Would cleaning the resistor leads freshen up the sound?

Your question gave me the urge to try. I used Cardas contact conditioner/cleaner on the resistors of my Sophia 3's. First, I really have to tip my hat to the folks at WA. The quality of the parts & the workmanship is amazing. I cleaned all the contact points using the conditioner and I did notice a difference. The music became noticeably more dynamic.

Damm,
I was hoping you would say it made no difference. Looks like I need to clean my mids and tweeter resistors.

I guess you wiped the two wires on each resistor as well as the screw in section?

What is the best thing to clean them with? Debbie?.
What is Wilson's recommendation?

Can you use methylated spirits or Brasso?

Cheers

If changing non-blown resistors helps as well as cleaning their wires and soldered connections, maybe the capacitors and coils in the crossover should be changed too.

Correct! I cleaned the 2 wires and the screws. I highly recommend using the Cardas contact cleaner. I've used for cleaning the PC pins, interconnects and speaker cable spades & speaker screws and you can hear the difference.

I look at changing resistors like one would when changing out spark plugs in a car.
You're waisting your time and money, the only resistor that ages or deteriorates is made of carbon. Over time the value (resistance) will increase. I can't imagine Wilson using anything but metal-film or wire-wound high precision resistors which have a very stable and long life span.

Actually, you're not wasting your time & money. WA does recommend changing resistors every couple of years. Wilson does use good Caddock resistors.

So where did that recommendation come from?
Never heard of replacing their resistors from anyone, be it dealer or factory. Ever
If it was a WA recommendation, why wouldn't they say it in their manuals?

Doesn't make any sense...

^^^^ I'm with you!

Resistors [that aren't burned out] are about the most stable components in a speaker.
