I was once talking with the owner of Joseph Audio and he told me that the connectors and wire made more of a difference than caps in sound. He uses Solen caps and Cardas wire and connectors. This is the advice of someone who spent over a year full time designing a speaker.

50R will be fine - their spec is +/- 10% anyway.

Thanks, I read it as 1%, that was the contact min resistance.

its doubtful you will turn it up all the way anyway, in which case 47r is just as good as 50r

and vice versa

Is there a benefit either way? I have loads of .25watt MF so unless there is a reason to not use them I will do so.
