I'm happily owning some Leak speakers again and am doing a few things to bring their spec forward a bit.

I have rewired them with Fisual Super Pearl 1.5 a nice cable I found via Amazon. I shall be using this for the amp runs too. That has I suspect rounded the sound out a touch but nothing amazing. I didn't expect much from new wire but with speakers of this vintage it's a cheap mod that's worth doing.

Next is capacitor replacement. None of the caps appear to be failing and the speakers sound wonderful though.
So is it worth doing and how much would you spend?

I'm in two minds about it. I've found some Vishay on RS for a few quid but do I spend more and where?

This is a long post for me so I shall end this by mentioning the final addition. Spikes or some sort of feet.
