I need to find a "audiophile" quality DPDT switch for a speaker passive crossover.
The switch will not be used during operation... i.e. when no music is playing.
It will be used to switch certain components in a crossover.
Is there a good recommendation for this?
Thanks!

Just about any DPDT switch rated for 3 amps or better will do just fine.
You can search out an "audiophile"one, if you want to pay 4 times more for the same thing.

I recommend higher amperage capacity for the reason that contact resistance will be lower. This was covered by an ABX comparison in DC awhile ago, about 2005. The larger higher amperage relays were used as a litmus test compared to the lesser units to see if the difference was audible, and it was to the majority.
When I'm doing switching in my xovers for parts swapping, I usually go for the 10A rated 'heavy duty' toggle switches. I know it seems like a lot of current capacity, but the contact resistance can be reduced a lot.

I'm not sure how much difference it actually makes, but hey, it can't hurt.
Or you could do it "old school", like this...
... things were darned near indestructable.

An externally hosted image should be here but it was not working when we last tested it.

Interesting, but point made that the circuit impedance is what it is regardless of the current that's being pushed.
Which is why the contact resistance can matter. Some tenths of an ohm can change tonal balance.
I'm glad this was good food for thought,

So what would be the recommended approach?? again its to switch certain elements in a crossover... and the switch would be in the signal path. Unsure if I can do it with jumpers... and would having jumpers be any advantage over a switch?
The first two answers "just about any switch" and "recommend higher amperage" actually answered your question. The rest is just people being stupid.
