Whats the best cable size for spring loaded terminals

1.5mm. That'll fit just about all, though you may have to jiggle about with the spring tag if they've been a bit stingey with the hole size.

How long is the cable run?

For short cable runs - under 10m - the difference in power loss between 1.5mm cable and 2.5mm cable is 2%. It's neither here nor there.

Will a 2.5mm cable fit in a 2mm connector?

I very much doubt it. When you strip the outer sheath the strands start to spread out. Some will miss the hole and spread out. The risk then is shorting with the cable in the next-door spring clip terminal.

Besides that, why would you want to go through that hassle?

You've said the cable runs are "extremely short" (post #4), and I said that the difference in power delivery between 1.5mm and 2.5mm cable at 10m is less than 2% which is an insignificant amount. For a shorter cable then the power difference gets smaller too. That's basic physics; shortening cable length reduces resistance and so decreases power losses. Making the cable thicker reduces losses too. However, you have to factor in cost and convenience too. Thicker cable costs more and is harder to route and hide. You won't gain any worthwhile power advantage at a 10m run length, so if your cable runs are shorter than that then there's even less benefit, but the thicker cable will cost significantly more and be a hassle to fit. Where's the upside here?

You have to be careful mentioning physic, when audio comes into it. Some people think you need 6mm square unicorn hair gold plated or it will sound rubbish :cry: .

Pfttt to your low standards. It's 7mm unicorn hair gold plated for me I'll have you know. :D

We tried platinum, but having the butler polish it every day was becoming tedious.
