I've had my Quicksilver Minimite monoblocks for the past 17 years and still truly enjoy them with some of my British monitors. Linn Kan I and KEF Reference Series Model I (similar to the LS3/5A BBC monitor). If you can find a used pair in nice shape for around $750 I think you'd really like them.
If you want to purchase new, then the Quicksilver horn monoblocks at around $1600 the pair might make sense. They're 25 watts per channel but sound much more powerful.
Good luck! 😀
