Default Kef 104/2 - Power Requirements

I inherited a set of Kef 104/2s that have been sitting in a closet for 18 years. Most opinions I've found say that they need 150-200 wpc to get the most out of them, although the brochure says 25-200. I know I need to get them checked out, new foam, etc.
My father in law gave me a Fisher x 202 B tube integrated amp from the late fifties or early 60s. I believe it will deliver around 32 wpc. It might take a couple hundred bucks to restore.
My question is, would 32 Tube wpc be sufficient to get enough out of the 104/2s to do them justice, or will this be a poor use of this money and I should put get the 150-200 wpc amp? I'm not going to play music loud, bud do want to get the full soundstage and quality ehtese speakers are known for. I had some advice to update the crossovers to modern components that would result in less power needed, but saw the caution from AndrewJ on this forum that the original crossovers are a big reason the 104/2 sound so good and best not messed with.
I would greatly appreciate any and all advice on how to get the most out of these speakers, and how to power them without breaking the bank. and whether this Fisher x 202 B is worth putting any money into.
Thanks,
-Dave

32W...These are reasonably sensitive speakers, do you have neighbours?

The Fisher is probably adequate depending upon how big your room is and how loud you like to use them.

I ran mine off some various tube amps from time to time (incl Fisher 800B) but feel they were better with some hefty SS driving them.
