I have repeated ad nauseam on this and other forums that good, clean power and "taming" vibration and resonance unleashes the full potential of any hifi installation. No need to upgrade until the very basic premises on which good hifi rests are fully implemented: (i) good, clean power and (ii) vibration and resonance mitigation.

Thanks for posting that, very useful.

10. Replaced the resistors on the Alexia Vs.

Why there is the need for replacing them in the first place? Totally irrelevant.

This is OT but since it was raised above.....
Replacing the outboard Vishay resistors on the Wilson speaker crossover for the Alexx V and some of their other speakers (Alexia V, XVX) once a year or so (depending on how often and loud you play) is a very real observation and recommendation by Wilson. The obvious question is, if the resistor isn't blown, why does it need to be replaced? The answer is- I have no earthly idea but it's an important thing to do- it matters sonically. I've had discussions about this with some of the Wilson folks and can't say I was impressed by their answers, but I can't disagree with the sonic benefits of changing the resistors. It's a few hundred bucks for very tangible benefits. Just do it! You will likely find the speaker sounds a bit smoother in the upper mids and highs when the resistors are changed. My preference from my crossover building days would be to use identical value Caddock 311 series resistors that don't depend on the heat sinks currently utilized for the current Vishay resistors, but I haven't succumbed to temptation yet and probably will not. You can bet however, that Wilson is probably going to move to different crossover resistor technology in future models. There's nothing sonically wrong with the current configuration but it would be nice to find resistors that don't require recommended yearly replacement.

All resistors degrade over time. I think this is a neat solution to keep things fresh.

All resistors degrade over time.

^Ok^… how?

I think this is a neat solution to keep things fresh.

Most resistors are not hydroscopic, are not
Oxidising, and are not corroding.
