SET power is not the same as any other 24watts.
In the SET category a difference of 5 watts is a lot.
Some reviewers have driven the Wilson Watt/Puppy 7 (nonimal impedance 4 ohms) with a 23 watt SET to a satisfying results.
It is true that the Watt/Puppy is more sensitive than the Mini Utopia but still they are a heavier load having in mind their impedance variations.
The Mini Utopias are relatively small speakers having a nominal impedance at 8 ohms (Correct?) and I think that the Jota will drive them to satisfying levels.
At least for me ...
Your pre-amp should do in my view.
